Ben's sister is either Dorothy or Evelyn. Suppose Ben's sister is Dorothy. Then, Dorothy's husband is Carl. Then, Carl's sister is Evelyn. Since Dorothy, Carl, and Evelyn argued, Ben is the victim. However, Ben's wife has to be Evelyn, so Carl's sister is the victim's spouse. That means that Evelyn argued with herself. That is weird, so Ben's sister is Evelyn. Therefore, Carl's sister is Dorothy and Dorothy's husband is Ben. Also, Carl's wife is Evelyn. Since Evelyn, Ben, and Dorothy all argued, the victim is Carl.
