This is based on a novel by Craig Rice, who wrote several very funny mysteries involving the three main characters. (Rice also scripted a couple of the Falcon movies.) This movie is reasonably true to the spirit of the novels, though would have been better if Rice was more directly involved in its writing. Malone has featured in a few other movies, but Helene and Jake Justus (who were in all but one of the Malone novels) are oddly absent in the other movies. There was also a radio series and a TV series. A few months after this movie was released, Rice was featured on the cover of Time Magazine, the first mystery writer to be so honored.
