Read this book! I did, taking advice from someone rather more trustworthy than I - Philip Pullman, no less, who was asked by a child at the Hay Festival if he ever read anyone else's books, and replied earnestly, yes, he was reading a great one just now - Aberystwyth Mon Amour.
OK, coming from Mid Wales and knowing all the places helps, but even if you didn't this would be just such an enjoyable read. It combines at least three levels of brilliance: it is a breath-takingly funny spoof on Chandler, or maybe even on Mickey Spillane - it gets pleasantly trashy in places. It is also a spoof on Welsh culture, and the wealth of in-jokes there is amazing. Secondly, its very surreal and black comedy cloak a plot which, dammit, is actually quite exciting - I wanted to know whodunnit! And thirdly, there are moments of real tenderness and insight into the deeper aspects of human emotions - love, sex, war, guilt. Oh, and best of all, a totally accurate and identifiable-with perspective on bastard P.E. teachers, may they all rot in hell.
I completely loved it, and read it in just two sittings. A truly remarkable first novel.
