February 2: Ken Wyman, son of bank president Morton Wyman of Carterville's wealthiest family, as well as the star reporter for the
Daily Blade (run by city editor Burton), is the mystery-man called the
Devil's Dagger. Dressed in a tuxedo and top hat, with a black mask and a red cape, the Devil's Dagger fights crime in the Midwestern city of Carterville armed only with a gun and a series of daggers he leaves as his calling card. He is assisted by the family chauffeur Pat Gleason, ex-prize fighter, who maintains and drives for him the
Speed Ghost, a high-powered car equipped with tinted bulletproof windows. The Devil's Dagger's chief enemy is gangster Jeff Marlowe. Wyman's girlfriend is Sandra Cole, daughter of Carterville's Mayor Cole. In his first public case, the Devil's Dagger saves scientist Prof. Simon Craig and his daughter Jean from Marlowe, who wants Prof. Craig's diamond-making machine.
