Can you tell me if you have heard any noises or voices during the last half-hour ?" The man shook his head.
"We have heard nothing, sir," he said.
"Who lives here ?" Tavernake asked.
"Did you call me up at one o'clock in the morning to ask silly questions ?" the man replied insolently.

"Every one's in bed here and I was just going." "There's a light in your ground floor room," Tavernake remarked.
"There's some one talking there now--I can hear voices." The man closed the door in his face.

For some time Tavernake wandered restlessly about, starting at last reluctantly homewards.

He had reached the Strand and was crossing Trafalgar Square when a sudden thought held him.

He stood still for a moment in the middle of the street.
