It was a dining-room, and there were three people having tea at the table: an elderly woman with a faint resemblance to Mrs. Everett, a girl with reddish hair and a pale skin, and the Levantine. Grant had time to note them all from behind the minister’s bulk before his host’s making way for him brought him into their view, and he had the exquisite pleasure of seeing his quarry recognize him. For a second Lamont’s eyes widened at him, then the blood rushed to his face and as suddenly receded, leaving it deathly pale. The looker-on in Grant thought how Danny Miller would have sneered at such an exhibition — Danny, who would kill a man and not bother to remember it. The Levantine was certainly an amateur at the game — a murderer by accident more than design, perhaps.

“I have brought you a visitor,” the minister was saying. “This is Mr. Grant. I found him fishing, but catching nothing, so I brought him in to get some hot tea. My sister, Mrs. Dinmont. My niece, Miss Dinmont. And a friend of ours, Mr. Lowe. Now, where will you sit?”

Grant was given a seat beside Miss Dinmont and facing Lamont. Lamont had bowed to him when introduced, but so far gave no sign of ill-meditated action. Either he was paralysed or he was going to take things quietly. And then as he sat down Grant saw the thing that made his heart leap. Lamont’s cup was on the wrong side of his plate. The man was left-handed.

“I am so glad you didn’t wait, Agnes,” Mr. Logan said in a tone which clearly said, I think you might have waited. “It was such a fine evening that I crossed by the swing bridge and came home by the other side of the river.”

“Well, we’re glad you did,” said his niece, “because you’ve brought Mr. Grant, and that makes an uneven number, and so we can put it to the vote. We’ve been having a fight as to whether a mixture of race in a person is a good thing or not. I don’t mean black and white, but just different stocks of white. Mother says that a single-stock person is the best, of course, but that is because she is solid Highland, back to the flood and before. Logans are Maclennans, you know, and there never was a Maclennan who hadn’t a boat of his own. But my father was a Borderer and my grandmother English, and Mr. Lowe’s grandmother was an Italian, so we are very firmly on the other side. Now, Uncle Robert is sure to side with Mother, being a pure-bred Highlander and having in a pure-bred degree all the stubbornness and stinking pride of his race. So we are looking to you for support. Do say that your ancestry is tartan.”

Grant said, quite honestly, that he thought a mixed strain of more value than a pure-bred one. That was, talking of purebred as it can exist today. It gave a man a many-sidedness instead of giving him a few qualities in excess, and that was a good thing. It tended to cleverness and versatility, and consequently broad-mindedness and wide sympathies. On the whole, he endorsed Miss Dinmont’s and Mr. — er — Lowe’s point of view.

In view of the lightness of the conversation Grant was astonished at the vehemence and seriousness with which Mr. Logan contradicted him. His race was a fetish with him, and he compared it at length with most of the other nations in western Europe, to their extreme detriment. It was only towards the end of tea that Grant found, to his intense amusement, that Mr. Logan had never been out of Scotland in his life. The despised Lowlanders he had met only during his training for the ministry some thirty years ago, and the other nations he had never known at all. Frustrated in his effort — nobly seconded by Miss Dinmont — to make light conversation, Grant played the part of a Greek chorus to Mr. Logan, and let his thoughts deal with Lamont.

The Levantine was beginning to look a little better. He met Grant’s eyes squarely, and except for the antagonism in his own, there was nothing remarkable about him. He made no attempt to hide the small scar on his thumb, though he must have known, as he knew about his telltale cup, that it was damning evidence. He had evidently decided that the game was up. It remained to be seen, though, whether he would come quietly when the time came. At least Grant was glad to see that flicker of antagonism in his eyes. It is an unlovely job to arrest a craven. A police officer would much sooner be hacked on the shins than clasped about the knees. There would quite obviously be no knee-clasping on this occasion.

One thing caused Grant’s heart to harden against the man: the strides he seemed to have made in Miss Dinmont’s regard in the three days of his stay. Even yet his quick smile came out to answer hers, and his eyes sought hers oftener than those of any one else at table. Miss Dinmont looked a girl who would be quite able to take care of herself — she had all a red-haired person’s shrewdness and capability — but that did not excuse Lamont’s lack of decent feeling. Had he merely been preparing an ally? A man on the run for murder does not usually have the spare interest for love-making — more especially if he is an amateur in crime. It was a blatant and heartless piece of opportunism. Well, he should have no chance of appealing to his ally; Grant would see to that. Meanwhile he kept his place in the conversation, and did justice to the fried trout which was the pièce de résistance of five-thirty tea at the manse. The Levantine ate, too, and Grant caught himself wondering what degree of effort was required to swallow each of these mouthfuls. Did he care, or had he got past that? Was his impudent “Don’t you think so, Mr. Grant?” a bluff or the real thing? His hands were quite steady — that thin, dark left hand that had put an end to his friend’s life — and he did not shirk his part in the conversation. There was obviously to the others no difference between the man who sat there now and the man who had sat there at lunch. The Levantine was doing it well.

At the end of tea, when they began to smoke, Grant offered Miss Dinmont a cigarette, and she raised her eyebrows in mock horror.

“My dear man,” she said, “this is a Highland manse. If you like to come out and sit on a stone by the river, I’ll have one, but not under this roof.”

The “under this roof’ was obviously a quotation, but her uncle pretended not to hear.

“There’s nothing I’d like better,” Grant said, “but it’s getting late, and as I am walking to Garnie, I think I’d better start. I’m so grateful to you all for the good ending to my day. Perhaps Mr. Lowe would walk a bit of the way with me? It’s early yet, and very fine.”

“Certainly,” said the Levantine, and preceded him into the hall. Grant’s adieux to his hostess were cut short by the fear that Lamont would have disappeared, but he found him in the hall calmly hoisting himself into the trench-coat he had worn that morning. And then Miss Dinmont came out to join her uncle, who was seeing them off the premises, and Grant had a sudden fear that she was going to offer to accompany them. Perhaps the resolute way in which Lamont kept his back turned to her daunted her a little. It would have been so natural for him to say, “Won’t you come along too?”

But he said nothing. Kept his back turned, though he knew she was there. That could only mean that he didn’t want her, and the suggestion she had been on the point of making died on her lips. Grant breathed again. He had no desire for a scene with a hysterical female, if it could be avoided. At the gate both men turned to acknowledge the presence of the two at the door. As Grant was replacing his battered hat he saw Lamont’s salutation. It was a mere doffing his cap and donning it again, but Grant had not known that any gesture could be so eloquent of farewell.

They walked in silence up the first slight ascent of road until they were well out of sight of the house, at the parting of the ways where the high road went up the hill and the track to the crofts branched off along the river. There Grant halted and said, “I think you know what I want you for, Lamont?”

“What exactly do you mean?” asked Lamont, facing him calmly.

“I am Inspector Grant from Scotland Yard, and I have a warrant for your arrest for the murder of Albert Sorrell in the Woffington queue on the night of the 13th. I must warn you that anything you say may be used in evidence against you. I want to see that you have nothing on you. Will you take your hands out of your pockets a moment and let me run you over?”

“You’ve made a mistake, Inspector,” the lean said. “I said I’d go a bit of the way with you, but I didn’t say how far. This is where I get off.” His left hand shot out of his pocket, and Grant, expecting a revolver, knocked his hand up as it lifted, but, even as his eyes closed instinctively, he saw and recognized the blue pepper-pot from the manse tea-table. Helpless, half blind, coughing and sneezing, he heard the man’s flying feet on the moor-track, and desperately tried to control himself so that he could hear the direction of the retreating sounds. But it was at least two minutes before he could see well enough to be able to follow. A remembrance of that evening in the Strand came to him, and he decided to take his time. No man, even as lightly built as the Levantine was, could run for more than a limited time. There was a radius of possibility bounded by the circumstance of exhaustion point. And judging by the direction he had chosen, when he reached that exhaustion point, the Levantine would be in a country that offered him little means of escape. And, of course, he would be shrewd enough to recognize that. Therefore, the more likely procedure would be that he should repeat the tactics of the Strand evening: lie hidden, probably till darkness made it safe to move, and then return to a better means of escape.

Well, Grant thought, the man who has the higher ground commands the situation. A few yards farther on, a small trickle of water came down the hillside. The valley it made was not deep enough to afford him cover standing up, but, if he bent, it hid his progress up the hillside from any one farther along the moor-tract. With as keen a scrutiny round him as his still smarting eyes would permit, he took to the small gully and, bent double, scrambled up it, stopping every few yards to make sure that nothing was in sight and that he himself was still in adequate cover. Farther up, the gully was bordered by stunted birch, and still farther up it ran through a small plateau thinly wooded with larger birch. Birch in its first mist of green is not ideal cover, but the plateau afforded a first-rate outlook, so Grant decided to risk it. Circumspectly he raised himself from the sandy bank of the stream to the fine turf of the plateau, and crawled across it to the fringe of thick heather that bordered a drop of several feet in the face of the hillside. From this vantage he had the whole immediate sweep of the valley before him, with the exception of a slab to his right, which was hidden by one of the rectangular patches of firwood so typical of the country. The sight of the firwood reassured him. The firwood would be to Lamont what the door on the other side of Bedford Street had been. He had not the faintest doubt that Lamont was lying there now, waiting for him to declare himself on the road somewhere. What puzzled him was what Lamont thought was going to take the place of the busses and the taxis. What hope had he other than the darkness? And he must realize that, if he waited till dark, Grant would have given the alarm. Already the light was beginning to go. Should he abandon his hiding-place and give the alarm, or was that the very thing that Lamont wanted? Would he be playing into Lamont’s hands now if he abandoned the watch and went back to raise beaters? He wished he could make up his mind — could see Lamont’s play. The more he thought of it, the surer he felt that Lamont was counting on his going back to give the alarm. It was the obvious thing to do. He had given Lamont his chance of going quietly, and he had not taken it, even though his resistance had meant the publication of his true standing; most assuredly, then, he would expect the inspector to be squeamish no longer about his or other people’s feelings, and to go back for help in his capture. That being so, Grant would stay where he was and keep an eye on the country.

For a long time he lay there in the dampish, withered heather, looking through the parted fronds at a tranquil strath. Once the brakes of a car squealed away to his left, where the high road came down the hill, and later he saw the car cross the bridge before the village, run like a small black spider along the road at the back of Carninnish House, and disappear up the coast road to the north. A sheep bleated far away on the hill, and a late lark sang high in the air, where the sun still was. But nothing moved in the valley but the river, and the slow northern twilight began to settle on it. And then something moved. Down by the river it was. Nothing more definite than the sudden flash of water in the river itself, there and gone again. But it was not the river; something had moved. Breathlessly he waited, his heart, pressed against the turf, beating time with the blood in his ears. He had to wait awhile, but what he saw he saw distinctly this time. From behind a huge twelve-foot boulder by the river his quarry slid into sight and disappeared again under the bank. Grant waited again patiently. Was he going to ground there, or was he making for somewhere? Even in his anxiety he was conscious of that amused indulgence with which a human being watches an unconscious wild animal busy about its own affairs — that “tickled” feeling that all human beings have when they are spying. And presently a gentle movement farther downstream advertised the fact that Lamont was not stationary. He was heading somewhere. And for a townsman he was making a wonderful job of cover. But then, of course, there had been the War — Grant had forgotten that Lamont was old enough to have seen active service. He probably knew all that was to be known about the art of taking cover. Grant had seen nothing that second time — he had merely been conscious of movement. He would probably have seen nothing the first time if there had been a better method of getting from that rock to the shelter of the bank than coming into the open. There was no further sign of movement, and Grant remembered that the left bank of the river would afford good shelter nearly all the way. It was time that he abandoned his seat on the dais and went down into the arena. What could Lamont’s plan be? If he held to his present course, he would be back at the manse in a quarter of an hour. Was that where he was making for? Was he going to take advantage of the tenderness he had aroused so farseeingly in the Dinmont girl? A pretty enough plan. If he, Grant, had done as Lamont had suspected, and gone back for help, the last place any one would look for him would be in the manse itself.

Grant swore, and let himself down the gully again as quickly as the going and his desire to remain in cover would allow. He regained the moor-track and hesitated, wondering which was the better plan. Between him and the river stretched a piece of moor, boulder-strewn certainly, but without cover for anything bigger than a rabbit. Only the firwood farther on had enabled Lamont to reach the river unobserved by him. Well, what about going back now and giving the alarm? And catch the man being hidden by the minister’s niece? asked the looker-on in him. Well, why not? he demanded angrily of himself: If she hides him, she deserves all that’s coming to her. But there’s no need for publicity even yet, urged his other half. Make sure it is to the manse he has gone, and then follow and arrest him there.

That seemed sensible enough, and Grant, hoping that no one as far down the river as Lamont was could see him, crossed the little moor to the river at the double. What he wanted was to cross the river. To follow the man down the river-bed was to court certain discovery. He did not want the man to run; he wanted him to go peacefully to ground in the manse, so that he could be pounced upon comfortably. If by any chance he could cross the river, he could keep an eye on the man’s progress from the high ground on the other side, could even move parallel with him, if he could come up with him, without the man’s being aware that he was being stalked. He looked at the torrent. Time was precious, and a wetting was nothing now. It is one thing to dip oneself in icy water in the cold blood of a high resolution and quite another to plunge into a flood in the heat of a chase. Grant chose a spot where the river was divided into three parts by two large boulders. If he could succeed in negotiating the first one, he could take the second and the bank in a flying leap, and it would not matter very much if he missed the bank as long as his hands caught at it. He would be across. He stepped back a pace or two and measured the distance to the first boulder with his eye. The first was the flatter of the two, and offered a landing-place; the second was pointed, and must be taken on the run. With an inarticulate prayer he launched himself into space, felt his nailed boots slip as they met the stone, recovered himself, felt the stone heeling over to the black pool beneath, leaped again, but knew even as he leaped that the slipping stone had lacked purchase for his spring, met the second stone sideways, and felt his hands on the far bank just in time to prevent himself going in farther than to his waist. Thankful and breathless, he pulled himself out, hastily wrung as much of the water from his heavy tweed trousers as would prevent him from being hampered by its weight, and made for the high ground beyond. Never had the moor appeared so treacherous. Dry tussocks of grass melted under his feet into bog, dead brambles clung with a living tenacity to his wet tweed, hidden branches of birch rose and hit him as he stepped on the nearer end, holes waited for his feet among the heather. It was more like a music-hall turn, he thought ferociously, than a serious attempt to overtake a criminal. Panting, he came to a turn of the river, and flung himself down to reconnoitre. There was his man, about fifty yards above the manse, moving very slowly and cautiously. It occurred to Grant that he, the pursuer, was having the rough time of it, while the pursued kept a pleasant and well-planned course in the open. Well, it wouldn’t be for long. The minute the man turned into that little back gate that they were laughing so serenely over this morning, he, Grant, would be out of the heather and doubling down the cart-track by the river as hard as he could go. He had a small automatic in his pocket and a pair of handcuffs, and this time he would use them — both if necessary. His man wasn’t armed or he wouldn’t have stolen the pepper-pot from the tea-table, but he wasn’t taking risks any longer. No one’s feelings would be considered any more in this case — his own least of all. Let every female from here to Land’s End have hysterics at once — he wouldn’t care.

Grant was still fuming and glowering and promising himself all sorts of fancy retributions when the man passed the gate. I have always wished that I could have seen Grant’s face at that moment — seen the disgruntled anger and resentment of a man who had tried to do things decently, only to have had his decency taken advantage of, change to the sheer unbelieving astonishment of a small boy beholding his first firework. He blinked hard, but the picture remained the same; what he saw was real. The man had passed the gate............
