Callaghan got up.
"I'm sorry I can't be of more use to you, Gringall," he said. "You know I'd like to be."
Gringall got up. They stood smiling at each other.
Gringall said: "What are you going to do now, that is supposing Mrs. Wilbery asks you to find Lionel? Have you got a plan of campaign?"
Callaghan grinned.
"That's my business," he said. "I never discuss my client s affairs with police officers."
Gringall said: "You're a hard case, Slim." He held out his hand. "Come in and see me sometime."
"I'm looking forward to it," said Callaghan.
He went to the door, opened it; then he turned with his hand on the doorknob.
"By the way," he said, "you wouldn't have change for a hundred pound note, would you?"
"Thanks for the compliment," said Gringall, "but they don't pay us enough."
