Marriage is Murder (Jenny Cain Mysteries, No. 4)

Jenny Cain and police detective Geof Bushfield already had pre-nuptial jitters. Then a sudden wave of domestic violence rocked placid Port Frederick - in just two weeks, the husbands of three battered wives were shot dead. Homicide was all too familiar to Geof, but this was enough to make him want to quit the force. Except that none of the wives confessed - and none of the guns were found. As Geof searched for clues, Jenny uncovered a dangerous secret - a murderous obsession that threatened to tear Port Frederick apart!
