Maurice Leblanc,
813 — Chapter 1: The Tragedy at the Palace Hotel
(1910)
“ CHAPTER I. THE TRAGEDY AT THE PALACE HOTEL MR. KESSELBACH stopped short on the threshold of the sitting-room, took his secretary's arm and, in an anxious voice, whispered:"Chapman, some one has been here again.""Surely not, sir," protested the secretary. "You have just opened the hall-door yourself; and the key never left your pocket while we were lunching in the restaurant.""Chapman, some one has been here again," Mr. Kesselbach repeated. He pointed to a traveling-bag on the mantelpiece. "Look, I can prove it. That bag was shut. It is now open." ”
