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.'

They both rose. The others were crossing the hall towards the eastern corridor. Mr. Silburn drew Suzanne's arm through his. As they walked his face became more serious. Lavendale had a wild idea, for a moment, of snatching Suzanne away, opening the front door by force and clamouring for freedom. Then he remembered the two miles to the lodge gate and shrugged his shoulders.

'It's rather a queer apartment into which I am going to take you,' Mr. Silburn explained, 'a crazy sort of place, really, but to us Americans this sort of room, I must confess, appeals some. Allow me, Miss de Freyne.'

He motioned them both to precede him. They found themselves in what seemed to be, from the bareness of the walls and the shape of the windows, a small chapel, built on different levels. The larger part of the room, which was below, was wrapped in complete gloom. The smaller part was unfurnished save for a long table, around which was ranged a number of chairs. One by one, the guests seated themselves. Lavendale and Suzanne followed their example as indifferently as possible. Mr. Silburn sat at the head of the table, with Lady Marsham on his right and Mr. Steinletter opposite. There was a certain significance to Lavendale in the fact that his cousin was not present. A somewhat gloomy light was thrown upon the faces of the little company from a heavily-shaded oil lamp suspended by a brass chain from the roof, and, looking around at their mingled expressions, Lavendale for the first time felt a sense of real danger, a thrill of something like fear, not for his own sake but for Suzanne's. He groped for her hand beneath the table and held the icy-cold fingers tightly.
