The driver was stupid and suspicious, but in time the details came out. The most direct route led along Holborn, and he had taken it, but when he reached the point in question the young man had hailed him through the speaking tube. “Hold on a minute, driver,” he had called. “Look sharp, please.” He had pulled over to the kerb, but almost before he had come to a stand the young man had jumped out and had hurried across the street. The lady had then alighted, had told Tomkins to wait, and had followed him. Tomkins had at first feared he was going to lose his money, but after a couple of minutes they had both returned and the girl had got in. She had bidden good-night to her friend, and he, Tomkins, had driven her off, leaving the man standing on the pavement. On arrival at Hampstead, the lady had paid him and entered the house. As far as the driver had noticed neither of the young people was excited or upset. This information gave French cause for thought. On obtaining Harrington’s statement on the morning after the murder, he had imagined the young man was keeping something back. And now he found that he had been right. The young fellow had not mentioned the fact that he had been within a few yards of the scene of the crime at the time at which it had taken place. He had stated that he had seen Sylvia home, and now it appeared he had not done so, but had accompanied her only half-way. French reminded himself with satisfaction that his instinct on such a point was seldom far astray. Furthermore, this news confirmed his growing suspicion that Miss Duke also knew something about the affair. It seemed too far-fetched a coincidence that this unexpected stop near the scene of the crime, the mental upset of both herself and Harrington, and the postponing of the wedding, were unconnected with the tragedy. What the connection might be he could not imagine but he could not but believe it existed. Determined to put the matter to the test without further delay, he drove to the Hatton Garden office and asked for Harrington. The young fellow received him politely, though French thought he could sense an air of strain in his manner. After the briefest greeting he came directly to the point. “Mr. Harrington,” he began, “I want to ask you one question. In our conversation on the morning after the crime you told me you had seen Miss Duke home on the previous night. Why did you state this when you had only seen her as far as Hatton Garden?” The young man paled somewhat. He did not seem taken aback, rather he gave French the impression of feeling that he was now face to face with a crisis he had long expected. He answered without hesitation and with an evident attempt at dignity. “I quite admit that I left Miss Duke near the end of Hatton Garden, but I don’t admit that that was in any way inconsistent with what I told you. Certainly I had no intention of deceiving you.”
