New from New American Library: Clubbed to Death: A Dead-End Job Mystery by Elaine Viets.
About the book, from the publisher:
Helen Hawthorne's latest dead-end job is in a country club's complaint department, dealing with the gripes of the rich and spoiled. Then Rob, her deadbeat ex-husband, sails back into her life aboard the yacht of his new lady, Marcella—known as the Black Widow for her string of dead spouses. The next day Rob's reported missing. If the Black Widow has such a murderous reputation, then why is Helen led from the club in handcuffs?Visit Elaine Viets' website.
When Marcella helps Helen get released, the two form an uneasy alliance to find out what really happened. Helen's barely begun digging when a club patron is discovered beaten to death with a golf club —his membership permanently expired. Someone got more than a little teed off and it's up to Helen to get to the truth—without getting clubbed herself...
