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.

So when the man responsible breaks cover at last, Lamb sends the slow horses out to even the score.

Dieter Hess, an aged spy, is dead, and John Bachelor, his MI5 handler, is in deep, deep trouble. Death has revealed that the deceased had been keeping a secret second bank account - and there's only ever one reason a spy has a secret second bank account.

John doesn't know what secrets Benny Manors has stolen, but they're attracting the wrong attention. And if he's to save his own skin, not to mention safeguard his living arrangements, John has to find Benny before those secrets see the light.
