"I am vexed," he said, "about Edith. She went to town for a day's shopping on Wednesday and has not returned. She was to lunch with Mrs. Llewellyn and come back for dinner. She has frequently made these little excursions of late. In the evening, however, I got a telegram to say she was detained by the dressmaker, and yesterday morning a letter to the same effect. This morning I had no letter, but half an hour ago I met General Anson--he had just arrived by the three o'clock train. He told me that he had seen Edith having lunch at Franconi's with Fortescue. They did not see him--his table was behind theirs--but as he left the room he passed close to them and heard Fortescue say, 'To-night, then, without fail, by the seven-thirty.' 'So,' the old man went on, 'I suppose Lady Maxwell comes down to-night, and Mr. Fortescue is to escort her. I thought there was a coolness--that he was under a cloud.' I laughed, and told him it was a case of mistaken identity." "And Fortescue?" "He went to London yesterday; I happen to know that." I must here mention that Stony Lea, although but a small village in Kent, has a good train service, and is but an hour's run from town. I looked at my watch. It was barely four o'clock. "Why not," I said, "go up to town by the four-forty-five, and travel down yourself with Lady Maxwell when she is prepared to come? You could be in Belgrave Road before six o'clock." "Will you come with me?" he asked. I consented; and by 6.30 we were in Belgrave Road. Mrs. Llewellyn's house had an empty, uninhabited air, and the servant who came to the door said his mistress had been out of town for a few days. Lady Maxwell had been staying there during the week. She had driven out in the morning and not returned until four o'clock; then, after a cup of tea, she had gone out again, walking; she had said she was leaving town that evening, and would return about half-past six in a cab for various parcels that were awaiting her. "Quite so," Sir Lewin said; "she is travelling down with me. I will wait for her here," and he walked straight into the drawing-room, whither I followed him. The room opened into the hall. Presently a hansom drove up; Lady Maxwell got out and entered the house with a latch-key. Sir Lewin moved towards the door of the room as though intending to meet her, when the arrival of another cab made him pause and look round. Lady Maxwell ran lightly upstairs; the door was ajar and I heard the swish-swish of her skirts. The second cab was a four-wheeler; Fortescue descended from it, and the electric bell of the front door tingled persistently in the silence of the house. Then we heard him asking for Lady Maxwell, and almost before the servant could reply Sir Lewin was on the doorstep. Fearful of what might ensue I followed him from the room; I saw him touch Fortescue on the shoulder, and Allan's start of surprise and, apparently, dismay; then the two men entered the hall together.
