Instrument of Slaughter

1916. Inspector Marmion and Sergeant Keedy are assigned to the case when the body of a young conscientious objector is found bludgeoned to death. Public sympathy is lukewarm for conscientious objectors and some people even claim that a "conchie" deserves to die if he won't fight for his King and Country. As the detectives identify one suspect, others pop up in the most unexpected places. Everyone speaks well of Ablatt but is he really the saint they describe? Marmion and Keedy have to dig deep in order to unearth the instrument of slaughter and the person who wielded it.
