Game of Stones

Cameron Beaumont's phone still rings to wake him at 3am even in Sheffield 20 years after he had to escape from South Africa during the violent death throes of apartheid.
Now it can't be the Special Branch on the other end of the line; but the silence provides no clues. Who is following him this time, and who is trying to frame him? He has made too many enemies to know. Could it be the police again, hoping to stop him writing about Hillsborough?
Does it have anything to do with what happened when he went back to South Africa to try to continue the struggle against apartheid? Can he decipher the trail of clues laid for him via references to the game of Go?
This is a story of loss, betrayal and revenge that builds to a violent climax and an unlikely reconciliation.
