Widow Sheila Malory has been looking forward to her stay at the Bodleian Library in Oxford as a chance to research wartime women writers and catch up with old friends from her college years, the one 'purely happy' time in her whole life. Her relaxing idyll is interrupted when a librarian, Gwen Richmond, is crushed to death beneath collapsed bookshelves. After the 'accident' proves to be murder, Mrs. Malory’s godson Tony, who also works in the library, asks her to help investigate. Gwen was manipulative and unpleasant, so there are no shortage of suspects. The dead woman’s World War II diary reveal dreadful truths that may lead to the killer; they will also force Mrs. Malory to revisit the past in a new and colder light. The second of Hazel Holt’s Mrs. Malory mysteries.
