A houseboat on the banks of the Thames may seem like an unlikely dwelling for a shrewd murder detective, but this is where DI Max Arnold likes to call home. Chelsea might be London’s wealthiest borough, with its opulent mansions and fast cars for the mega-rich, but it’s also a place of contradictions with sky-high tower blocks and a dark underbelly.

A place where people lie, cheat, steal – and commit murder.
