This moves -- moves is at its operative best -- from Cape Town to Johannesburg out into the dustier reaches of the bush with Land Rovers and jackals on the ground and Pipers and vultures overhead -- a change of scene for an action story loaded with more than guns. Jimmy Keogh, an engineer, becomes circumstantially involved with a black called Shack who has escaped from a prison island and who is anxious to rejoin Wilby who had promoted the cause, peacefully, before Sharpeville. Shack is in handcuffs; Keogh saws them off in a crushing procedure and delivers him to a former contact, Mayat, both devious and frightened. Justifiably since they have been spotted and kept under surveillance by two members of BOSS (Bureau of State Security) while on the other hand others formerly affiliated with Wilby are anxious to retrieve 14,000 pounds they later learn were converted into diamonds. Buried in a sinkhole, along with a man. Driscoll, a newcomer, tells an implosive story and you won't be able to hear yourself think. Or wonder whether it hasn't been overplotted? But it's well written and the publisher expectations are high -- it may snake its way like a brushfire.
