Her face had become thin and haggard, with dark rings around her eyes and upon it was a wild, hunted expression, which she strove to disguise, but in vain.

She now treated me with a strange, cold indifference, so unlike her real self, while her attitude was one of constant attention and strained alertness.

The woman Petre had apparently not been approached by Scotland Yard, therefore as the days went by I became more and more anxious to see her, to speak with her—and, if necessary, to come to terms with her.

Therefore, without a word to anyone, I one evening caught the six o'clock train from Liverpool Street, and before eight was eating my dinner in the big upstairs room of The Cups Hotel, while the hall-porter was endeavouring to discover for me the whereabouts of Melbourne House.

I had nearly finished my meal when the uniformed servant entered, cap in hand, saying:

"I've found, sir, that the house you've been inquiring for is out on the road to Marks Tey, about a mile. An old lady named Miss Morgan lived there for many years, but she died last autumn, and the place has, they say, been let furnished to a lady—a Mrs. Petre. Is that the lady you are trying to find?"

"It certainly is," I replied, much gratified at the man's success. Then, placing a tip in his palm, I drank off my coffee, put on my overcoat, and descended to the taxi which he had summoned for me.

He gave directions to the driver, and soon we were whirling along the broad streets of Colchester, and out of the town on the dark, open road which led towards London. Presently we pulled up, and getting out, I found myself before a long, low, ivy-covered house standing back behind a high hedge of clipped box, which divided the small, bare front garden from the road. Lonely and completely isolated, it stood on the top of a hill with high, leafless trees behind, and on the left a thick copse. In front were wide, bare, open fields.

Opening the iron gate I walked up the gravelled path to the door and rang. In a window on the right a light showed, and as I listened I heard the tramp of a man's foot upon the oilcloth of the hall, and next moment the door was unlocked and opened.

A tall, thin-faced young man of somewhat sallow complexion confronted me. He had keen, deep-set eyes, broad forehead, and pointed chin.
