Just read one, Loose Head by some wanker called Jeff Keithly. Murder mystery about an English old-boy rugby team who go on tour to Vegas, get up to all kinds of disgusting shenanigans, and then one of the guys blackmails his mates and winds up dead. Plenty of sex, violence, humour, lots of on-field action, and it's actually surprisingly well-written. I think it's only available electronically -- I bought it on Amazon for my Kindle (
