"Where did they get it ?" The Inspector shook his head.

"Of course, that's just the puzzle, my lord.

I'm afraid we shall have to leave that to the Scotland Yard man." As he spoke, he took out his whistle and blew sharply on it.

A constable came to the door and saluted.
"Got your men placed, Brown ?" asked the Inspector.

"Just put another man on the drive, and give him orders that no man is to enter the lodge gates excepting the detective, when he comes." "What's that for ?" asked Heyton, as if the question were inspired by his desire to understand everything that was being done.
"I don't want a lot of people tramping over the place," said the Inspector, rather evasively.
"Oh, ah, yes," said Heyton.
