It’s a forbidden story, all right - of Monte Carlo! And Paris. They just abounded with forbidden stories, and spicy ones as well: “Banned by Continental Police because it tells too much.” Sure. A summary:

Margot Le Blanc loses her small fortune at Monte Carlo and makes the acquaintance of Hugh Kildair, an artist, who hires her as a housekeeper. A gang of thieves set a trap for Kildair when they find that he knows a mathematical system guaranteed to win at the gambling table. The gang is foiled by the arrival of the police; and Kildair, realizing he has fallen in love with Margot, marries her.

Robert Service wrote the book, eh? He was mostly known for Yukon yarns, not continental romps. Schulberg, the producer, had Bow under contract - a nice asset, but not enough. A year after this picture, Preferred went bankrupt, and Schulberg went over to Paramount. But when she left Paramount in 1931, he said, paraphrasing wikipedia, Schulberg went out too. Never seems like he scaled the heights again - wikipedia says in “1950 he unsuccessfully offered his services in the film trade papers.” He was supported in his pater years by his son, who would serve in WW2, was one of the first soldiers to liberate a concentration camp, and subsequently did a little writing himself.
