Inspector Alan Banks mystery 21 : Children of the revolution

A disgraced college lecturer is found murdered with £5,000 in his pocket on a disused railway line near his home. Since being dismissed from his job for sexual misconduct four years previously, he has been living a poverty-stricken, hermit-like existence in this isolated spot. There are many suspects, mostly at the college where he used to teach, but Inspector Banks soon becomes fixated on Lady Veronica Chalmers, who appears to have links with the victim going back to the '70s at the University of Essex, then a hotbed of political activism. When Banks suspects that Lady Chalmers is not telling him the whole truth, he pushes his inquiries a bit too far. Warned about this by his superiors, Banks must continue to conduct his investigation surreptitiously, under the radar.
