There are certain days in our lives which, as we recall them, seem to detach themselves from the general sequence as forming the starting-point of a new epoch. Doubtless, if we examined them critically, we should find them to be but links in a connected chain. But in a retrospective glance their continuity with the past is unperceived, and we see them in relation to the events which followed them rather than to those which went before.
Such a day is that on which I look back through a vista of some twenty years; for on that day I was, suddenly and without warning, plunged into the very heart of a drama so strange and incredible that in the recital of its events I am conscious of a certain diffidence and hesitation.
The picture that rises before me as I write is very clear and vivid. I see myself, a youngster of twenty-five, the owner of a brand-new medical diploma, wending my way gaily down Wood-lane, Highgate, at about eight o’clock on a sunny morning in early autumn. I was taking a day’s holiday, the last I was likely to enjoy for some time; for on the morrow I was to enter on the duties of my first professional appointment. I had nothing in view to-day but sheer, delightful idleness. It is true that a sketch-book in one pocket and a box of collecting-tubes in another suggested a bare hint of purpose in the expedition; but primarily it was a holiday, a pleasure jaunt, to which art and science were no more than possible sources of contributory satisfaction.
