'We went into the dining-room, and dinner was served,' she recommenced, 'and there I had my first shock, my first doubt, for one of the two waiters was your spy.'

'Shawn! My detective!'

Hugo was surprised to find that Albert, almost a novice in his vocation, had contrived to be so insinuating.

'And he made a very bad waiter indeed,' Camilla added.

'I regret it,' said Hugo. 'He meant well.' 'When the waiters had gone I asked Mr. Tudor if they were his own servants. He hesitated, and then admitted frankly that they were not. He told me that his servants were out on leave for the evening. "You don't mean to say that I am now alone with you in the flat!" I protested. "No," he said quickly. "Mrs. Dant is always in her room across the passage. Don't be alarmed, dearest." His tone reassured me. After coffee, he took my photograph by flashlight. He printed one copy at once, and then, after we had both been in the dark-room together, he returned there to get some more printing-paper. While he was absent I went into the housekeeper's room for a handkerchief which I had left there. Mrs. Dant was not in the room. But in a mirror I saw the reflection of a man hiding behind the door. I was awfully frightened. However, I pretended to see nothing, and tried to hum a song. I same into the passage. The passage window was open, and I looked out. Another man was watching on the balcony. Of course, I saw instantly it was a plot. I—I—'

'Did you recognise the men, then?' Hugo asked.

'The one in the room I was not quite sure of. The other, on the balcony, was your detective, I think. I saw him disappear in this direction.'

'But whatever the plot was, Shawn had no hand in it.'

'No, no, of course not! I see now. But the other, in the room! Ah, if you knew all my history, you would understand better! I felt that some vengeance was out against me. I saw everything clearly. I tried to keep my head, and to decide calmly what I ought to do. It was from a little table in the passage that I picked up the revolver. Then I heard hurried footsteps coming through the drawing-room towards the passage. It was Mr. Tudor. He seemed very startled. I tried to appear unconcerned. "What is the matter?" he asked; he had gone quite pale. "Nothing," I said. "I only went to fetch a handkerchief." He laughed uneasily. "I was afraid you had thought better of it and run away from me," he said. And he kissed me; I was obliged to submit. All this time I was thinking hard what to do. I suggested we should go on to the roof garden for awhile. He objected, but finally he gave way, and he brought me the cloak and hat, and we went to the garden and sat down. I felt safer there. At last I ventured to tell him that I must go home. Of course, he objected to that too, but he gave way a second time. "I will just speak to Mrs. Dant," I said. "You stay here for three minutes. By that time I shall be ready." And I went off towards the flat, but as soon as I was out of his sight I turned and ran here. And that's all.'

'You are a wonderful creature,' Hugo murmured, looking at her meditatively.
