3x1 - The Chelsea Detective

Chloe Carmichael, former popstar and one-time darling of the tabloids, is found dead in her Chelsea mansion flat in the days leading up to Christmas. They first suspect a drug overdose, but forensics soon establishes that Chloe had been drowned in the bath. Max and the team must contend with a string of potential suspects, including her hard-bitten manager, a conniving journalist and a Tory MP. Each of them has a secret connecting them to Chloe, but who was it that killed her?
