Cover is a variation of the cover of Dick Tracy Comics Monthly #40.
Original title of this story is "The Case of the Atomic Killers."
The following changes were made to this reprint due to Comics Code Authority restrictions:
Page 1, panels 8, 9: Wire opaqued on black line but color still shows where wires were
Page 2, panels 2, 3, 4, 6: Wires removed to take away inference that victim was electrocuted
Page 18, panel 5: Bullets are opaqued, but because of color plate, their path is still visible. Diet
Smith's is visible as a white space, even the outline was deleted from the black plate.
Page 18, panel 7: The part of the panel showing Irma shooting herself in the head has been replaced
with a narrow panel that has "BANG" running vertically.
Page 18, panel 10: "The water's bloody!" has been removed from the first word balloon. Second balloon
changed from "That's blood on my hands!" to "He's been shot!"
Page 19, panel 2: Irma's body outline has been removed, but the color still prints.
Page 19, bottom caption: Changed from :Read the July issue of Dick Tracy" to "Turn the page quickly."
Page 20, panel 1: "Dick Tracy" logo changed to a descriptive caption.
