"What's the matter with him, Doctor?" he asked, looking up at Thorndyke. "Is it apoplexy? Or is it a heart attack, think you?"
Thorndyke shook his head, though he stooped and put his fingers on the unconscious man's wrist.
"Prussic acid or potassium cyanide is what the appearances suggest," he replied.
"But can't you do anything?" demanded the inspector.
Thorndyke dropped the arm, which fell limply to the floor.
"You can't do much for a dead man," he said.
"Dead! Then he has slipped through our fingers after all!"
"He has anticipated the sentence. That is all." Thorndyke spoke in an even, impassive tone which struck me as rather strange, considering the suddenness of the tragedy, as did also the complete absence of surprize in his manner. He seemed to treat the occurrence as a perfectly natural one.
Not so Inspector Badger; who rose to his feet and stood with his hands thrust into his pockets scowling sullenly down at the dead lawyer.
"I was an infernal fool to agree to his blasted conditions," he growled savagely.
"Nonsense," said Thorndyke. "If you had broken in you would have found a dead man. As it was you found a live man and obtained an important statement. You acted quite properly."
"How do you suppose he managed it?" asked Badger.
"Let us look at his cigarette case," said he.
Badger extracted the little silver case from the dead man's pocket and opened it. There were five cigarettes in it, two of which were plain, while the other three were gold-tipped. Thorndyke took out one of each kind and gently pinched their ends. The gold-tipped one he returned; the plain one he tore through, about a quarter of an inch from the end; when two little black tabloids dropped out on to the table. Badger eagerly picked one up and was about to smell it when Thorndyke grasped his wrist. "Be careful," said he; and when he had cautiously sniffed at the tabloid--held at a safe distance from his nose--he added: "Yes, potassium cyanide. I thought so when his lips turned that queer color. It was in that last cigarette; you can see that he has bitten the end off."
For some time we stood silently looking down at the still form stretched on the floor. Presently Badger looked up.
"As you pass the porter's lodge on your way out," said he, "you might just drop in and tell him to send a constable to me."
