Newly-married and living in England, young American Sally Bowen receives a letter from a friend in the U.S. expressing concern for surprising recent developments: “It must be dreadful to be so far away from home and have your aunt confess that she poisoned her husband“. The only problem is, the letter fails to mention which of Sally’s seven aunts is the poisoner — and with no news agencies open until the following day, Sally doesn’t know who to contact for details…suppose, after all, she asks the poisoner themself? So her husband Peter convinces her to tell him to story of the family, suggesting that he will be able to truffle out the solution and put his wife’s mind at ease.
