I agreed, rather absently I will admit. As I took a swallow of the glorious liquid, it occurred to me that some part of the back of my mind was braced for a ring of the telephone or a furious pounding on the door. The visceral mistrust of leisure was perhaps understandable: Twice in the past six months the outside world had crashed in on us; indeed, we had been similarly seated before the fire one evening a scant two months earlier when an investigation literally fell into our arms, in the form of an old friend with a bloodied head. It was not yet midnight, and I had no faith in our stout oaken door to keep out surprises of the kind Holmes tended to attract.

However, pleasantly enough, no pounding fist came to trouble our companionship or, later, our slumber, and we rose early the next morning, fortified ourselves with one of Mrs Hudson’s hearty breakfasts (this one even more elaborate than usual, to make up for her being cheated of preparing the dinner for this, my twenty-fourth birthday), and bundled into our warmest clothes for the sleet-drenched trip to London. We rode the train in silence, taken up with our thoughts and with the newspapers, both as cheerless as the landscape outside the windows. Foot-and-mouth disease, the rising Seine, and doomsayers with apocalyptic predictions on both sides of the Atlantic, set off by the recent Labour victory.

Grimmer yet was the real reason for our visit to the great city. We had no end of business there, of course, from a long-delayed appointment with the bank manager to calling on a noble family in order to follow up on our most recently concluded investigation, but in truth, we were there to see Holmes’ brother Mycroft, whose health was giving, as the euphemism goes, cause for concern.

He was home from hospital already, although the doctors had strongly advised against it, and embarked on his own programme of therapy. I personally wouldn’t have thought a near-starvation diet of meat and red wine combined with long hours of vigorous calisthenics would be the best thing for a shaky heart, but not even Holmes’ arguments made much of an inroad on Mycroft’s determination. We had maintained a closer contact with him than usual over the past week and a half, none of us voicing the thought that each visit could well be our last. We hurried through the day’s business, I listening with half an ear to the urgent recitation of calamity that trembled over the head of my American possessions, thinking only that, affection for my father or not, the time had come to rid myself of his once-cherished properties across the sea. I kept glancing at my wrist-watch, until finally with a sigh my solicitor threw up metaphorical hands, gave me the papers that required my signature, and allowed me to escape.
