By the time that Colbeck and Leeming arrived at the site, lanterns and torches had been lit to illumine the scene. A few bonfires had also been started, burning the wood from the fractured carriages and the ruined wagons. Having met in a fatal collision, the two locomotives lay on their sides like beached whales, badly distorted, deprived of all power and dignity as they waited for cranes to shift their carcases. A knot of anxious people had gathered around each iron corpse, men for whom the destruction of a locomotive was tantamount to a death in the family.

As they picked their way through the debris, the detectives presented a curious contrast. Colbeck, the unrivalled dandy of Scotland Yard, was a tall, handsome, elegant man who might have stepped out of a leading role on the stage. Leeming, however, was shorter, stockier, lumbering and decidedly ugly. While the inspector looked as if he had been born in a frock coat, cravat, well-cut trousers and a top hat, the sergeant seemed to have stolen similar clothing without quite knowing how to wear it properly.

They soon identified the man they had come to see. Captain Harvey Ridgeon was the Inspector General of Railways, a job that consisted largely of investigating accidents throughout the system. He was standing near the two locomotives, talking to one of the many railway policemen on duty. Colbeck was surprised to see how young he was for such an important role. Ridgeon's predecessor had been a Lieutenant-Colonel who, in turn, had been preceded by a Major-General, both in their fifties and at the end of their military careers.

Ridgeon, however, was still in his thirties, a fresh-faced man of middle height with an almost boyish appearance. Yet he also possessed a soldier's bearing and a quiet, natural, unforced authority. Like all inspector generals, he had come from the Corps of Royal Engineers and thus had a good understanding of how the railways were built, maintained and run. When the detectives reached him, he had just parted company with the railway policeman. Colbeck performed the introductions. Though he gave them a polite greeting, Ridgeon was less than pleased to see them.
