The Wrong Doyle

Tim Doyle comes home from Europe and the wreckage of his marriage when the uncle who raised him dies and leaves him the family crazy-golf course. It's a wreck and Tim thinks he'll probably sell it, until the wrong people start nosing round and encouraging him to get on with the sale. Encouragement turns to pressure, and Tim starts to wonder why. Is it all to do with long-rumoured pirate treasure his pirate ancestor is reputed to have left somewhere?
