The Wood: 6

DI Zoe Finch has been in Cumbria long enough to know who's pulling the strings in organised crime, and who's helping them from within the police. But just as she's closing in on the evidence to prove it, she finds herself scrambling in the fallout from the murder of a key witness, and struggling to keep the case out of the hands of the very man she suspects of orchestrating it. Can the women rescued from a human trafficking ring help Zoe wrest back control of the investigation? And does a seemingly unrelated murder on the other side of the Lake District hold the key to bringing her enemies to justice? With the team thrust into unfamiliar roles and the whole station under investigation, the stakes have never been higher. Can Zoe and her team hold it together under mounting pressure?
