It's August and Gibraltar Hall hosts reality TV show I-Spy with Brenda as one of the contestants. Her Sanford 3rd Age Club friends arrive to welcome her back after a week's stay in the house. Inside, feelings run strong between the Housies. Arguments become heated. Then one of them is found dead. With cameras covering most of the house, no one could have gone near the victim without being seen. No one from the outside could have entered the house without being seen. It must be suicide. But Joe knows it was murder and he must persuade the police of that. It's a complex and maddening puzzle for the Sanford 3rd Age Club. Can they solve the impossible murder?
