"Do you mean that the Home Secretary has sanctioned the breaking off of this inquiry."

"In the conditions—"

"Because, if that is what your words imply, Mr. Forbes, I may tell you at once that I don't believe you. It is more than any Home Secretary dare do, and if you harbor any lingering doubts on the point, go to Mr. Theydon's telephone, ring up the Home Office, and tell the gentleman at the other end of the wire exactly what I have said. Of course you really don't mean anything of the sort. By virtue of some special and inside knowledge of certain facts communicated to the Home Secretary, you may have persuaded him to promise that, provided the ends of justice are not defeated thereby, every precaution will be taken to keep the main lines of the inquiry secret until the whole position can be laid before the law officers of the Crown. The Home Secretary may have gone that far, Mr. Forbes, but not one inch farther, and you know it."

The two antagonists, so singularly disproportionate in size, were yet so perfectly matched in the vastly more important qualities of brain and nerve that the contest lost all sense of inequality. Theydon felt himself of no account in this duel. He was like an urchin watching open-mouthed a combat of gladiators.

Forbes, not without a perceptible effort, choked down his wrath and recovered his poise.

"You have gaged the state of affairs accurately enough," he said, speaking more calmly. "May I, then, recommend you to consult your direct superiors before carrying your investigations any furthur, Mr.—"

"Furneaux—Charles Francois Furneaux."

"Just so, Mr. Charles Francois Furneaux."

"I give you my full name, because one of the peculiar features of this case is the inability of some persons mixed up in it to recall names, or even the mere salient facts," and the detective's glance dwelt for an instant on Theydon, who, again, in his own estimation, shrank into the boots of a fourth-form boy detected by a master in an overt breach of college rules.

But the little man was speaking impressively, and, Theydon compelled his wandering wits to pay attention.
