Actor turned thief Rafe Tyrrel knows where more than two and a half million pounds is hidden, the proceeds of a Royal Mail train robbery and a post office job, both the work of his Islington gang.

Now Rafe is in a high-security prison in Granchester. Detective Chief Inspector Martineau knows that every gang in England will want a cut of that money, and will try to get to Rafe.

One of Rafe's gang, Pilgrim, moves the rest of the men to industrial towns around Granchester - ready to spring Tyrrel and get their share. But will stylish Granchester 'businessman' Dixie Costello and his associates get there first?
