The Edge (Unabridged‪)‬

A high-class, transcontinental horse-racing junket should be an idyllic getaway for the super-rich. But one passenger on this train is a sociopath – a genius at blackmail and criminal corruption – and he plans to take everyone for everything they've got.

To the Jockey Club, the racing world would be a better place without Julius Apollo Filmer. An expert in corruption with a devastating line in witness intimidation – and a slippery character to put behind bars.

Baffled, they call in undercover security agent Tor Kelsey to keep an unflinching eye on Filmer and his associates. A mission that takes him from the finest of English racecourses to the wild Canadian interior – on a luxury transcontinental train journey to end them all.

On board, a troupe of actors are playing out a murder mystery for the amusement of their diamond-studded passengers. Ideal cover for a secret investigator with secrets of his own.

And better still for an ice-cool blackmailer for whom murder is just one of many options ...
