The Darkest Goodbye (Dsi William Lorimer)

When newly fledged DC Kirsty Wilson is called to the house of an elderly woman, what appears to be a death by natural causes soon takes a sinister turn when it is revealed that the woman had a mysterious visitor in the early hours of that morning - someone dressed as a community nurse, but with much darker intentions.

As Kirsty is called to another murder - this one the brutal execution of a well-known Glasgow drug dealer - she finds herself pulled into a complex case involving vulnerable people and a sinister service that offers them and their loved ones a 'release'.

Detective Superintendent William Lorimer is called in to help DC Wilson investigate and as the body count rises, the pair soon realise that this case is about to get more personal than either of them could have imagined . . .
