"I understood it," smiled the inspector.

"Who saw this will?"

"There's no secret there. Its contents are common property, I should say. It was Mrs. Arnold, the sister-in-law, who dropped me the first hint; and Floyd himself has owned that his uncle made a will three weeks ago, cutting him down to $20,000."

"How did the professor come to postpone his will-making so long?"

"Satisfied, I suppose, with the laws of intestate descent."

"The other heir gets it all?"

"Harry Arnold? No. I believe some goes to charity, the servants and so on. A $10,000,000 cake will cut up into several neat slices, you know." But the thoughts of the district attorney seemed to move habitually on a higher plane.

"Floyd was a sister's son. Perhaps that is why the professor preferred him to his cousin," he said.

"A life-long preference which does not appear in his testament, however."

"But why did he cast him off at the eleventh hour?"
