Jim Buchan and Jack Harvey were friends. But that was a long time ago. In Reichenbach Falls, the lives of these estranged men are thrown together again, then blown apart.

Wry and obsessive DI Buchan is a cop on the edge; suave and self-assured Jack Harvey is a best-selling crime novelist with the world at his feet.

As Buchan probes a 100-year-old cold case, the investigation takes him into the dark Jekyll-and-Hyde underworld of Edinburgh and on a parallel journey into the Scottish capital's literary past that leads him to question the very nature of his own existence.
