He began to look vague again, and his fingers went yearningly towards the dahlia. I could see he wanted to be left alone, to let his brain sleep in the peaceful contemplation of his flowers, not to be worried by a husky like me who was taking up his time for nothing.

“He runs one of those crank sanatoriums, right next door to the Crosby estate,” he said finally. “He’s a friend of the family. His position is such he couldn’t ethically issue a certificate. He is not a qualified practitioner. I was very flattered they asked for my help.”

“Why, no,” he said, and alarm again flickered in the dim eyes. “I arrived about half an hour after she was dead. She had died in her sleep. The symptoms were unmistakable.

He nodded, getting more worried every second.

“Miss Crosby. The younger one. She was there.”

“Maureen?”
