Cuts Both Ways (DI Rob Marshall 9, Paperback)

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.

Cuts Both Ways continues the Rob Marshall series, this time on the streets of Edinburgh and London rather than the lanes of Scottish Borders, and introduces DI Sam Winter, whose own series starts in May 2026.
