That little woman, all on fire with curiosity, made various inquiries of her gossips regarding the doings of Mr. Berwin, and in default of reporting the same to her lodger, occupied herself in discussing them with her neighbours. The consequence of this incessant gossip was that the eyes of the whole square fixed themselves on No. 13 in expectation of some catastrophe, although no one knew exactly what was going to happen.

This undefinable feeling of impending disaster communicating itself to Lucian, stimulated his curiosity to such a pitch that, with some feeling of shame for his weakness, he walked round the square on two several evenings in the hope of meeting Berwin. But on both occasions he was unsuccessful.

On the third evening he was more fortunate, for having worked at his law books until late at night, he went out for a brisk walk before retiring to rest. The night was cold, and there had been a slight fall of snow, so Lucian wrapped himself up well, lighted his pipe, and proceeded to take the air by tramping twice or thrice round the square.

Overhead the sky was clear and frosty, with chill glittering stars and a wintry moon. A thin covering of snow lay on the pavement, and there was a white rime on the bare branches of the central trees.

On coming to the house of Berwin, the barrister saw that the sitting-room was lighted up and the curtains undrawn, so that the window presented a square of illuminated blind. Even as he looked, two shadows darkened the white surface--the shadows of a man and a woman. Evidently they had come between the lamp and the window, and so, quite unknowingly, revealed their actions to the watcher. Curious to see the end of this shadow pantomime, Lucian stood still and looked intently at the window.

The two figures seemed to be arguing, for their heads nodded violently and their arms waved constantly. They retreated out of the sphere of light, and again came into it, still continuing their furious gestures.

Unexpectedly the male shadow seized the female by the throat and swung her like a feather to and fro. The struggling figures reeled out of the radiance and Lucian heard a faint cry.

Thinking that something was wrong, he rushed up the steps and rang the bell violently. Almost before the sound died away the light in the room was extinguished, and he could see nothing more. Again and again he rang, but without attracting attention; so Lucian finally left the house and went in search of Blinders, the policeman, to narrate his experience. At the entrance of Geneva Square he ran against a man whom he recognised in the clear moonlight.

To his surprise he beheld Mark Berwin.

CHAPTER III

AN UNSATISFACTORY EXPLANATION

"Mr. Berwin!" cried Lucian, recognising the man. "Is it you?"

"Who else should it be?" replied Berwin, bending forward to see who had jostled him. "Who else should it be, Mr. Denzil?"

"But I thought--I thought," said the barrister, unable to conceal his surprise, "that is, I fancied you were indoors."

"Your fancy was wrong, you see. I am not indoors."

"Then who is in your house?"

Berwin shrugged his shoulders. "No one, so far as I know."

"You are mistaken, sir. There was a light in your room, and I saw the shadows of a man and a woman struggling together thrown on the blind."

"People in my house!" said Berwin, laying a shaking hand on the arm of Lucian. "Impossible!"

"I tell you it is so!"

"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!"

"Yet you seemed afraid when I told you of the shadows," said Lucian pointedly.

"Afraid! I am afraid of nothing!"

"Not even of those who are after you?" hinted Denzil, recalling the conversation of the previous occasion.

Berwin gave a kind of eldritch shriek and stepped back a pace, as though to place himself on his guard. "What--what do you know about such--such things?" he panted.

"Only so much as you hinted at when I last saw you."

"Yes, yes! I was not myself on that night. The wine was in and the wit was out."

"The truth also, it would seem," said Lucian drily, "judging by your agitation then and now."

"I am an unfortunate gentleman," whimpered Berwin tremulously.

"If you will excuse me, sir, I shall leave you," said Lucian ceremoniously. "It seems to be my fate to hold midnight conversations with you in the cold, but I think this one had better be cut short."

"One moment," Mr. Berwin exclaimed. "You have been good enough to place me on my guard as to the talk my quiet course of life is causing. Pray add to your kindness by coming with me to my house and exploring it from attic to bas.e.m.e.nt. You will then see that there are no grounds for scandal, and that the shadows you fancy you saw on the blind are not those of real people."

"They can't be those of ghosts, at all events," replied Lucian, "as I never heard, to my knowledge, that spirits could cast shadows."

"Well, come and see for yourself that the house is empty."

Warmly as this invitation was given, Lucian had some scruples about accepting it. To explore an almost unfurnished mansion with a complete stranger--and one with an ill reputation--at the midnight hour, is not an enterprise to be coveted by any man, however bold he may be. Still, Lucian had ample courage, and more curiosity, for the adventure, as the chance of it stirred up that desire for romance which belongs peculiarly to youth. Also he was anxious to satisfy himself concerning the blind shadows, and curious to learn why Berwin inhabited so dismal and mysterious a mansion. Add to these reasons a keen pleasure in profiting by the occurrence of the unexpected, and you will guess that Denzil ended by accepting the strange invitation of Berwin.

Being now fully committed to the adventure, he went forward with cool courage and an observant eye, to spy out, if possible, the secret upon which hinged these mysteries.

As on the former occasion, Berwin inducted his guest into the sitting-room, and here, as previously, a dainty supper was spread.

Berwin turned up the lamp light and waved his hand round the luxuriously furnished room, pointing particularly to the s.p.a.ce between table and window.

"The figures whose shadows you saw," said he, "must have struggled together in this s.p.a.ce, so as to be between the lamp and the blind for the performance of their pantomime. But I would have you observe, Mr.

Denzil, that there is no disturbance of the furniture to show that such a struggle as you describe took place; also that the curtains are drawn across the window, and no light could have been thrown on the blind."

"The curtains were, no doubt, drawn after I rang the bell," said Lucian, glancing towards the heavy folds of crimson velvet which veiled the window.

"The curtains," retorted Berwin, stripping off his coat, "were drawn by me before I went out."
