He was raising his gla.s.s to his lips when I put the question. He spoke before he drank. "A double? What on earth do you mean?"

"Because it was from the lips of your double I heard the name of Louise O'Donnel."

"My double?" He put down his gla.s.s, untasted.

"I came up with him in the same train last night from Brighton."

"You came up with him in the same train last night from Brighton? With whom?"

"Your double."

His face was absolutely ghastly. He had gone white to the lips, and a curiously unnatural, sickly white. I could not make him out at all. I suspected that he could not make me out either. I know that something about him had for me, just then, a dreadful sort of fascination.

"I do not know, Mr. Tennant, if you are enjoying a little jest at my expense. I am not conscious of having a double, nor am I conscious of having come up with you last night in the same train from Brighton. By what train did you travel?"

"By the 8.40 express."

"By the train, that is, which leaves Brighton at 8.40?"

"Yes; and which arrives in town at ten."

Unless I was mistaken, a look of distinct relief pa.s.sed over his face.

"Oh, then, you certainly never came from Brighton with me. It occurs to me, Mr. Tennant, that you are not looking well. You almost look as if you had had a recent serious shock. I trust that it is only my fancy."

He looked at me with eager, searching eyes, which reminded me very acutely of the stranger's.

"I am not feeling very well to-day, and that's a fact."

"You don't look very well. By the by, how came this double of mine to mention the name?"

Mr. Townsend nodded towards the sheet of paper, almost, as it seemed to me, as if he were unwilling to p.r.o.nounce the name which was upon it.

"He merely mentioned that he had been down to Brighton to look for a woman named Louise O'Donnel."

Mr. Townsend's gla.s.s came down on to the table with the same startled gesture as before. If he was not careful, he would break a second one.

And, since he glanced our way, so the waiter seemed to think.

"Been looking for her? What had he been doing that for?"

"That is more than I can tell you."

Mr. Townsend sat and stared at me as if doubting whether I spoke the truth.

"May I ask you, in my turn, what you know about this mysterious Louise O'Donnel?"

He looked down, and then up at me. He smiled, his smile striking me as being more than a little forced.

"That is the funny part of it. I, too, know nothing of Louise O'Donnel--no more than you do."

"It seems odd that you should take so great an interest in a person of whom you know nothing."

"Does not the same remark apply to you?"

"Not at all. I heard the name mentioned last night, casually, for the first time. It seems to have lingered in my memory, and I appear to have scribbled it, in a fit of abstraction, and, certainly, quite unconsciously."

Taking out a cigar, Mr. Townsend commenced to light it with an appearance of indifference which was, perhaps, a trifle too p.r.o.nounced.

"Very odd, very odd indeed, that both you and I should seem to evince so much interest in a person whose name we have merely heard casually mentioned. It occurred to me that, when you found the name confronting you, you appeared--shall I say startled?--as if it or its owner was connected in your mind with disagreeable a.s.sociations. Perhaps, however, that was simply a consequence of the general ill-health from which you say you suffer. And, I must say myself, that you don't look well. I hope that, next time I see you, you will be better."

He carried it off with an air. But I did not believe him. I felt persuaded that he knew more of Louise O'Donnel than he chose to confess. What he knew was more than I could say. But I felt equally persuaded that he wished that he knew less. He went off without saying anything further about the little deal which he had said that he wanted me to do for him. It had, apparently, escaped his recollection. I, too, had forgotten it till after he had gone. I had never felt less inclined for business in my life.

Scarcely had I returned to the office than the door opened, and, wholly unannounced, the stranger of the night before came in. He might, almost, have been waiting and watching for my return.

CHAPTER IV.

BLACKMAIL.

Again I was struck by the man's resemblance to Mr. Townsend. It was obvious even in the way in which he advanced towards me across the room. It was almost as if Townsend had slipped on some costume of a masquerade, and reappeared in it to play tricks with me. The fellow, going to the centre of the room, crossed his arms, in theatrical fashion, across his chest, and stood and stared at me--glared at me would be the more correct expression. Not caring to meet his glances, and to return him glare for glare, as if we were two madmen trying to outstare each other, I fumbled with the papers on my table.

"You have called for that handkerchief of yours? I am obliged to you for the loan of it; but I had to leave home for town so early this morning that my wife was not able to get it ready in time for me to bring it with me. If you will give me your address I will see that it is sent to you through the post."

There was a considerable interval before he answered me--an interval during which he continued to glare, and I to fumble with my papers.

When he did speak, it was in one of those portentous and a.s.sumed ba.s.s voices, which one inevitably connects with the proverbial "Villain at the Vic."

"I have not called for my handkerchief."

"Then, may I ask to what I am indebted for the pleasure of your presence here. I have only just come in, and I have some rather pressing business which I must do."

"Your business has nothing to do with me."

"Probably not; but it has with me."

He came a step nearer, still keeping his arms crossed upon his chest.

This time he spoke in a sort of a hiss. It seemed obvious that at some period of his career he must have had something to do with the stage.

"Do you not know what has brought me here. Does your own conscience not tell you, man?"

I began to suspect that he had been drinking. I looked up at him. He was eyeing me with a scowl which, to say the least of it, was scarcely civil.

"How should I know what has brought you here, if it is not a desire to regain possession of your property? I take it that you hardly intend to suggest a further deposit."

I do not think that he altogether relished the allusion. His scowl became less theatrical, and a good deal more natural. He seemed, for a moment, to be at a loss as to what to say. Then a word came from between his lips which startled me.

"Murderer!"
