“If you want it in a single word,” Roger said, not without a certain reluctance, “Jefferson.”

Jefferson?” Alec exclaimed. “Oh, rot!”

Roger glanced at him curiously. “Now that’s interesting,” he commented. “Why do you say ‘rot’ like that?”

“Because——” Alec hesitated. “Oh, I don’t know. It seems such rot to think of Jefferson committing a murder, I suppose. Why?”

“You mean, you don’t think it’s the sort of thing he would do?”

“I certainly don’t!” Alec returned with emphasis.

“Do you know, Alec, I’m beginning to think you’re a better judge of character than I am. It’s a humiliating confession, but there you are. Tell me, have you always thought that about Jefferson, or only just recently?”

Alec considered. “Ever since this business cropped up, I think. It always seemed fantastic to me that Jefferson could be mixed up with it. And the two women as well, for that matter. No, Roger, if you’re trying to fix it on Jefferson, I’m quite sure you’re making a bad mistake.”

Roger’s complacency was unshaken.

“If the case were an ordinary one, no doubt,” he replied. “But you’ve got to remember that this isn’t. Stanworth was a blackmailer, and that alters everything. You may murder an ordinary man, but you execute a blackmailer. That is, if you don’t kill him on the spur of the moment, carried away by madness or exasperation. You’d do that sort of thing on your own account, wouldn’t you? Well, how much more so are you going to do it on behalf of a woman, and that a woman with whom you’re in love? I tell you, Alec, the whole thing is as plain as a pikestaff.”
