detected the presence of someone lurking in the neighbourhood of the
house?"

"Before it."

"And the burglarious entrance?"

"That took place rather less than a month ago. On the eve of the full
moon."

Paul Harley stood up and relighted his pipe.

"There are quite a number of other details, Colonel," he said, "which I
shall require you to place in my possession. Since I have determined to
visit Cray's Folly, these can wait until my arrival. I particularly
refer to a remark concerning a neighbour of yours in Surrey."

Colonel Menendez nodded, twirling his cigarette between his long,
yellow fingers.

"It is a delicate matter, gentlemen," he confessed.

"I must take time to consider how I shall place it before you. But I
may count upon your arrival tomorrow?"

"Certainly. I am looking forward to the visit with keen interest."

"It is important," declared our visitor; "for on Wednesday is the full
moon, and the full moon is in some way associated with the sacrificial
rites of Voodoo."
