Mitchington shook his head.
“What’s it look like?” he answered, almost appealingly. “I put it to you, now!—what does it look like? Here’s this man been poisoned without a doubt—I’m certain of it. And—there were those rumours—it’s idle to deny that they centred in Ransford. And—this morning Ransford had the chance!”
“That’s arguing that Ransford purposely carried a dose of poison to put into Collishaw’s tin bottle!” said Bryce half-sneeringly. “Not very probable, you know, Mitchington.”
Mitchington spread out his hands.
“Well, there it is!” he said. “As I say, there’s no denying the suspicious look of it. If I were only certain that those rumours about what Collishaw hinted he could say had got to Ransford’s ears!—why, then—”
“What’s being done about that post-mortem?” asked Bryce.
“Dr. Coates and Dr. Everest are going to do it this afternoon,” replied Mitchington. “The Coroner went to them at once, as soon as I told him.”
“They’ll probably have to call in an expert from London,” said Bryce. “However, you can’t do anything definite, you know, until the result’s known. Don’t say anything of this to anybody. I’ll drop in at your place later and hear if Coates can say anything really certain.”
Mitchington went away, and Bryce spent the rest of the afternoon wondering, speculating and scheming. If Ransford had really got rid of this man who knew something—why, then, it was certainly Ransford who killed Braden.
He went round to the police-station at five o’clock. Mitchington drew him aside.
“Coates says there’s no doubt about it!” he whispered. “Poisoned! Hydrocyanic acid!”
Chapter XIII. Bryce is Asked a Question
Mitchington stepped aside into a private room, motioning Bryce to follow him. He carefully closed the door, and looking significantly at his companion, repeated his last words, with a shake of the head.
“Poisoned!—without the very least doubt,” he whispered. “Hydrocyanic acid—which, I understand, is the same thing as what’s commonly called prussic acid. They say then hadn’t the least difficulty in finding that out! so there you are.”
“That’s what Coates has told you, of course?” asked Bryce. “After the autopsy?”
“Both of ‘em told me—Coates, and Everest, who helped him,” replied Mitchington. “They said it was obvious from the very start. And—I say!”
“Well?” said Bryce.
“It wasn’t in that tin bottle, anyway,” remarked Mitchington, who was evidently greatly weighted with mystery.
“No!—of course it wasn’t!” affirmed Bryce. “Good Heavens, man—I know that!”
“How do you know?” asked Mitchington.
“Because I poured a few drops from that bottle into my hand when I first found Collishaw and tasted the stuff,” answered Bryce readily. “Cold tea! with too much sugar in it. There was no H.C.N. in that besides, wherever it is, there’s always a smell stronger or fainter—of bitter almonds. There was none about that bottle.”
“Yet you were very anxious that we should take care of the bottle?” observed Mitchington.
“Of course!—because I suspected the use of some much rarer poison than that,” retorted Bryce. “Pooh!—it’s a clumsy way of poisoning anybody!—quick though it is.”
“Well, there’s where it is!” said Mitchington. “That’ll be the medical evidence at the inquest, anyway. That’s how it was done. And the question now is—”
“Who did it?” interrupted Bryce. “Precisely! Well—I’ll say this much at once, Mitchington. Whoever did it was either a big bungler—or damned clever! That’s what I say!”
“I don’t understand you,” said Mitchington.
“Plain enough—my meaning,” replied Bryce, smiling. “To finish anybody with that stuff is easy enough—but no poison is more easily detected. It’s an amateurish way of poisoning anybody—unless you can do it in such a fashion that no suspicion can attach you to. And in this case it’s here—whoever administered that poison to Collishaw must have been certain—absolutely certain, mind you!—that it was impossible for any one to find out that he’d done so. Therefore, I say what I said—the man must be damned clever. Otherwise, he’d be found out pretty quick. And all that puzzles me is—how was it administered?”
“How much would kill anybody—pretty quick?” asked Mitchington.
“How much? One drop would cause instantaneous death!” answered Bryce. “Cause paralysis of the heart, there and then, instantly!”
Mitchington remained silent awhile, looking meditatively at Bryce. Then he turned to a locked drawer, produced a key, and took something out of the drawer—a small object, wrapped in paper.
“I’m telling you a good deal, doctor,” he said. “But as you know so much already, I’ll tell you a bit more. Look at this!”
He opened his hand and showed Bryce a small cardboard pill-box, across the face of which a few words were written—One after meals—Mr. Collishaw.
“Whose handwriting’s that?” demanded Mitchington.
Bryce looked closer, and started.
“Ransford’s!” he muttered. “Ransford—of course!”
“That box was in Collishaw’s waistcoat pocket,” said Mitchington. “There are pills inside it, now. See!” He took off the lid of the box and revealed four sugar-coated pills. “It wouldn’t hold more than six, this,” he observed.
Bryce extracted a pill and put his nose to it, after scratching a little of the sugar coating away.
“Mere digestive pills,” he announced.
“Could—it!—have been given in one of these?” asked Mitchington.
“Possible,” replied Bryce. He stood thinking for a moment. “Have you shown those things to Coates and Everest?” he asked at last.
“Not yet,” replied Mitchington. “I wanted to find out, first, if Ransford gave this box to Collishaw, and when. I’m going to Collishaw’s house presently—I’ve certain inquiries to make. His widow’ll know about these pills.”
“You’re suspecting Ransford,” said Bryce. “That’s certain!”
Mitchington carefully put away the pill-box and relocked the drawer.
“I’ve got some decidedly uncomfortable ideas—which I’d much rather not have—about Dr. Ransford,” he said. “When one thing seems to fit into another, what is one to think. If I were certain that that rumour which spread, about Collishaw’s knowledge of something—you know, had got to Ransford’s ears—why, I should say it looked very much as if Ransford wanted to stop Collishaw’s tongue for good before it could say more—and next time, perhaps, something definite. If men once begin to hint that they know something, they don’t stop at hinting. Collishaw might have spoken plainly before long—to us!”
Bryce asked a question about the holding of the inquest and went away. And after thinking things over, he turned in the direction of the Cathedral, and made his way through the Cloisters to the Close. He was going to make another move in his own game, while there was a good chance. Everything at this juncture was throwing excellent cards into his
