“I did go down to the promenade deck. And I’d hardly got there when a fellow who’s getting up the ship’s concert to-morrow night nobbled me to do something for it. I said I could only do conjuring tricks and juggling and so on, and he said all right, do conjuring tricks and juggling, then. He wanted to know if I knew anyone else who would help. I came up to ask you,” he said to Sam, “if you would do something.”

“No,” said Sam. “I won’t.”

“He’s got a man who’s going to lecture on deep-sea fish and a couple of women who both want to sing ‘The Rosary’ but he’s still a turn or two short. Sure you won’t rally round?”

“Quite sure.”

“Oh, all right.” Bream Mortimer hovered wistfully above them. “It’s a great morning, isn’t it?”

“Yes,” said Sam.

“Oh, Bream!” said Billie.

“Hello?”

“Do be a pet and go and talk to Jane Hubbard. I’m sure she must be feeling lonely. I left her all by herself down on the next deck.”

A look of alarm spread itself over Bream’s face.
