The Big Heat

Murder was in the air. A cop had killed himself, and every crook in town knew that would be sure to bring on THE BIG HEAT.
Why did they fear a dead man? Dave Bannion, homicide sergeant, fought for the answer to that question. He got it... Then the big heat came.
The dead man was a police clerk who shot himself for no obvious reason. That was Bannion’s first judgment, until a girl named Lucy presented a quite different picture of the dead man from the one he had shown to the world — and to his fastidious, glacial wife.
Bannion’s chief, Lieutenant Wilks, wanted the case closed and speculation ended — quickly and tightly. So did Max Stone and Lagana who held the city in a sinister, underworld grip. Why did they fear a dead man?
In this story of grim excitement, pathos and dramatic surprise, one of our foremost mystery writers presents the outstanding murder novel of the season.
