The sixth book in the Sunday Times bestselling, award-winning, Slough House series, featuring Mick Herron's much loved band of disgraced spies and their notorious leader, Jackson Lamb, 'the most fascinating and irresistible thriller series hero to emerge since Jack Reacher' (Sunday Times)

We're spies,' said Lamb. 'All kinds of outlandish shit goes on.'

Like the ringing of a dead man's phone, or an unwelcome guest at a funeral . . .

In Slough House memories are stirring, all of them bad. Catherine Standish is buying booze again, Louisa Guy is raking over the ashes of lost love, and new recruit Lech Wicinski, whose sins make him outcast even among the slow horses, is determined to discover who destroyed his career, even if he tears his life apart in the process.

And with winter taking its grip Jackson Lamb would sooner be left brooding in peace, but even he can't ignore the dried blood on his carpets. So when the man responsible breaks cover at last, Lamb sends the slow horses out to even the score.

This time, they're heading into joe country.

And they're not all coming home.
