You are in my house.' Her tongue was loosed, with a cry of indignation.
'If you are not a madman, let me go!' 'I am not mad.' His eyes terrified her, and she backed away from him towards the locked door.

She almost shrieked for fear.
'If you have a spark of human feeling, let me out!' 'I am human,' he answered grimly, but he did not move to follow her.
'By whatever you hold sacred, let me go!' She was wrenching at the lock in despair with both hands, but sideways, while she kept her eyes on his.
'I hold you sacred--nothing else.' 'Sacred!' Her anger began to outbrave her terror now.

'Sacred, and you have trapped me by a vile trick!' 'Yes,' he answered, 'I admit that.' He had not moved again and there was a window near her.

She sprang to it and thrust the curtains aside, hoping to open the frame before he could stop her.

But though she moved the fastenings easily, she could do no more, with all her strength, and Giovanni still stood motionless, watching her.
'You cannot open that window,' he said quietly.
