Orla Payne's brother disappeared 20 years ago and was presumed to have been killed by their uncle who sunsequently killed himself in the appropriately named hanging wood. Orla has recently returned to the Lake District and contacts the cold case review team but her drunken ramblings are not very coherent. Later she is also found dead and the case into her brother's death is reopened along with an investigation into her death.
This is the fifth in the Hannah Scarlett/Daniel Kind series and the third I have read. I really enjoyed this one and am going to hunt out the two that I have missed.
