The Sibyl in Her Grave

Published posthumously, Caudwell's final Hilary Tamar mystery finds the androgynous Oxford professor and his (or her) coterie of junior barristers untangling a complicated case of insider trading and murder. While barrister Julia Larwood is mulling over a panicky letter from her aunt, Regina Sheldon, about taxes owed on certain recent investments, her colleague, Selena Jardine, is coincidentally advising Sir Robert Renfrews, chairman of Renfrews' Bank, on the mysterious leaking of top-secret business gossip that has somehow reached Aunt Regina and her two investment cronies. The conduit of information proves to be Aunt Regina's new neighbor, Isabella del Comino, a self-styled ""psychic counselor,"" who may be blackmailing one of two rising directors at the bank. Isabella's sudden death and the emergence of her pathetic but creepy niece, Daphne, raise concerns: did one of the bank directors murder Isabella, and will Daphne, or possibly even Aunt Regina, be next? Mining Barbara Pym country for tipsy vicars and high-strung spinsters, Caudwell has produced a droll, rather retro whodunit, updated only by the barest hint of same-sex dalliance. In addition, the young barristers have time to deconstruct wordy epistles from a suburban aunt and to natter on in stiff-upper-lip British diction about bookshelves and vacations as if they were back in the junior common room. It's all highly artificial, but Caudwell's crafty plotting and knowing wit will keep readers happily diverted. (July)
