Loose Threads - the new laugh-out-loud crime novel from Martin Stewart

When Dr David Cairney goes missing on the way home from his retirement party, his wife asks ex-boxer and journalist Robbie Gould for help. Gould wants nothing to do with it . . .  but he needs the money. Soon he is plunged into a world of missing Kremlin diamonds and pre-digital espionage – all coded signals, orange peel and scraps of red thread.
