Monkey Puzzle in Bloomington, MN

Alan Westbrook and Kirsty Williams have been married for seven years and have been living comfortably in their cottage in the dales. They had hoped that their previous brush with MI5 had been forgotten until they receive a visit from an old acquaintance.
MI5 had decided to call in their debt and enlist the help of Alan and Kirsty to solve a rather knotty problem.
As things unfold, it is obvious that more of their past has returned to haunt them, but whom is behind it? That is the question, and can they solve the problem without endangering themselves and their friends and family?
An exciting thriller with a touch of humour.
