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.

Benny could be anywhere, provided it serves alcohol. So John sets out on a reluctant trawl through the bars of the capital, all the while plagued by the age-old questions: Will he end up sleeping in his car? How many bottles of gin can he afford at London prices?

And just how far will Regent's Park go to prevent anyone rocking the Establishment's boat?
