The train carriages in the riverbed and adjoining swampy banks were no longer recognisable as railway coaches. Except for iron axles and wheels protruding here and there at impossible angles from the water, it was as if a series of wooden bungalows had been flung out of the sky, perhaps dropped from some American cyclone and smashed to bits. And then the bits looked to have been dropped and smashed yet again.

It seemed to Dickens as if no one could have survived such impact, such destruction, but screams of living sufferers—for in truth the injured far outnumbered the dead—began to fill the river valley. These were not, he thought at the time, human sounds. They were somehow infinitely worse than the moans and cries he had heard when touring overcrowded hospitals, such as the East London Children’s Hospital at Ratcliff Cross—which Drood had just mentioned—where the indigent and unclaimed went to die. No, these screams seemed more as if someone had opened a portal to the pit of Hell itself and allowed the damned there to cry out one last time to the mortal world.

Dickens watched a man stagger towards him, arms outstretched as if for a welcoming hug. The top of the man’s skull had been torn off rather the way one would crack an eggshell with a spoon in preparation for breakfast. Dickens could clearly see the grey-and-pink pulp glistening within the concave bowl of splintered skull. The fellow’s face was covered with blood, his eyes white orbs staring out through crimson rivulets.

Dickens could think of nothing to do but offer the man some brandy from his flask. The mouth of the flask came away red from the man’s lips. Dickens helped him lie on the grass and then used the water in his top hat to clean the man’s face. “What is your name, sir?” asked Dickens.

The man said only, “I am gone,” and died, the white eyes continuing to stare up at the sky from their bloody pools.

A shadow passed over them. Dickens whirled, sure—he told me later—that it would be Drood, the apparition’s black cape widening like a raven’s wings. But it was only a cloud passing between the sun and the river valley.
