“Well,” admitted Bryce, “honestly, I can't say that I have. But I can see what theory there might be. This—that Ransford was the man who deceived Brake, that he ran away with Brake's wife, that she's dead, and that he's brought up the children in ignorance of all that—and therefore—”

“And therefore,” interrupted Harker with a smile, “that when he and Brake met—as you seem to think they did—Ransford flung Brake through that open doorway; that Collishaw witnessed it, that Ransford's found out about Collishaw, and that Collishaw has been poisoned by Ransford. Eh?”

“That's a theory that seems to be supported by facts,” said Bryce.

“It's a theory that would doubtless suit men like Mitchington,” said the old detective, with another smile. “But—not me, sir! Mind you, I don't say there isn't something in it—there's doubtless a lot. But—the mystery's a lot thicker than just that. And Brake didn't come here to find Ransford. He came because of the secret in that scrap of paper. And as you've got it, doctor—out with it!”

Bryce saw no reason for concealment and producing the scrap of paper laid it on the table between himself and his host. Harker peered inquisitively at it.

“Latin!” he said. “You can read it, of course. What does it say?”

Bryce repeated a literal translation.

“I've found the place,” he added. “I found it this morning. Now, what do you suppose this means?”

Harker was looking hard at the two lines of writing.

“That's a big question, doctor,” he answered. “But I'll go so far as to say this—when we've found out what it does mean, we shall know a lot more than we know now!”
