Washington police knew he lived in a maze of political intrigue, surrounded by enemies. They knew, too about lovely Lynn Ash, secret lobbyist for the utility interests, who had been closely associated with Greer. But when they went to question her, they found she had been strangled to death in her car. The case of a stalemate until Colonel Primrose, sentimental gentleman sleuth, smoked out the killer in this breathless mystery novel of the nation's cosmopolitan capital.
