“Fifteen thousand bucks,” Maurer said in a voice scarcely above a whisper.

McCann drew in a slow deep breath. He slid the envelope into his hip pocket.

“Perhaps I can return the favour,” he said woodenly.

“Well, yes,” Maurer said, and moved over to the empty fireplace. “I should like to be the first to know where Miss Coleman is to be found. Could that be arranged?”

McCann became aware that sweat was running down his face.

“She may not have seen anything,” he said thickly. “The chances are she didn’t. Miss Arnot wouldn’t have let her come up to the house. She probably left her name and then went away.”

“Could it be arranged?” Maurer repeated.

“I guess so. I’ve told my men to report direct to me as soon as they have found her, and to take no action until I give instructions. I’ve promised to contact the D.A.’s office. They want to see her: they’ll take charge of her.”

’I think I should see her first. When you have found her address, please telephone here. Louis will be waiting.”

“The D.A. will be waiting too,” McCann said quietly. “I have to be careful about this, Mr. Maurer. There mustn’t be much of a time lag. I can’t give you more than half an hour.”
