Bert and Mamie take a cruise

"February 1939. Mamie Mason isn't enthusiastic when Bert, her husband of thirty years, persuades her to join him on an African cruise. Bert might be pining for adventure, but Mamie's perfectly content with her comfortable life in Hills Corners, Ohio. But once the couple board the glamorous SS Columbus, Mamie has to admit - much as it pains her - that Bert was right. Swimming in the pool, dancing under the stars, their own bedroom steward to serve their every whim . . . Mamie settles in and prepares to thoroughly enjoy all the sights that Africa has to offer, in the company of a motley collection of eccentric first-class passengers. Then Mamie witnesses something shocking - and her vacation takes a twist that neither she nor Bert could ever have predicted. Far from home, with a killer in their midst, the couple's only choice is to turn detective. But surrounded by Nazis, spies and passengers with secrets, how can they uncover the killer - enjoy their vacation of a lifetime - and make it back to Ohio alive?"--Publisher marketing.
