Bert never doubted that she was dead, and he felt a glow of satisfaction stealing over him at the knowledge. There were great livid marks on her neck where his convulsive fingers had clutched at it, and he stooped over her and looked at them with a gratified smile. They were already turning black.
A slight noise in the next room brought him to his senses.
He crept on tiptoe to the door and listened intently with his ear to it. The sounds in the next room continued, some one seemed to be opening and shutting drawers; but there was no movement in the passage, and after a moment he opened the door cautiously and went out.
No one was in sight, and as an afterthought he went back, and removing the key locked the door on the outside, as silently as he had opened it. Then putting the key in his pocket he ran down the stairs. The page who had shown him up was idling in the hall, but no one else was about, though he caught a glimpse of a seated figure in the bureau as he passed. Forcing himself to pause as he passed the page, he said to him:
“Mrs. Vanderstein has asked me to tell you that she has a headache, and does not wish to be disturbed again to-day. Do you understand?”
“Yes, sir. I will give the message at the bureau. They will tell the waiter and chambermaid.”
The page spoke English perfectly, and Bert felt assured that he would do his errand. To make sure, he repeated his injunction and gave the boy a shilling to impress it on his memory. Then he walked down the steps with every outward appearance of calm.
His impulse was to go back towards the harbour, but as a precaution he started off in the opposite direction and only approached the docks after several turnings separated him from the sea-front. There was no boat back to England, however, till past seven, and he hung about the port for three whole hours that seemed like three centuries. In a quiet corner behind some empty trucks he got rid of his black beard, and applying a match to it saw it frizzle up and disappear in two or three seconds. He ground the ashes into the earth with his heel, and with a recklessness which surprised himself walked back past the doorway of the Hôtel de Douvres, to see if he would be known. The page was still lolling in the doorway, and, to Bert’s satisfaction, stared at him as he passed with a vacant eye. He felt certain he had not been recognised, and went back to the harbour with a lighter heart.
There he watched the steamer from Folkestone arrive and disembark her passengers, among whom—though he did not know it—was the man sent by the London police to interview Mrs. Vanderstein; and a few minutes later it was time to go on board the boat, which took him back to England.
The next morning found him back in his place at the house agents’ office, and as the day passed without event he began to feel a sense of security to which he had lately been a stranger. After all, he had passed hours in the company of London’s greatest detective without arousing any suspicion; and every hour, he believed, added to his safety.
