Fenner grunted and followed the little man down the corridor. He stopped outside No. 47 and rapped three times fast and twice slowly on the door.

“Secret signs as well,” Fenner said admiringly.

The door opened and a short Cuban, dressed in a black suit, looked them over. Fenner shaped his lips for a whistle, but he didn’t make any sound.

Nightingale said in his soft voice: “It’s all right.”

The Cuban let them in. As he shut the door after them, Fenner saw a bulge in his hip-pocket. The hall they found themselves in was big, and three doors faced them.

“The boys in yet?” Nightingale asked.

The Cuban nodded. He sat down in an arm-chair by the front door and picked up a newspaper again. As far as he was concerned they weren’t there.

Nightingale went into the centre room. There were four men lounging about the room. They were all in shirt-sleeves and they all were smoking. Two of them were reading newspapers, one of them was listening to the radio, and the fourth was cleaning a rod. They all glanced at Nightingale, and then fixed wooden looks on Fenner.

The man with the rod got up slowly. “Who is it?” he said. He’d got a way of speaking with his teeth shut. He wore a white suit and a black shirt with a white tie. His wiry black hair was cropped close, and his yellow-green eyes were cold and suspicious.

Nightingale said, “This is Ross. From New York. Crotti knows him. He’s all right.” Then he turned to Fenner. “Meet Reiger.”
