"Number 12," the manager answered. "I can't do anything for you, though, Charlie," he added. "I'd do anything I could, but they have given special orders that no one is to interrupt them, and they decline to be interviewed by or communicate with any strangers."

"I shall see the thing out, nevertheless," my friend announced.

"And I," I answered. "Let's have lunch together. Is there a smart boy in the place who could let us know directly any one leaves the sitting-room?"

The manager smiled.

"Mr. Sinclair knows all about that, sir," he said, pointing to my friend. "I have nothing to say about it, of course."

Sinclair left the room for a minute or two. When he came back he nodded confidentially.

"I have a boy watching the door," he said. "The moment any one leaves we shall hear of it."

We went into the restaurant and ordered lunch. In about half an hour a small boy came hastily in and addressed Sinclair.

"They have ordered luncheon up in the sitting-room, sir," he said. "I thought I'd better let you know."

"For how many?" Sinclair asked quickly.
