Our hero, Detective Sergeant Bruce Robertson, is a cross between Harvey Keitel in Bad Lieutenant and John Belushi in Animal House. His task is to nab a killer who has brained the son of the Ghanaian ambassador, but bigoted Bruce is more urgently concerned with coercing sex from teenage Ecstasy dealers, planning vice tours of Amsterdam, and mulling over his lurid love life. He's also got a tapeworm, whose monologue is printed right down the middle of many pages. Here's one of this unusually articulate parasite's realizations: "My problem is that I seem to have quite a simple biological structure with no mechanism for the transference of all my grand and noble thoughts into fine deeds."
Welsh's real strength is comic tough talk and inventive slang. The murder mystery helps organize his tendency to sprawl, but the engine of his art is wry, harsh dialogue. At one point, his books hogged the entire top half of Scotland's Top Ten Bestsellers list--and half the buyers of Trainspotting had never bought a book before. The reason is not that Welsh is the best novelist who ever got short-listed for the Booker Prize. It is that he is that rarest of phenomena, an original voice. --Tim Appelo
"A snarling epic of a book...ugly, devastatingly funny, unremittingly nasty and pulls no punches... Don't dare miss it" (Scotsman)
"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)
