'Filth' sucks you deep into the disturbed, poetic, perverted, brilliant and fevered brain of Detective Sargent Bruce 'Robbo' Robertson. Bruce is in line for a big promotion to DI, and will stop at nothing to get it. Eliminating the competition with psychopathic precision, whilst indulging in his own sordid urges (booze, sex, cocaine and a bit of the old ultraviolence), it seems hard to make this character relatable or even that likeable. However, through Welsh's horrific but poignant stream-of-consciousness writing, Bruce is not only irresistibly interesting, but also tragically pitiable. As we hear Bruce's traumatic origins (narrated by the self-conscious tapeworm swimming through our misogynistic anti-hero's belly), he becomes less of an amoral Dracula and more like a miserable Frankenstein's Monster. For me, THIS was the most intriguing part of the story.
(SPOILERS)
The bastard son of the serial rapist 'The Beast' who raped his young mother, Bruce was treated as such by his father and pretty much everyone else who knew him. All they could see was the face of the demonic criminal who had disgraced an innocent young woman. As his younger brother was basked in attention and love, Bruce was abused, ignored and even forced to eat coal. The worst part for me was that Bruce didn't even seem to know why this was. He would look in the mirror, desperately looking for what everybody else saw in him that was so 'wrong', so 'sick', so 'filthy'. All he could see was a sad, little boy who seemed incapable of being loved by anyone. Going back to my 'Frankenstein' thing, I see The Beast as being the Doctor and Bruce being The Creature, something which should never have been given life, that would be destined to live a cursed life if it did, that would be hated, that would be feared, that would drive everybody who he cares for away from him. When Bruce visits his real father in prison and begins beating on him, I think it is less to do with what he did to his mother and more the fact that he brought him into the world in the first place. He resents his own life. As a result, like the Creature and Milton's Satan, 'evil became (his) good'. At the end of the book, Robbo's suicide seems to be a petty way of getting back at his ex-wife. In the recent film adaptation with James McAvoy, however, it seems more like a genuine cat of repentance and redemption, which I think fits in well with this backstory. He sees himself as 'wrong', which ultimately he must put 'right', by ending it... but, that's just my view.
The book was fantastic! I was a little disturbed by it at times (and even began questioning my own sanity during my reading of it), but it is a brilliant character study, a black comic tour-de-force and a brilliant introduction to Welsh's twisted, psycho-punk universe!... just try not too get too sucked into Robbo's head... it may be difficult to get out.
