The Millionaire Waltz by Anthony Quinn

Against a backdrop of thuggish blackmail, constricting high society and a London still fragile from the war, Edie Greenlaw is trying to decide what she wants from the world. The closer the prospect of marriage with her handsome war hero fiance becomes, the less fulfilling it seems. Defying caution she goes to the aid of a friend and entangles herself in a dangerous demi-monde of sexual extortion and violence.
The Millionaire Waltz revisits characters and places that will be familiar to readers of Curtain Call, such as the outrageous theatre critic Jimmy Erskine, the penniless emigre pianist Laszlo, and the actress Nina Land, whose first encounter here with Edie becomes a vital friendship on stage and off. It enlarges a fresco of interwar London in all its glamour, its excitement, and its uncertain shadows.
