London, 1997. A series of baffling murders. A web of political corruption. DC Ruth Hunter thinks she has the brutal killer in her sights, but there's one problem. He's a Serbian War criminal who died five years earlier and lies buried in Bosnia. When Detective Constable Ruth Hunter is called to the death of a pensioner in South London, she becomes convinced that it is not as routine as it first appeared. There are links to the death of another pensioner which suggest a link back to the Bosnian War of the early 1990s. With the investigation thwarted at every turn, Ruth soon realises she may have stumbled upon a political cover-up in the lead up to the 1997 General Election. As she races against the clock, Ruth believes the man she is tracking is a Serbian War criminal who supposedly died in Bosnia five years earlier. Can Ruth find the notorious 'Butcher of Strigova' before he murders again to cover his tracks?
