There’s many a weary game to be played  
With never a penny to choose,
 
But the weariest game in all the world
 
Is waiting for dead men’s shoes.
 
It was about a week later that Edward Mottisfont rang David Blake up on the telephone and begged him in accents, to come to Mr. Mottisfont without delay.
 
“It’s another attack—a very bad one,” said Edward in the hall. His voice shook a little, and he seemed very nervous. David thought it was certainly a bad attack. He also thought it a strange one. The old man was in great pain, and very ill. Elizabeth Chantrey was in the room, but after a glance at his patient, David sent her away. As she went she made a movement to take up an empty cup which stood on the small table beside the bed, and old Mr. Edward Mottisfont fairly snapped at her.
 
“Leave it, will you—I’ve stopped Edward taking it twice. Leave it, I say!”
 
Elizabeth went out without a word, and Mr. Mottisfont caught David’s wrist in a shaky grip.
 
“D’ you know why I wouldn’t let her take that cup? D’ you know why?”
 
“No, sir——”
 
Old Mr. Mottisfont’s voice dropped to a thread. He was panting a little.
 
“I was all right till I drank that damned tea, David,” he said, “and Edward brought it to me—Edward——”
 
“Come, sir—come—” said David gently. He was really fond of this queer old man, and he was for him.
 
“David, you won’t let him give me things—you’ll look to it. Look in the cup. I wouldn’t let ’em take the cup—there’s dregs. Look at ’em, David.”
 
 
David took up the cup and walked to the window. About a tablespoonful of cold tea remained. David the cup, then became suddenly . That small remainder of cold tea with the little skim of cream upon it had suddenly become of absorbing interest. David tilted the cup still more. The tea made a little pool on one side of it, and all across the bottom of the cup a thick white drained slowly down into the pool. It was such a sediment as is left by very chalky water. But all the water of Market Harford is as soft as rain-water. It is not only chalk that makes a sediment like that. makes one, too. David put down the cup quickly. He opened the door and went out into the passage. From the far end Elizabeth Chantrey came to meet him, and he gave her a hastily note for the chemist, and asked her for one or two things that were in the house. When he came back into Mr. Mottisfont’s room he went straight to the wash-stand, took up a small glass bottle labelled ipecacuanha wine and spent two or three minutes in washing it . Then he poured into it very carefully the contents of the cup. He did all this in total silence, and in a very quiet and business-like manner.
 
Old Mr. Edward Mottisfont lay on his right side and watched him. His face was twisted with pain, and there was a dampness upon his brow, but his eyes followed every motion that David made and every look upon his face. They were intent—alive—observant. Whilst David stood by the wash-stand, with his back towards the bed, old Mr. Edward Mottisfont’s lips twisted themselves into an odd smile. A gleam of humour danced for a moment in the watching eyes. When David put down the bottle and came over to the bed, the gleam was gone, and there was only pain—great pain—in the old, restless face. There was a knock at the door, and Elizabeth Chantrey came in.
 
Three hours later David Blake came out of the room that faced old Mr. Mottisfont’s at the farther end of the corridor. It was a long, low room, fitted up as a laboratory—very well and fitted up—for the old man had for years found his greatest pleasure and in experimenting with chemicals. Some of his experiments he to David, but the majority he kept carefully to himself. They were of a somewhat curious nature. David Blake came out of the laboratory with a very stern look upon his face. As he went down the stair he met with Edward Mottisfont coming up. The sternness . Edward looked an unspoken question, and then without a word turned and went down before David into the hall. Then he waited.
 
“Gone?” he said in a sort of whisper, and David his head.
 
He was remembering that it was only a week since he had told Edward in this very spot that his uncle might live for three years. Well, he was dead now. The old man was dead now—out of the way—some one had seen to that. Who? David could still hear Edward Mottisfont’s voice asking, “How long is he likely to live?” and his own answer, “Perhaps three years.”
 
“Come in here,” said Edward Mottisfont. He opened the dining-room door as he , and David followed him into a dark, old-fashioned room, separated from the one behind it by folding-doors. One of the doors stood open about an inch, but there was only one lamp in the room, and neither of the two men paid any attention to such a circumstance.
 
Edward sat down by the table, which was laid for dinner. Even above the white his face was noticeably white. All his life this old man had been his bugbear. He had hated him, not with the hot which springs from one great sudden wrong, but with the cold slow bred of a thousand trifling oppressions. He had looked forward to his death. For years he had thought to himself, “Well, he can’t live for ever.” But now that the old man was dead, and the lifted from his neck, he felt no relief—no sense of freedom. He felt oddly shocked.
 
 
David Blake did not sit down. He stood at the opposite side of the table and looked at Edward. From where he stood he could see first the white tablecloth, then Edward’s face, and on the wall behind Edward, a full-length portrait of old Edward Mottisfont at the age of thirty. It was the work of a young man whom Market Harford had looked upon as a very disreputable young man. He had since become so famous that they had a tablet to the front of the house in which he had once lived. The portrait was one of the best he had ever painted, and the eyes, Edward Mottisfont’s black, eyes, looked down from the wall at his nephew, and at David Blake. Neither of the men had spoken since they entered the room, but they were both so busy with their thoughts that neither noticed how silent the other was.
 
At last David spoke. He said in a hard level voice:
 
“Edward, I can’t sign the certificate. There will have to be an inquest.”
 
Edward Mottisfont looked up with a great start.
 
“An inquest?” he said, “an inquest?”
 
One of David’s hands rested on the table. “I can’t sign the certificate,” he repeated.
 
Edward stared at him.
 
“Why not?” he said. “I don’t understand——”
 
“Don’t you?” said David Blake.
 
Edward up his hair in a distracted fashion.
 
“I don’t understand,” he repeated. “An inquest? Why, you’ve been attending him all these months, and you said he might die at any time. You said it only the other day. I don’t understand——”
 
“Nor do I,” said David .
 
Edward stared again.
 
“What do you mean?”
 
“Mr. Mottisfont might have lived for some time,” said David Blake, speaking slowly. “I was attending him for a illness, which would have killed him sooner or later. But it didn’t kill him. It didn’t have a chance. He died of poisoning—arsenic poisoning.”
 
One of Edward’s hands was lying on the table. His whole arm , and the hand fell over, palm . The fingers opened and closed slowly. David found himself staring at that slowly moving hand.
 
 
“Impossible,” said Edward, and his breath caught in his throat as he said it.
 
“I’m afraid not.”
 
Edward leaned forward a little.
 
“But, David,” he said, “it’s not possible. Who—who do you think—who would do such a thing? Or—suicide—do you think he committed suicide?”
 
David drew himself suddenly away from the table. All at once the feeling had come to him that he could no longer touch what Edward touched.
 
“No, I don’t think it was suicide,” he said. “But of course it’s not my business to think at all. I shall give my evidence, and there, as far as I am concerned, the matter ends.”
 
Edward looked helplessly at David.
 
“Evidence?” he repeated.
 
“At the inquest,” said David Blake.
 
“I don’t understand,” said Edward again. He put his head in his hands, and seemed to be thinking.
 
“Are you sure?” he said at last. “I don’t see how—it was an attack—just like his other attacks—and then he died—you always said he might die in one of those attacks.”
 
There was a sort of trembling eagerness in Edward’s tone. A feeling of swept over David. The scene had become intolerable.
 
“Mr. Mottisfont died because he drank a cup of tea which contained enough arsenic to kill a man in health,” he said sharply.
 
He looked once at Edward, saw him start, and added, “and I think that you brought him that tea.”
 
“Yes,” said Edward. “He asked me for it, how could there be arsenic in it?”
 
“There was,” said David Blake.
 
“Arsenic? But I brought him the tea——”
 
“Yes, you brought him the tea.”
 
Edward lifted his head. His eyes behind his glasses had a and bewildered look. His voice shook a little.
 
“But—if there’s an inquest—they might say—they might think——”
 
He pushed his chair back a little way, and half rose from it, resting his hands on the table, and peering across it.
 
“David, why do you look at me like that?”
 
David Blake turned away.
 
 
“It’s none of my business,” he said, “I’ve got to give my evidence, and for God’s sake, Edward, pull yourself together before the inquest, and get decent legal advice, for you’ll need it.”
 
Edward was shockingly pale.
 
“You mean—what do you mean? That people will think—it’s impossible.”
 
David went towards the door. His face was like a flint.
 
“I mean this,” he said. “Mr. Mottisfont died of arsenic poisoning. The arsenic was in a cup of tea which he drank. You brought him the tea. You are in a very serious position. There will have to be an inquest.”
 
Edward had risen completely. He made a step towards David.
 
“But if you were to sign the certificate—there wouldn’t need to be an inquest—David——”
 
“But I’m damned if I’ll sign the certificate,” said David Blake.
 
He went out and shut the door sharply behind him.
