Death dues

the long version

"When local loan shark John 'Jaws' Harrison is found with his skull caved in in an alleyway backing on to rundown Primrose Avenue, DCI Joe Rafferty, and dour sidekick Dafyd Llewellyn, imagine the case will be easily solved. Armed with a list of local debtors, they begin their investigations. But they hadn't counted on the apparent consensus of silence amongst the residents most of whom had good reason to want Jaws dead."--Publisher description.
