Senior moments are murder
(Book)

Imagine waking up in a place you didn't recognize, not remembering anything from the day before and then finding a dead body. Cantankerous octogenarian Paul Jacobson must solve a series of murders while struggling with the problems of his short-term memory loss. Paul learns about the homeless community, disreputable art dealers and the beach scene in Venice Beach, California, and must dance a geezer two-step to stay out of the clutches of the police and the bad guys.
