"Come, then, and we will look for them," said Berwin in a tremulous voice.

"But they have gone by this time!"

"Gone!"

"Yes," said Denzil rapidly. "I rang the bell, as I fancied there was some fatal quarrel going on within. At once the light was put out, and as I could attract no one to the door, I suppose the man and woman must have fled."

For a moment or so Berwin said nothing, but his grip on Lucian's arm relaxed, and he moved forward a few steps. "You must be mistaken, Mr. Denzil," said he in altered tones, "there can be no person in my house. I locked the door before I went out, and I have been absent at least two hours."

"Then I must be mad, or dreaming!" retorted Lucian, with heat.

"We can soon prove if you are either of the two, sir. Come with me and examine the house for yourself."

"Pardon me," said Denzil, drawing back, "it is none of my business. But I warn you, Mr. Berwin, that others are more curious than I am. Several times people have been known to be in your house while you were absent, and your mode of life, secretive and strange, does not commend itself to the householders in this neighbourhood. If you persist in giving rise to gossip and scandal, some busybody may bring the police on the scene."

"The police!" echoed the old man, now greatly alarmed, as would appear from his shaking voice. "No! no! That will never do! My house is my castle! The police dare not break into it! I am a peaceful and very unfortunate gentleman, who wishes to live quietly. All this talk of people being in my house is nonsense!"
