This Is Murder

One evening: Sam Moraine, shrewd and genial advertising executive, sat playing poker with District Attorney Phil Duncan and his chief Criminal Investigator, Barney Morden.
The next night: Sam found himself out on a pitching yacht paying ransom for a seasick girl named Ann Hartwell, only to be arrested the moment he set foot on land, because federal agents thought he knew too much about the kidnapping.
The following night: He found himself stumbling over a corpse in a strangely dark house, with his very frightened secretary, Natalie Rice, subbing desperately at his side.
The rest of the week: Night and day, Sam Moraine was involved in everything his advertising. He was in turn detective, politician and suspected murderer. The role of murderer seemed about to stick, when the unexpected happened.
A smashing Grand Jury scene climaxes this exciting murder mystery. It’s built around the experience of a mean-in-the-street caught unwittingly in the greasy cogs of a crooked political machine, and of how he extricates himself.
