A very good mystery. The story is told by two women twenty years apart. Beatrice is working at the First Cleveland Bank in 1978 and starts unraveling mysterious goings on involving safety deposit boxes. In 1998, Iris, is assigned by her employer to survey the inside of same bank building that was suddenly closed overnight 20 years before. She makes many discoveries which may or may not include a dead body. Many keys are found and wondered about and she also uncovers information about Beatrice and becomes ever more curious about what happens to her. Beatrice is a very likable character and her part of the story flowed well and was more interesting to me. Iris is a totally unlikable character, rather a self absorbed, whiny brat. Her part of the story brought the 5 star rating down to a 4. Way too much time was spent on her drinking and hangovers, her dissatisfaction with her job and life on whole. The mystery kept me coming back to the finish and overall I enjoyed the book and will keep it in my library.
