By Boris O'Hara. "Based on a screenplay by Howard Browne," so this appears to be a novelization of the "shattering 20th Century-Fox movie" the back cover implies is "now" out based on the...book? Doesn't matter. Either way, this is the story of "Al Capone's hate letter to the world...the most bizarre gangland slaying of all time..."
This fairly rare PB is in nice shape, comparatively mild toning to the pages, whose edge tint is still quite bright. The slim paperback's spine is not cracked; no writing or dog-ears inside. And this cover font can be my valentine any time.
