Detective Sergeant Bruce Robertson wants to wind down to Christmas with a week of sex and drugs in Amsterdam. The last thing he needs is a messy murder to solve.

"Welsh firing on all cylinders... The best thing he has done since Trainspotting" Sunday Times "It is surely a remarkable cultural moment when a reviewer is offered cash in a bar for an advance copy of a literary novel... Filth is a masterpiece...squarely in the classic line of classic scottish writing" Independent "Things are going well for Detective Sergeant Bruce Robertson. Promotion is in the offing, he's got all the booze and drugs he needs, and his various plots aimed at friends and colleagues seem to be working out. Robertson, compulsive and repulsive by turns, has only two problems. One is a case of racially-motivated murder on his patch. The other is that there's a nasty tapeworm in his gut and it seems intent on having its say... A brutally sustained achievement" Evening Standard "We're used to tough cops with non-PC attitudes, but Welsh trumps the lot with his evil-scheming, ball-scratching, foul-mouthed hero-with-haemorrhoids... Welsh's jet-black comedy at once entertains and appals... Gloriously grotesque" Esquire "A snarling epic of a book...ugly, devastatingly funny, unremittingly nasty and pulls no punches... Don't dare miss it" Scotsman
