Cuts Both Ways

Two murders. Two cities. One killer.

During the Edinburgh Festival, DCI Rob Marshall answers a call that lures him to Duddingston Loch, where he witnesses a woman drowning.

At the exact same time and hundreds of miles south in London, Met DI Sam Winter takes the exact same call – and can't save a man from burning to death near the Notting Hill carnival.

Someone is choreographing death across two cities, testing both detectives and forcing them to see what links the victims together — and themselves.

But when the calls turn personal, Marshall realises the next name on the list might be one of their own.
