Super-Mystery Comics v7 #4

This anthology issue contains multiple stories. One tale involves a freight yard robbery where two men attempt to stop a moving train; when they jump to escape, the train crashes and they flee but later plan to back the money up to the freight yards. Another story features detectives investigating a book store owner for falsifying purchase records and hiding profits, discovering a discrepancy between his ledger and shipping records before confronting him about embezzlement. A third story involves Kayo Kitzel's training quarters, where a manager discusses giving a slugger medicine to prevent him from fighting, leading to a scheme involving ring toss and ultimately resulting in violence when one character confesses to murder out of fear and anger. The issue features the typical crime and mystery-themed stories characteristic of Golden Age comics, presented across its 16 extra pages.
