One of the recencions on Suicide Pact - You First says this:

‘According to frontman Andy Cairns, Therapy?’s new album, Suicide Pact—You First, takes its title from a book called Five Days In Hell by English Kafka-esque author Rupert Thompson.’

Since I study languages I’ll have to read some english literature sooner or later anyway, but I can’t seem to find this book on the net. Is it possible they made a mistake, and meant ‘The five gates of hell’ by Rupert Thompson instead? As a big Suicide Pact - You First fan I’d like to read the book that inspired the title of it rather than some cheap chicklet I might find in some store (I live in Belgium so english books are slightly harder to come by), but I of course need to be sure before I spend any of my precious, dear money (not to mention time) :)
