I laughed, and admitted that The Clue of Crimson was at present engaging my sole attention. Poirot shook his head sadly.

"But replace then the others on the bookshelf! Never, never shall I see you embrace the order and the method. Mon Dieu, what then is a bookshelf for?"

I apologised humbly, and Poirot, after replacing the offending volumes, each in its appointed place, went out and left me to uninterrupted enjoyment of my selected book.

I must admit, however, that I was half asleep when Mrs. Pearson's knock at the door aroused me.

"A telegram for you, captain."

I tore the orange envelope open without much interest.

Then I sat as though turned to stone.

It was a cable from Bronsen, my manager out at the South American ranch, and it ran as follows:—

"Mrs. Hastings disappeared yesterday, feared been kidnapped by some gang calling itself big four cable instructions have notified police but no clue as yet."

Bronsen.
