"I'm sure of that, sir. But Mr. Robert has committed the additional folly, from his point of view, of letting us know why he was so desperately anxious to get back to London."

"But he didn't say a word!"

"Ah, words, idle words!

"Words are like leaves; and where they most abound
Much fruit of sense beneath is rarely found.

"It is actions that count, sir. Deeds, not words. Now, Mr. Robert has been kind enough to give us the eloquent facts, because he will be followed from the suburbs and his whereabouts watched most carefully."

"Dear me! I hadn't thought of that," said Hilton Fenley slowly. Two ideas were probably warring in his brain at that moment. One classed Furneaux as a garrulous idiot; the other suggested that there might be method in such folly.

"That's a clever simile of Pope's about dense leaves betokening scarcity of fruit," went on Furneaux. "Of course, it might be pushed too far. Think what a poisonous Dead Sea apple the Quarry Wood contained. Your father's murder might not have been possible today but for the cover given by the trees."

Fenley selected a dark overcoat and derby hat. He wore a black tie, but had made no other change in his costume.

"You are quite a literary detective, Mr. Furneaux," he commented.

"More literal than literary, sir. I have little leisure for reading, but I own an excellent memory. Nothing to boast of in that. It's indispensable in my profession."
