Previously published as The Jazz Files. Poppy Denby moves to London in 1920, gets a job initially as an assistant to a newspaper editor, then quickly becomes an investigative reporter looking into an old murder and a disappearance within suffragette circles. Her aunt, a noted actress and suffragette, is somehow linked to the case. Poppy is an appealing character who gradually learns what she is capable of accomplishing. The plot was rather unbelievable - it seems unlikely Poppy would have so much responsibility as a journalist in her first job ever, and she doesn't really solve the mystery as much as stumble upon the solution. Interesting look at 1920s London and the effect of war and the Spanish influenza on society. Thanks to the publisher and NertGalley for the ARC.
