Phryne Fisher loves dancing, especially with gorgeous young Simon Abrahams. But Phryne's contentment at the Jewish Young People's Society Dance is cut short when Simon's father asks her to investigate the strange death of a devout young student in Miss Sylvia Lee's East Market bookshop.
Miss Lee has been arrested for the murder, and Phryne believes that she is a very unlikely killer. Investigation leads her into the exotic world of Yiddish, refugees, rabbis, kosher dinners, Kadimah, strange alchemical symbols, and chicken soup.
With help from the old faithfuls Bert and Cec, her taxi driver friends; her devoted companion Dot; and Detective Inspector ""Call me Jack"" Robinson, Phryne picks her way through the mystery. She soon finds herself at the heart of a situation far graver and more political than she at first appreciates.
And all for the price of a song...
