Death to Pay — Derek Fee

When can you stop looking over your shoulder?
The brutal murder of Lizzie Rice, the mother of one Belfast's most notorious Godfathers, threatens to ignite war on the streets of Belfast. As riots ensue, more bodies, killed in the same gruesome manner, start to pile up and it's clear that DCI Ian Wilson and the Murder Squad are dealing with a very dangerous serial killer.
Wilson needs to investigate both the past and his own present if he wants any chance of catching the killer.
A Debt to Pay is the third book in the Wilson series. If you like hard-boiled and compelling detective fiction, you are sure to find Wilson a character that you will identify with and like. Wilson investigates murder in the boilerhouse that is modern-day Belfast, a city still emerging from a violent past. In a situation where crime and politics are often intertwined, Wilson and his team must have their finger on the pulse of the city and tread a careful investigative path. Reviewers have likened Wilson to John Rebus.
