Set in Miami, the novel follows the hardened but fragile Detective Ray Lennox as he flees to the city to take his mind off a harrowing child rape-murder case back in Edinburgh. It was proving too costly a prospect for producers, says Welsh, until he took the case itself and drew out the six-part series from there.
The author is no stranger to screens having had success in cinema with four adaptations of his novels, including the box office smash and decade-defining Trainspotting (1996). Although, he admits, “you can get a bit comfortable and keep trying to replicate it.”
