Yellow — No work or meetings until specially notified.

LAMONT CRANSTON laughed. The matter of Volovick had troubled him during the past few days. Now he understood that the man was temporarily inactive.

The millionaire left the telephone room. When he arrived in the lobby of the club, the doorman accosted him.

“Note just came for you, Mr. Cranston.”

Mr. Cranston opened the envelope and read the message. It was from Prince Zuvor. It bore the letterhead of a New York hotel. Lamont Cranston read it at a glance.

I shall be unable to meet you at the club as I had hoped. I do not expect to be there until the end of the week. But I am at home to-night. If you choose to call, you are welcome. But remember -

The abrupt termination of the message was a reminder of the previous conversation, when Zuvor had mentioned the dangers which surrounded him. The note was signed “Richard Albion.”

Lamont Cranston left the Cobalt Club. He summoned a taxicab. He drove directly to the home of Prince Zuvor.

When he reached his destination, he stood looking at the house, from the street. He did not appear to notice a large sedan that was parked opposite the house. He went up the steps and rang the bell.

He was admitted by the Russian servant, who conducted him upstairs, as soon as he gave his name. He was ushered into the front room, where the wolfhound walked silently over to greet him.
