In Nobody Loves a Centurion, playboy sleuth Decius joins Caesar in Gaul, where the great general has come, has seen, but is having quite a hard time conquering. The Roman soldiers are pretty much stalled in their camp, which gives officers with a sadistic bent the opportunity to browbeat, actually beat, and to think up generally cruel things to do to the men under them. It's shocking, but not surprising, when the worst of this crew is murdered and a young man, son of one of Decius's family's friends, is accused of the crime. Caesar challenges Decius that the only way he can save the youth from execution is to prove that another is guilty.
