"I confess I am a little curious on the point," Jack said drily. "You are taking a great risk when you mention his name and assume that I am no friend of his."

"You couldn't be with a face like yours," the stranger replied. "A dupe, perhaps, or a man he was making use of; but never one of his infamous gang. And yet you were in that room with him a long time to-night."

Jack hesitated a moment before he spoke again.

"Look here," he said. "You have been fairly candid with me, and in return I will be as candid with you. Anstruther is a great scoundrel, and it is to my interest and to the interests of those I love that the man should be exposed and rendered harmless for the future. Now, how did you know that we were in the same bedroom together?"

"That is easily explained," said the other. "My male nurse was suddenly called away this evening on important business. I have been feeling so much better the last day or two that I decided to do without a substitute. Mind you, I knew perfectly well that Anstruther was frequently in the habit of spending an occasional night here. And I had my own reasons for keeping out of his way. But something happened to my bell to-night, and I had to go to the top of the corridor and use the bell there. It was quite by accident that I saw you enter Bedroom No. 14, and it was quite by accident, also, that I heard Anstruther demand to know why he could not have the same room. I listened with curiosity, because the thing struck me as very strange. It struck me as stranger still when I heard Anstruther say that the room was empty, and saw him close the door behind him."

"A kind of vanishing trick," Jack smiled. "Well, yes, if you like to put it in that way," the other said. "It was either one of two things--you were there as an accomplice, which I refuse for one moment to believe, or you had hidden yourself in the room for the purpose of watching Anstruther. In fact, seeing that circumstances were going for you, you laid a neat little trap for Anstruther. Have I not guessed it correctly?"

"Your deductions are perfectly sound," Jack said. "I deliberately chose that bedroom with the full intention of overhearing what was going on in the room behind. When I heard Anstruther come in, I hid myself in the wardrobe and stayed there till he left the room. Now I have told you all that has happened so far as I am concerned. It is your turn to be communicative."

"I am exceedingly sorry to appear discourteous," the stranger said; "but I am afraid I cannot tell you very much. The mere mention of Anstruther's name always throws me into a kind of terror. I may be able to help you later on, but for the present I am bound to silence. But tell me now, do you see any likeness between Anstruther and myself?"

The question was asked with an eagerness that struck Jack as being far beyond the necessity of so simple a query. The speaker seemed to fairly tremble for Jack's reply.

"There does not begin to be any resemblance," he said. "The question strikes me as being a strange one. And now let me ask you a question. From what you say, you appear to know Anstruther exceedingly well. Now, did you ever notice his likeness to anybody? You have seen him when he has been greatly moved to passion, I suppose?"
