For three years, I trusted my husband’s weekly visits to my sister. Then our daughter mentioned something that didn’t add up. One Friday, I decided to learn the truth.

Karen lived alone in a modest split-level house about twenty minutes away. Her plumbing had always been a running joke between us. Old pipes, shifting foundations, constant leaks under the basin. Whenever I asked if she finally called a professional, my husband would just shake his head and smile.
