If it hadn't been for the dog, Jo Patterson would never have overheard that bizarre snatch of conversation on the grouse moor. A year ago Jo didn't know a grouse from a Rhode Island Rooster. Now she's up to her eyebrows in mud because a day's labour on the shoot will earn her a precious 20 and an even more precious few hours of contact with humanity. If she hadn't gone on the shoot she wouldn't have remembered that conversation about security consultants when she discovers that her soon-to-be-ex-husband may have sold their business for much less than it's worth. And if she hadn't remembered the conversation she would never have kicked over the ant's nest of trouble . . .
