"I knew it was you," he said, pulling Leo into the room and shutting the window. "It is a lucky thing you remembered my signal, else I might have drilled a hole in you. You come at a happy moment." Here he stopped and looked suspiciously at the young man. "Have you that infernal Marton with you?" he asked, with a glance at the window and a movement towards the revolver. "No, no," replied Leo, hastily. "I am all alone." "That's a good thing," said Pratt, grimly. "I won't be taken alive, I promise you. But I knew you would not give me away. I said so to Mrs Gabriel. She said you would--speaking the worst of you as usual." Leo was too much taken aback by the discovery that Pratt was in the castle to reply immediately. Moreover, the man was so cool and composed that he felt as though he were in the wrong. He tried to collect his scattered thoughts, but before he could open his mouth Mrs Gabriel spoke in her usual domineering tones. "What are you doing here, Leo?" she asked. "How did you get on to the terrace? No one can get on without the key of the gate." "I happen to have the key," said Leo, showing it. "You gave it to me yourself some years ago. When I left you I took it with me by mistake. It has come in useful to-night. You may thank your stars, both of you, that I did not bring Marton back with me. He left me at the foot of the hill with a story that you were ill, Mrs Gabriel." "Leo," said Pratt in an agitated tone, "surely you would not have brought the man here to get me into trouble?" "I did not know you were here," said Haverleigh, carelessly, for he was still angered at the man. "I have been here ever since the night I fled from Raston's house. It was Adam who went on to London and cut the wire." "And the letter in which you said you had stolen the cup?" "I wrote that here and posted it to Adam that he might send it from London. Mrs Gabriel helped me to hide. No one knows that I am in this house save herself, and now you are a sharer in our secret." "It must be difficult to keep your presence here a secret from the servants," said Leo, wondering how the man had forced Mrs Gabriel to help. Here the lady herself interfered. "It is not difficult at all," she said in her most offensive tones. "You know nothing of what you are talking about. Pratt is up in the tower room, and I take him food myself from my own meals. It is impossible that anyone can guess." "Well, my dear aunt," said Haverleigh, emphatically, "I know that Pratt is here. I think, therefore, you had better behave towards me in a more civil manner." "Ha!" scoffed Mrs Gabriel, folding her arms and looking defiant. "You would not dare to state the truth." "How do you know that?" said Leo, dryly. "Pratt is wanted by the law. He committed a theft here and allowed me to lie under suspicion. Why should I not give him up and accuse you of being an accessory to his concealment?"
