Los Angeles, 1938. Former aspiring actress Lillian Frost is adjusting to a new life of boldfaced names as social secretary to a movie-mad millionaire. Costume designer Edith Head is running Paramount Pictures’ wardrobe department, but only until a suitable replacement comes along. The two friends again become partners thanks to an international scandal, a real-life incident in which the war clouds gathering over Europe cast a shadow on Hollywood.

Lillian attended the Manhattan dinner party at which well-heeled guests insulted Adolf Hitler within earshot of a maid with Nazi sympathies. Now, secrets the maid vengefully spilled have all New York society running for cover – and two Paramount stars, Jack Benny and George Burns, facing smuggling charges.

Edith also seeks Lillian’s help on a related matter. The émigré pianist in Marlene Dietrich’s budding nightclub act has vanished. Lillian reluctantly agrees to look for him. When Lillian finds him dead, Dietrich blames agents of the Reich. As Lillian and Edith unravel intrigue extending from Paramount’s Bronson Gate to FDR’s Oval Office, only one thing is certain: they’ll do it in style.

Renee Patrick's Dangerous to Know beguilingly blends forgotten fact and fanciful fiction, while keeping Hollywood glamour front and center
