The first book in M C Beaton's Edwardian Murder Mystery series. After a brief dalliance with the Suffragette movement, Lady Rose Summers' debut season in London society is a complete disaster. Rose's father suspects that her fiancé, Sir Geoffrey Blandon, is a first class scoundrel and calls in Captain Harry Cathcart to investigate. But when a malicious guest is found dead in suspicious circumstances, Rose becomes far more interested in discovering the truth than in landing a more appropriate suitor.
