"Well, if nothing happens shortly—and I'm inclined to think nothing will——" began Major Carstairs, but he got no further, for with the extraordinary aptness of conjunction which we are wont to call coincidence, though another word might more fitly be employed, the door opened almost noiselessly and a hooded figure crept on soundless feet into the room.

Anstice and his companion fairly held their breath as the shrouded form glided softly forward, the light of the dying fire doing little, now, to illumine the scene; and neither of the men could have sworn with any certainty to the identity of the person who shared their occupation of the silent room.

In the middle of the floor the figure halted suddenly; and for one wild moment Anstice fancied that some sixth sense had warned the new-comer of their presence; but realizing the danger of attracting that new-comer's thought towards him by any intensity of his own mind—for one thought will draw another as a magnet the steel—Anstice switched off the current of his thoughts, so to speak, and waited with as blank a mind as he could compass for the thing which must surely happen soon.

After that involuntary halt the figure moved slowly forward in the direction of the writing-table; and Anstice would have given a great deal to have been able to see the face of this midnight scribe; but as yet the firelit gloom remained undisturbed; and it was impossible to do more than hazard a guess as to this strange visitor's personality.

There were candles on the writing-table, and for a moment Anstice fancied that the mysterious figure would seek their aid to carry through the task confronting her—he was convinced it was a woman who sat at the table—but he was wrong, for no match was struck, no candle-flame lighted the soft dusk. Instead a small beam of light shot suddenly across the table; and Anstice and Major Carstairs both grasped at the same moment the significance of the ray.

It was a pocket electric torch, of a kind familiar to thousands nowadays, whose aid the letter-writer had evoked; and since this particular one was fitted with a bulb which enabled it to cast a continuous light without finger-pressure, it was quite effective for the purpose to which it was now being put.

Having placed the torch on the table in such a position that the ray of light fell directly across the blotting-pad, the figure made search for a sheet of paper which suited its mind; and after a moment, a sheet having been chosen, a pen was selected, dipped into Chloe's own silver inkstand and a few lines of writing inscribed slowly, and with many pauses, upon the otherwise unsullied paper.

His heart throbbing wildly, with an excitement quite foreign to his nature, Anstice watched the performance eagerly through the just-parted curtains; and so sure was he now of the identity of his quarry that he was ready to leap from his hiding-place and confront the anonymous letter-writer without further loss of time, had not a gentle pressure on his arm restrained him at the critical moment.

It was not safe to speak, since even a whisper might betray their presence; but Anstice realized Major Carstairs' intention and held himself in check, though he quivered like a greyhound straining at the leash, who fears his quarry may escape him if he be not slipped forthwith.

After what seemed like an hour, but was probably five minutes, the letter, whatever its nature, was judged complete; and with the same stealthy but unhurried movements the writer sought and obtained an envelope from the many which lay ready to hand and slipped the missive in with deft fingers. An address added, the abominable thing was complete; and having quietly put everything in order, so that even the most acute eyes could discover nothing amiss, the writer rose softly from the chair, and taking up the electric torch extinguished its beam preparatory to making her exit from the room, which was now in almost complete darkness.
