The Catch By Mick Herron

If life in the Intelligence Service has taught John Bachelor anything, it’s to keep his head down. Especially now, when he’s living rent-free in a dead spook’s flat. So he’s not delighted to be woken at dawn by a pair of Regent’s Park’s heavies, looking for a client he’s not seen in years. 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.
