Perhaps the unimaginable began when he was clambering down the steep embankment. Suddenly appearing next to him was a tall, thin man wearing a heavy black cape far more appropriate for a night at the opera than an afternoon’s voyage to London on the tidal train. Both men were carrying their top hats in one hand while grabbing at the embankment for balance with their free hands. This figure, as Dickens later described to me in a throaty whisper during the days after the accident when his voice “was no longer my own,” was cadaverously thin, almost shockingly pale, and stared at the writer from dark-shadowed eyes set deep under a pale, high brow that melded into a pale, bald scalp. A few strands of greying hair leapt out from the sides of this skull-like visage. Dickens’s impression of a skull was reinforced, he said later, by the man’s foreshortened nose—“mere black slits opening into the grub-white face than a proper proboscis” was how Dickens described it—and by small, sharp, irregular teeth, spaced too far apart, set into gums so pale that they were whiter than the teeth themselves.

The author also noticed that the man had two fingers missing—or almost missing—on his right hand, the little finger and the ring finger next to it, as well as a missing middle finger on his left hand. What especially caught Dickens’s attention was the fact that the fingers had not been cut off at the joint, as is so often the case in an accident to the hand or subsequent surgery, but appeared to have been severed halfway through the bone between the joints. “Like tapers of white wax that had been partially melted,” he told me later.
