"I do, Gertrude," I said; "and after that I want my breakfast. I have a lot to do today."

The head withdrew itself, tittering; and a moment later I heard a shrill voice calling down the kitchen stairs.

"Grahnd floor wants 'is 'ot water quick."

Within about five minutes the ground floor's wish was gratified, Mrs. Oldbury herself arriving with a large steaming can which she placed inside a hip bath. She asked me in a mournful voice whether I thought I could eat some eggs and bacon, and having received a favourable reply left me to my toilet.

It was about a quarter to eight when I sat down to breakfast. Considering that for three years I had been obliged to rise at painfully unseasonable hours, this may appear to have been unnecessarily energetic, but as a matter of fact I was not acting without good reasons.

To start with, it was my purpose to spend a pleasant morning with George. I wanted to be outside his house so that I could see his face when he came out. I felt sure that as long as I was at liberty he would be looking worried and depressed, and I had no wish to postpone my enjoyment of such a congenial spectacle.

Then, provided that I could restrain myself from breaking his head, I intended to follow him to Victoria Street or wherever else he happened to go. Beyond this I had no plan at the moment, but at the back of my mind there was a curious irrational feeling that sooner or later I should stumble across some explanation of the mystery of Marks' death.

I knew that as a rule George didn't start for business until nine-thirty or ten. I was anxious to get out of the house as soon as possible, however, just in case I was correct in my idea that the gentleman with the scar was keeping a kindly eye on my movements. In that case I thought that by departing before half-past eight I should be almost certain to forestall him. If, as I believed, he was under the impression that I had been indulging in a night's dissipation, it was unlikely that he would credit me with sufficient energy to get up before ten or eleven. As to waiting for George—well, I had no objection to that. It was a nice sunny morning, and I could buy a paper and sit on one of the embankment seats.

This, indeed, was exactly what I did. I slipped out of the house as unobtrusively as possible, and, stopping at a little newspaper and tobacco shop round the first corner, invested in a Telegraph and a Sportsman. Then, after making sure that I was not being followed, I set off for the embankment.

Some of the seats were already occupied by gentlemen and ladies who had apparently been using them in preference to an hotel, but as luck would have it the one opposite George's house was empty. I seated myself in the corner, and after cutting and lighting a cigar with the care that such an excellent brand deserved, I prepared to beguile my wait by reading the D.T.
