Slough House

At Slough House - MI5’s London depository for demoted spies - Brexit has taken a toll.

A year after a calamitous blunder by the Russian secret service left a British citizen dead from novichok poisoning, Diana Taverner is on the warpath.

In MI5 a scandal is brewing and there are bad actors everywhere. A key member of a Downing Street think-tank has disappeared without a trace.

Meanwhile her Russian counterpart has unexpectedly shown up in London but has slipped under MI5's radar.

Claude Whelan, who was once head of MI5, has been tasked with tracking her down. But the trail leads him straight back to Regent’s Park itself, with First Desk Diana Taverner as chief suspect. Has Taverner overplayed her hand at last?
