"Yes," he concurred; "but if Sullivan had tried to get a conviction on your so-called psychological theories, he'd have been adjudged insane."
"Doubtless," sighed Vance. "You illuminati of the law would have little to do if you went about your business intelligently."
"Theoretically," replied Markham at length, "your theories are clear enough; but I'm afraid I've dealt too long with material facts to forsake them for psychology and art. . . . However," he added lightly, "if my legal evidence should fail me in the future, may I call on you for assistance?"
"I'm always at your service, old chap, don't y' know," Vance rejoined. "I rather fancy, though, that it's when your legal evidence is leading you irresistibly to your victim that you'll need me most, what?"
And the remark, though intended merely as a good-natured sally, proved strangely prophetic.
