CANNES, France (AFP) - “Trainspotting” author Irvine Welsh said Sunday he is adapting his acclaimed novel “Crime” for television, the first time one of the controversial Scottish writer's books will make the leap to the small screen.

The story of a cocaine-snorting alcoholic Edinburgh detective who runs into even more trouble when he goes on vacation to Florida is widely regarded as Welsh’s best since “Trainspotting,” with the Guardian calling it a “triumph.”

Having had his world turned upside down by a child abuse case in his native city, Detective Inspector Ray Lennox runs into a pedophile ring protected by corrupt police almost as soon as he arrives in Miami.

“The story is one of a classic journey from darkness into light, and despite the troubling subject matter, I think an uplifting one,” Welsh said as the series was launched at MIPCOM, the world's biggest entertainment market in the French Riviera resort of Cannes.

Scottish actor Dougray Scott of “Mission Impossible” and “Taken” fame has been signed to play Lennox.

Producer Tony Wood said the drama is “Welsh’s toughest yet most life-affirming to date.”

He said the series would be shot mostly in Florida intercut with flashbacks to the previous child abuse case Lennox investigated in Edinburgh “providing a stark contrast between the glistening paradise of the Sunshine State and Welsh‘s beloved sordid, infernal (home) city.”

Wood, head of Buccaneer Media which made the crime drama “Marcela” for Netflix, said Welsh is “a true literary buccaneer whose work defines our generation. It’s thrilling to be bringing talent of this caliber to television drama.”

He said Welsh was writing the series’ six hour-long episodes with his longtime screenwriting partner Dean Cavanagh.
