Why should the devil have all the best tunes?The Salvation Army has come prancing and singing from the slums of London to the poorest quarters of Oxford, but along with its red hot gospel preaching and music hall songs it brings a prohibition message which sparks immediate opposition and violence. An Army soldier – an ex-drunk – is brutally killed and a note suggests that the Salvation Army’s shadowy enemy, the Skeleton Army, is responsible. With the police unwilling to come between the two forces, Non Vaughan, aspiring journalist and great hope of the Oxford women’s college movement, and Basil Rice, Jesus College fellow and union-sanctioned guardian of the dead man’s family, are compelled to investigate.
