To those who don’t really know her, Kate Henderson’s life must seem perfectly ordinary. But she is in fact a senior MI6 officer, who right now is nursing the political equivalent of a nuclear bomb. While heading up the Russia Desk of the Secret Intelligent Service, one of Kate’s undercover operations has revealed some alarming evidence. Evidence that a senior UK politician is a high level Russian informer.

Determined to find out who it is, Kate must risk everything to get to the truth. Until a young woman is brutally murdered as a consequence, which puts Kate and her team under the spotlight.

With blood on her hands, her reputation to uphold, her family hanging by a thread and a leadership election looming, Kate is quickly running out of options and out of time.
