'I was down at the village,' she said. 'I followed Mr. Steinletter here. I had a special permit, a military pass. I was supposed to be related to one of the officers quartered at the inn. I made a few inquiries about this place, which increased my suspicions. Then I met Mrs. Silburn outside the lodge gates. She was with the Colonel in command here and they stopped to speak to the officer I was with. She was delightful and asked me to call. I was only too glad to have a chance of obtaining the entrée to the house. They made me send for my clothes, to spend the night. That was two days ago. Since then I have tried in vain to get away.' 'Let me understand what you mean by trying to get away?' he begged. 'Surely you could ask for a car to take you to the station?' 'I have done so three times,' she replied, 'always with the same result. They assure me that every car in the garage has been requisitioned by the Government. I go to that dummy telephone--the exchange is in the house, you know--and of course nothing happens. If I start out to walk, I am shadowed by one of the men-servants, and, as you know, it is two miles before one reaches the road.' 'Well, there isn't much they can do with us, dear,' Lavendale assured her coolly. 'Tell me now, have you made any actual discovery?' 'There is a private telegraph and telephone exchange here in the place,' she said, 'and Mr. Silburn gets messages every few hours. There are people always coming and going, all people of the same class. There is not the slightest doubt that this is the place for which we have searched. Ambrose, if only we could stretch out the net now, at this moment, we could make a great haul.' 'Instead of which,' he remarked grimly, 'we seem to be in the meshes ourselves!' 'Tell me,' she begged, 'does any one know that you were coming here?' 'I told Elwell--Major Elwell,' Lavendale replied, with a suddenly inspired flash of memory. 'I told him why I was coming here, too.' She clutched at his arm. Then suddenly she looked down. 'They are watching us,' she whispered. 'Ambrose, that may save us yet if only he comes in time!' 'In time for what?' Lavendale answered cheerfully. 'I can't look upon this as very serious, dear. Why, Lydia Silburn is my own cousin.' 'She is our only hope,' Suzanne declared. 'As for the rest, I have grown to suspect every one of them.' 'What does this half-past ten business mean?' he asked. She shook her head. 'At half-past ten they all go into what they call the cloister room,' she said. 'As yet I have not been invited there, but I have an idea that to-night we are both to be present. Yes, here comes Mr. Silburn.' 'Now, you young people,' their host observed pleasantly, 'we are going to let you into a few secrets. This way.'
