Hi, please help A gang of young people (lads) spend time in a cafe annoying the owner. They then beat up a marine or navel man. There is also a love interest for one of the main characters... (Could be a cross dresser, not sure). I read this in 2002 but I think it's based in 1930's Any help would be greatly received... It's driving me nuts Regards Marek
