City walls

The search for a fugitive embezzler leads Amos Walker to Cleveland, where he is hired by Emmett Yale, a leading figure in the electric car industry, to investigate the murder of his stepson. Yale believes that his stepson's hitman is connected to Clare Strickling, a former employee, and his attempts to silence whispers that he has bought illegal insider-trading information. Walker shadows Strickling to a private airfield as he attempts to flee the country--only to then witness his murder. The twisted web of lies and deceit surrounding both deaths forces Walker to question the motivations of everyone he encounters, from Major Jack Flagg, an elderly barnstormer, Palm Volker, the attractive aviatrix who runs the airfield, Candido, a surly maintenance worker employed by Palm, and Gabe Parrish, a retired boxer. Naturally, everyone has secrets to keep--but the truths lurking beneath the surface this time may make this Walker's final case.
