Continuing in the popular vein of reprinted comic strips, St. John published comic books of such gag strips as "Moon Mullins" and "Nancy", and of the NEA syndicate's private detective adventure strip "Vic Flint". This hardboiled fiction by the pseudonymous Michael O'Malley (writer Ernest Lynn and others) and artists Ralph Lane, Dean Miller, Art Sansom and John Lane, was reprinted in the comic books "Vic Flint" (#1–5?, Aug. 1948 – April 1949); all but the first issue of "Fugitives from Justice" (#1–5, 1953); and some issues of "Authentic Police Cases" (#1–38, 1948–1955).
