“Locked up in the desk in the boudoir, they found a will of Mrs. Inglethorp’s, dated before her marriage, leaving her fortune to Alfred Inglethorp. It must have been made just at the time they were engaged. It came quite as a surprise to Wells⁠—and to John Cavendish also. It was written on one of those printed will forms, and witnessed by two of the servants⁠—not Dorcas.”

“Did Mr. Inglethorp know of it?”

“He says not.”

“One might take that with a grain of salt,” I remarked sceptically. “All these wills are very confusing. Tell me, how did those scribbled words on the envelope help you to discover that a will was made yesterday afternoon?”

Poirot smiled.
