Hewitt examined the boots and shoes with great rapidity, but with a singularly quick eye for peculiarities.

“He liked a light shoe,” he said, “and he preferred to wear shoes rather than boots. There are few boots, and those not much worn, although he was living in the country. Trod square on the right foot, inward on the left, and wore the left heel more than the right. It’s plain he hated nails, for these are all hand-sewn, with scarcely as much as a peg visible in the lot; and they are all laced, boots and shoes alike. Come, this is the best-worn pair; it is also a pair of the same sort the maid tells me he must have been wearing, since they are missing; low shoes, laced; we’ll take them with us.”

We left the house and sought our friend the coachman. He pointed out quite clearly the path by which his master had gone on his last walk; showed us the gate, still fastened, over which he had climbed to gain the adjoining meadow, and put us in the way of finding the small wood and the barn.

Both within and without the gate there was a small patch bare of grass, worn by feet; and here Martin Hewitt picked up his trail at once.

“The ground has hardened since Thursday night,” he said; “and so much the better — it keeps the marks for us. Do you see what is here?”

There were footmarks, certainly, but so beaten and confused that I could make nothing of them. Hewitt’s practised eye, however, read them as I might have read a rather illegibly written letter.

“Here is the right foot, plain enough,” he said, carefully fitting the shoe he had brought in the mark. “He alighted on that as he came over the gate. Half over it is another footmark — Bowmore’s, I expect, for I can see signs of others, in both directions — going and coming. But we shall know better presently.”

He rose, and we followed the irregular track across the meadow. Like most such field-tracks, its direction was plainly indicated by the thin and beaten grass, with a bare spot here and there. Hewitt troubled to take no more than a glance at each of these spots as we passed, but that was all he needed. The meadow was bounded by a hedge, with a stile; and at the farther side of this stile my friend knelt again, with every sign of attention.

“A little piece of luck,” he reported. “The left shoe has picked up a tiny piece of broken thorn-twig just here. See the mark? The shoe was a little soddened in the sole by this time, and the thorn stuck. I hope it stuck altogether. If it did it may help us wonderfully when we get to the barn, for the trouble there will be the trampling all round of the people at the fire.”

So we went on till we reached the edge of the little wood. The field-path skirted this, and here Hewitt dropped on his knees and set to work with great minuteness.

“Keep away from the track, Brett,” he warned me, “or you may make it worse. The police have been here, I see, and quite recently, coming from the direction of Redfield. Here are two pairs of unmistakable police boots and another heavy pair with them; no doubt they brought the gamekeeper along with them, to have things fully explained.”

From the corner of the wood to a point forty yards along the path; back to the corner again, and then into the wood Hewitt went, carefully examining every inch of the ground as he did so. Then at last he rejoined me.

“I think the gamekeeper has told the truth,” he said. “It’s pretty plain, thanks to the soft ground hereabout, notwithstanding the policemen’s boots. Here they came together — the thorn-twig sticks to the shoe still, you see — and here they stopped. The marks face about, and Bowmore’s steps are retraced to the corner of the wood. Peytral’s turn again and go on, and Bowmore’s turn into the edge of the wood and come along among the trees. You don’t see them in the grassy parts quite as well as I do, I expect, but there they are. We’ll keep after Peytral’s prints. Bowmore’s come back in the same track, I see.”

The next stile led to Penn’s Meadow. This meadow — a large one — stretched over a rather steep hump of land, at the other side of which the barn stood. From the stile two paths could be discerned — one rising straight over the meadow in the direction of the barn, and the other skirting it to the left, parallel with the hedge.

“Here the footprints part,” Hewitt observed, musingly; “and what does that mean? Man[oe]uvring — or what?”

He thought a moment, and then went on: “We’ll leave the tracks for the present and see the barn. That is straight ahead, I take it.”

When we reached the top of the rise the barn came in view, a blackened and sinister wreck. The greater part of the main structure was still standing, and even part of the thatched roof still held its place, scorched and broken. Off to the right from where we stood the village roofs were visible, giving indication of the position of the road to Redfield. A single human figure was in sight — that of a policeman on guard before the barn.

“Now we must get rid of that excellent fellow,” said Hewitt, “or he’ll be offering objections to the examination I want to make. I wonder if he knows my name?”

We walked down to the barn, and Hewitt, assuming the largest possible air, addressed the policeman.

“Constable,” he said, “I am here officially — here is my card. Of course you will know the name if you have had any wide experience — London experience especially. I am looking into this case on behalf of Miss Peytral — co-operating with the police, of course. Where is your inspector?”

He was a rather stupid countryman, this policeman, but he was visibly impressed — even flurried — by Hewitt’s elaborate bumptiousness. He saluted, tried to look unnaturally sagacious, and confessed that he couldn’t exactly say where the inspector was, things being put about so just now. He might be in Throckham village, but more likely he was at Redfield.

“Ah!” Hewitt replied, with condescension. “Now, if he is in the village, you will oblige me, constable, by telling him that I am here. If he is not there, you will return at once. I will be responsible here till you come back. Don’t be very long, now.”

The man was taken by surprise, and possibly a trifle doubtful. But Hewitt was so extremely lofty and so very peremptory and official, that the inferior intelligence capitulated feebly, and presently, after another uneasy salute, the village policeman had vanished in the direction of the road. The moment he had disappeared Hewitt turned to the ruined barn. The door was gone, and the scorched and charred lumber that littered the place had a look of absolute ghostliness — perhaps chiefly the effect of my imagination in the knowledge of the ghastly tragedy that the place had witnessed. Well in from the doorway was a great scatter of light ashes — plainly the pea-straw that the coachman had spoken of. And by these ashes and partly among them, marked in some odd manner on the floor, was a horrible black shape that I shuddered to see, as Hewitt pointed it out with a moving forefinger, which he made to trace the figure of a prostrate human form.

“Did you never see that before in a burnt house?” Hewitt asked in a hushed voice. “I have, more than once. That sort of thing always leaves a strange stain under it, like a shadow.”

But business claimed Martin Hewitt, and he stepped carefully within. Scarcely had he done so, when he stood suddenly still, with a low whistle, pointing toward something lying among the dirt and ashes by the foot of that terrible shape.

“See?” he said. “Don’t disturb anything, but look!”

I crept in with all the care I could command, and stooped. The place was filled with such a vast confusion of lumber and cinder and ash that at first I failed to see at all what had so startled Hewitt’s attention. And even when I understood his direction, all I saw was about a dozen little wire loops, each a quarter of an inch long or less, lying among a little grey ash that clung about the ends of some of the loops in clots. Even as I looked another thing caught Hewitt’s eye. Among the straw-ashes there lay some cinders of paper and card, and near them another cinder, smaller, and plainly of some other substance. Hewitt took my walking-stick, and turned this cinder over. It broke apart a............
