With “Europe [having] exploded”, crime-solving New York schoolteacher Hildegard Withers is holidaying in Los Angeles and, by dint of being recognised from a photo in the paper, is hired by a film studio as a consultant on a new film about Lizzie Borden. When, on her first day, the man in the office next to hers dies from a broken neck, Miss Withers becomes — for reasons that completed eluded this reader — convinced that he was murdered and sets about trying to find his killer. Thankfully, plenty of suspicious types present themselves for consideration, as the prospect of blackmail, secrets, and a general dissatisfaction with the victim’s comportment all float to the surface.
