This evidence to me appeared conclusive. I gave the chambermaid a parting chuck under the chin—no one being about—and dismissed her.
Then, it being a fine morning, I went out for a walk.
I went right over the hills by Sham Castle and across the Golf Links, being heartily sworn at—in the distance—by sundry retired officers for not getting out of the way. But I was trying to have a good think over Mr. Saumarez, his duplicate glass eyes, and the reason why he wanted the key of the old lady's safe.
I so tired myself out with walking and thinking, with no result, that when I got back and had lunched late all by myself in the big dining-room, I went into the smoking-room, which this time was quite empty, and fell asleep in front of the great fire.
My sleep was curiously broken and unrestful, and full of that undefined cold apprehension which sometimes attacks one without any apparent reason during an afternoon nap.
I awoke at last to hear the old Abbey clock striking five, and then I nearly jumped out of my seat, for I recollected my promise to the unknown old lady in Monmouth Street to visit her again that day at that very hour.
I hurried through the hall to the coat room, and, seizing my hat, rushed out and just caught a tram which was gliding past in the direction of the upper town where Monmouth Street stretched its length along the slope of the hill.
It was only three minutes past five when the gaily lighted tram deposited me at the end of my old lady's street, and I set off for Number 190, which was at the other extremity of the long, badly lighted thoroughfare, looking, with its interminable rows of oblong windows, like an odd corner of the eighteenth century which had been left behind in the march of time.
I found the house practically as I had left it; there was no fog that evening, and I had a better opportunity of observing its general appearance in the yellow flare of the old-fashioned gas lamp opposite.
The house on one side of it was to be let, with a large staring board announcing that fact fixed to the railings; the house on the other side was a dingy looking place with lace curtains shrouding the dining-room windows and a notice outside concerning "Apartments."
