Glasgow, 1989. James Addison, aka Addie, has been a very busy man. Wanted for every type of crime for over a decade, there is only one hitch - he has never been seen, let alone caught. So, who or what is Addie? Does he even exist?

When a small-time moneylender pimp is shot down on a Glasgow street, it seems to be just another gangland murder. But not for Andy Grimes, overseer of much of the city's prostitution, drug dealing and protection rackets - and the dead man's brother. When word leaks out that Addie is the killer, Grimes calls in his police allies and musters his troops. On the case is DCI Alex Birse, and old-time cop, as crooked as he is vicious. He has been after Addie for years and never got close.

As the streets of Glasgow heave with police and gangsters, over in Berlin the Wall is coming down. At this time of great change, opportunity and uncertainty, the two cities are linked by loot – Bearer Bonds to be precise. Back in Glasgow, while pulling a scam on an old Jewish couple, one of Grimes' men, Angie the Gopher, finds a biscuit tin full of Bearer Bonds issued in Germany before the Second World War. Angie smells money – the bonds could be worth millions – and he scuttles back to tell his boss. Now the chase is on.

Who gets the bonds? How much are they worth? Who perishes along the way? For the answers you'll have to rely on Addie. But can they catch him? The last line will reveal all . . . maybe.
