Next day I went to the office in Great George Street and reported upon the business I had done in York—and good business it was, too, with the Municipal Electric Supply—and in the evening I returned across Hammersmith Bridge at about six o’clock.

At seven our buxom “Kaiserin” put our meal upon the table—a roast, a sweet, and a wedge of Cheshire cheese. The mind of the dear old soul, who had so many relations, never rose above the butcher’s joint and apple tart. Alas! that cooking is an art still unknown in our dear old England. We sit at table only by Nature’s necessity—not to enjoy the kindly fruits of the earth as do other nations.

Yet what could we expect of the ’Ammersmith charlady who looked after us?—and who, by the way, probably looked after her own pocket as well.

The bachelor’s housekeeper is always a fifteen puzzle—twelve for herself and the remaining three for her employer. As sure as rain comes in winter, so does the smug and sedate female who keeps house for the unfortunate unattached male place the onus of housekeeping bills upon him and reap the desserts of life for herself.

On that particular evening I felt very tired, for in the five days of my absence many business matters had accumulated, and I had had much to attend to.

Harry, who ate hurriedly—even gobbling his food—told me that he was taking Norah to the theatre, hence, after dinner, I was left alone. I read the evening paper when he had left, and then, at eight o’clock, stretched myself, for it was time that I went out to my uncle’s.

The evening was cold and bright, with twinkling stars which on air-raid nights in London would have caused much perturbation among average householders and their families.

Our “Kaiserin” had gone home, so I rose, put on my overcoat, switched off the lights and descended the stairs to Hammersmith Bridge.

Thus, as you, my reader, will realize, I went out in the manner of a million other men in London on that particular night of Wednesday, the seventh of November.

And yet all unconsciously I plunged into a vortex of mystery and uncertainty such as, perhaps, no other living man has ever experienced.
