Rules, Regs and Rotten Eggs (Harriet Martens Mysteries)

Detective Superintendent Harriet Martens has resolved to resign after the new Assistant Chief Constable at the head of the CID has made her feel somewhat inferior in her job. However, her thoughts of resignation are abruptly interrupted when the pro-hunting politician Robert Roughouse suspiciously collapses during one of his vehement speeches at an anti-hunting demonstration. Sensing that someone has deliberately attempted to murder Roughouse, and seeing an opportunity to prove her worth to the ACC, Detective Martens determinately takes charge of the investigation.
