The BAFTA-winning hit returns as DI Sunny Khan and new DCI, Jess James, uncover the truth behind another historical murder. Human remains are discovered in a newly renovated period property in West London. But is this a murder dating back to the 1930s or has the body been disposed of in more recent times? Sanjeev Bhaskar is back to lead the team alongside Sinead Keenan who plays his new partner DCI James. The ghost of much-loved former colleague Cassie Stuart still hangs over the department - does Jess have the resolve, professionalism and spirit to live up to her much-admired and respected predecessor?.
