As he sat in the tube on his way back to the Yard, he was conscious of some misgivings as to the way in which he had handled the interview. He had done his best to make it easy for Miss Duke. This was, of course, the natural and the kindly thing to do, but was it his duty? Should he not rather have used the news as a lever to startle some admission out of the girl which would have given him the information which he suspected she possessed. If he had allowed a promising clue to slip he had neglected his duty and injured himself. And his chief was no fool. He would unfailingly see the possibility and ask what use had been made of it. But though French felt thus a trifle uneasy, he could not bring himself to regret his course of action. He was not only a man of natural kindliness of heart, but he had the gift of imagination. He saw himself in the girl’s place, and was glad he had not added to her trouble. Next morning the report came from Holland, together with Miss Duke’s letter. The former was a long document giving very complete details of the tragedy. The essential portions of it read: “4th January. “At 7.21 to-day a telephone message was received from the Harwich boat wharf office at the Hook that a passenger had disappeared during the crossing under circumstances which pointed to suicide. Inspector Van Bien was sent down to make inquiries, and he obtained the following information: “Some little time before the boat berthed, the stewards, according to custom, went round the staterooms to arouse the passengers. There was no reply from stateroom N, a single-berth cabin on the port side, and when John Wilson, the steward in question, had knocked a second time, he looked in. The cabin was empty, but bore evidence of having been occupied. The bed had been lain on, though not slept in, a large suitcase was on the floor, and various articles of a man’s toilet were scattered about. The steward, thinking the traveller, whom he remembered to be a white-haired old man, was perhaps on deck, passed on. About half an hour later he looked in again, to find things in the same condition. He was engaged until after the boat berthed, but when the passengers were going ashore he went back to the stateroom, and again found everything as before. Becoming anxious, he reported the matter to the chief steward. The latter accompanied Wilson to cabin N, and they made a search. They found a half-sheet of paper and an envelope propped behind the tumbler in the little wooden shelf above the washstand basin. The former bore the words: “‘Financial embarrassments having made my life impossible, I am going to make an end of it to-night. I shall simply drop off the ship, and my death will be quick and easy. Please oblige by posting my letter.
