Will Slater, a London lawyer, cannot trust anyone he knows. Under suspicion from both the police and SO15 for two murders and running a business of supplying arms to terrorists, he must find out who has betrayed him. His enquiries make him a target as he finds himself caught between an Eastern European gang of arms dealers and whoever is behind the whole operation. His journey takes him to the Highlands of Scotland, Mallorca and the Virgin Islands before culminating in London, where the truth is finally revealed.
