The only thing to do with an annoyance that turns up just before a vacation trip to a lovely island off Greece is to pack it up and take it with you. Antonia Winfield, with well-bred British restraint, did this with her husband's niece, who was running away from a failing marriage. The ladies had something that attracted violence and it required the presence of both their husbands before it was over. In addition to a mystery tidied up, there is a marriage to save. It's been a winning combination of two forms for this author and she handles both well.
