War of Nerves

Seeking to crack down on organised crime, Foyle places Milner undercover in a building business, which leads them to racketeering at a shipyard. When an unexploded bomb lands on the yard, Royal Engineers attempting to dispose of the bomb discover a horde of money, and agree to share it amongst themselves, an act they regret when one of their numbers is abducted and murdered. Foyle must resolve the crime racket and investigate the murder, while supervising the visit to Hastings of a Communist agitator.
