Famous Funnies #18

The issue contains two main stories. The first follows a warden dealing with criminals on the run who seek escape through a prison ship, with help from Molly and two smaller characters who offer assistance in foiling the criminals' plans. The second story features Space Mouse and his son Bob, who are recruited by a doctor to travel to Mars and manage insect hatcheries, only to discover the doctor has betrayed them to take the colony for himself—leading to a showdown where Space Mouse works with Bob and a cowboy character to thwart the doctor's scheme in a Western-style confrontation.
