"Poor child! how you tremble! Draw your cape more forward; the bitter cold requires it. Are you trembling from fear?"

"No; only from cold." But I tried in vain to think so.

"A steady hand and steadfast nerve are wanted for your task. If you cannot rely on them, say so at once. In five minutes you will have no retreat."

"I shall be better directly. But I am so cold. Inspector Cutting, it must be freezing hard-ten degrees, I should think."

"It does not freeze at all. I see we must warm you a little. But no more 'Inspector Cutting,' if you please, until to-morrow."

Hereupon he led me into a little room, fenced off from the bar of some refreshment-house. A glorious fire was burning, by which he set and left me. Presently he returned, with a small glass in his hand.

"Drink this, young lady. It will warm you, and brace your nerves."

I saw by the firelight that it was brandy, or some dark-coloured spirit.

"No, I thank you. Do you suppose that I require Dutch courage?"

I threw such emphasis on the personal pronoun, and looked at him so indignantly, that he laughed outright.

"I thank you in turn. You suppose that I do. I will justify your discernment." And with that he tipped it off, and then returned to business, all the graver for the interlude.

"Now, if you are really warm, we will start again. Stop one moment. I have heard you cough two or three times. Can you keep it under?"

I assured him that I could very easily do so, and that it was nothing but the sudden effect of the cold. Forth we went again into the winter night, after I had learned from him that we were now in Whitechapel, not far from Goodman's Fields.

After another short walk, we came to the end of a narrow by-street, where there was an archway. Passing through this archway, we descended some steep and broken steps. Then the Inspector produced a small lamp brightly burning, which he must have lit at the public-house. It was not what is called a bull's-eye, but a reflector-lamp. By its light I saw that the chief entrance to the house must be round the corner, and perhaps in another street. With a small key which he took from his pocket, Mr. Cutting unlocked a little iron gate, and we entered a narrow passage. At the end of it was a massive door studded with great nails. Here my guide gave a gentle knock, and hid the lamp as before.

Presently we heard a shrill sound from the keyhole, like a dryad's voice. The Inspector stooped thereto, and pronounced the password. Not without some difficulty the lock was turned and the bolts withdrawn, and we stood inside. A child, under-sized and unnaturally sharp, stared at us for a moment, then dodged away from the lamp, as if more accustomed to darkness. Mr. Cutting closed the door and refastened it, then led me through some basement rooms unpaved and unfurnished, until we came to an iron step-ladder. This he ascended, and helped me up, and we found ourselves in a small dark lobby, containing no furniture, except a high three-legged stool. When he closed his lamp all around was dark, but on the rafters overhead a faint patch of light appeared-ceiling there was none.

"Do you see that light?" he whispered to me, pointing, as I could just perceive, to a narrow glazed opening high in the wall, whence the faint gleam proceeded.

"Then jump upon this stool, and do your best to see through."

He cast the light of his lamp upon the stool for a moment, while I did as he bade me. Standing there, I found that I was tall enough to look through; but the narrow pane which formed the window was thickly covered with size, or some opaque integument. All I could tell was, that the space beyond was lighted.

"I know you can't see now," he said, as I came down despairing, "but you shall see by and by. The fools who were here before sized the glass on the wrong side, and this lot, though much sharper, have not corrected the error. They keep that window for escape in the last resort. Now take this bottle and this camel's-hair brush; it will make the glass transparent without the smallest noise. The men are not there yet. We could easily rub it clear now, but they will examine it. When the time comes, use the liquid most carefully and lightly, and don't spread it higher than an inch from the bottom of the frame. The lights are at this end; the shadow of the sill will allow you just an inch."

"And how far may I go horizontally?"

"The whole length of the glass, to command as much view as possible. The effect will pass in three or four minutes, but you must not do it again. If you do, the glass will fly, and you will be in their hands. Desperate men they are, and though I shall be near, I might be too late to save you. See all you can, to be able to swear to them all."

"How shall I know the one?"

"I cannot tell you. I must leave it to your instinct, or your intuition. I only know myself that he is one of the four. My information, such as it is, was obtained very oddly, and I trust to this night's work to make it more precise. One thing more: No noise, if you value your life. Keep the bottle stopped. Don't let the stuff drop on you; don't put your eyes to it, or it will blind you for ever. There is very little of it, because it is so deadly."

"When shall I do it?"

"In one hour from this time. Take this repeater. I have shown you how to use it. Look well at it now, while you have the light."

I looked at the watch; it was nearly midnight.

"Am I to be left in the dark-all in the dark here, by myself?"

"Yes. I must be seen elsewhere, or the whole thing fails. They know me even in this dress, and they watch me as I do them. But for to-night I believe I have misled them. When it is over, wait here till I come for you, or the little girl you saw."

"Oh! I wish I had never come; and all so vague and indecisive!"

"You can go back now, if you please; though ever that would be dangerous."

"I will not go back. No doubt I shall know him. When will you secure him?"

"When my evidence is completed. Now, remember, you have to deal with men keen as hawks, and stealthy as tigers. But there is no real danger, if you keep your self-command. Observe all four as narrowly as you can, both for your own sake and for mine. Be careful to stand on the centre of the stool. But you had better not get upon it until they have searched the room. Now, good-bye. I trust to your courage. If any harm comes, I will avenge you."

"A comfort that! What good will it be to me?"

"If vengeance is no good, what are you doing here?"

"Thank you. That is no business of yours. Don't let me detain you."

He told me afterwards that he had vexed me on purpose to arouse my mettle. And I am sure I needed it.

"Ah! now you are all right. If your caution fails you, the man who slew your father will be sure to escape us."

"If it fails me, 'twill be from anger, not from terror."

"I know it. Let me look at you."

He threw the full light on my face. The burnished concave was not brighter or firmer than my eyes.

"Pale as death, and quite as resolute. Rely only upon yourself."

"God and myself," I whispered, as he glided out of sight along the vaults below. I could see no other entrance to the place in which I sat; but how could I tell?

For a minute excitement kept me hot; but as the last gleam of the light died upon the wall below, my heart began to throb heavily, and a chill came over me. The pulse thumped in my ears, like a knocking in the cellar. "Was it fear?" I asked myself, in scorn that I should ask. No, it was not fear, but horrible suspense. The balance of life and death, of triumph and disgrace, swung there before me in the dark, as if my breath would turn it. No dream of a child, no vagary of the brain-the clear perception of strong will and soul poised upon this moment.

The moment was too long; the powers began to fail, the senses grew more faint and confused at every heavy throb. Little images and little questions took the place of large ones. In vain I looked for even a cobweb, or the skeleton of a fly, where the dull light flickered through the pane of glass. In vain I listened for a mouse. Even a rat (much as I hate him) would have been welcome then. The repeater was purposely made so low of tick, that I got no comfort thence. All was deep, unfathomable silence, except the sound of my rebel heart.

As a forlorn hope, I began to reckon sixty slowly, as a child keeps with a ticking clock.

It would not do. My heart was beating louder than ever, and my hands were trembling; even my teeth rattled like dice in a box as the time approached.

The nerves will not be hoodwinked; the mind cannot swindle the body. I once slapped the cheeks of my governess. I cannot treat nature so. Try the sweet influence, and the honest coin of reason. It will not do. All trembling, I strike the repeater. Five minutes more, and the trial must come. My heart is fluttering like a pigeon's throat. The long suspense has been too much. Oh! why was I submitted to this cruel ordeal? The walls are thick. I can hear no movement in the secret room.

There comes a creeping, fingering, sound, as of one whose candle is out, groping for the door. It passes along the pane of glass, and a shadow is thrown on the rafter. Who can it be? What stealthy hand but that of my father's murderer?

The word-the thought is enough. What resolution, reason, justice, all in turn, have failed to do, passion has done at once-passion at myself, as well as at my enemy. Is it Clara Vaughan, who, for eight long years of demon's reign, has breathed but for this moment-is Clara Vaughan to shake like the wooden-legged blackbird now her chance is come?

A rush of triumph burned, like vitriol, through my veins. Every nerve was braced, every sense alert and eager. Against the light of that window, dull as it was, I could have threaded the finest needle that ever was made.

I struck my repeater again. It was the hour, the minute, when my father died. With the mere spring of my instep I leaped upon the stool. I could see it clearly now. I dipped the broad camel's-hair brush in the flat phial, holding it carefully at arm's length, and then drew it lightly along the pane, quite at the bottom, from
