The audience listened with good-humoured attention, and for a moment Mr. Jennings stood motionless, still smiling pleasantly. The little buzz of conversation which usually sprang up between the items had not yet begun, and save for the faint, all-pervading murmur of the engines, the gently swaying saloon was momentarily still. Then through the silence came a slight though unexpected sound. Miss da Silva’s handbag had slipped off her knee, and the metal hasp had struck the parquet floor with a sharp tap.
French glanced at her face with a sudden thrill. It had gone a queer shade of yellowish brown, and her hand, hanging down by her side, was clenched till the knuckles showed the same livid brownish hue. She evidently had not noticed her bag fall, and in her fixed and staring eyes there grew the shadow of a terrible fear. No one but French seemed to have noticed her emotion, and a man beside her stooped to pick up the bag. At the same time the silence was broken by a stout, military-looking old gentleman, who with some “Ha, ha’s!” and “Be Gad’s!” adjured the company to set about solving the puzzle, and conversation became general. Miss da Silva rose quietly and moved rather unsteadily towards the door.
For French to get up and open the door for her was an act of common politeness. With a slight bow he held it as she passed through, then following her immediately, he closed it behind him.
They were alone in the passage leading to the companion-way, and as he glanced keenly at her face he felt no further doubt. Disguised by some adroit alterations to hair and eyebrows, and, he believed, with a differently-shaped set of false teeth, a darkened complexion and glasses, there stood before him the original of the photographs. He laid his hand on her arm.
“Miss Winter,” he said gravely, “I am Inspector French of Scotland Yard. I arrest you on a charge of being concerned in the murder of Charles Gething and the theft of precious stones and money from Messrs. Duke & Peabody’s on the 25th of November last.”
The woman did not reply, but like a flash her free arm went to her mouth. French grasped wildly and caught it. She gulped, and at the same moment reeled. French, himself trembling and with beads of perspiration on his forehead, laid her gently on the floor, where she lay unconscious. He hastily stepped back into the saloon, and moved quietly to where he had seen the ship’s doctor sitting, whispered in his ear. Sergeant Carter got up at the same moment, and a second later the two detectives stood looking down with troubled faces, while Dr. Sandiford knelt beside the motionless figure on the floor.
“Good God!” he cried at once, “she’s dead!” He put his nose to her lips. “Prussic acid!” He gazed up at his companions with a countenance of horrified surprise.
“Yes; suicide,” said French shortly. “Get her moved to my cabin before any one comes.”
The doctor, ignorant of the circumstances, looked at the other with a sudden suspicion, but on French’s hurried explanation he nodded, and the three men bore the still form off and laid it reverently on the sofa in the Inspector’s stateroom.
“When you’ve examined her, tell the Captain,” French said. “Meantime Carter and I must go and arrest the poor creature’s husband. You might show me his cabin when you’re through.”
