JSA: The Liberty Files is a comic book published by DC Comics. The writers were Dan Jolley and Tony Harris. The artists were Harris and Ray Snyder. The books were originally written as two separate two-issue stories; JSA: The Liberty File in 2000 and a sequel, JSA: The Unholy Three in 2003. They were published as a single volume collection in 2004. In 2012, an additional sequel entitled JSA: The Liberty Files - The Whistling Skull debuted, again with Tony Harris, and featuring B. Clay Moore as the writer. The series was created as part of DC's Elseworlds line, stories that are considered non-canonical. This series was based on characters from the Justice Society of America but portrayed them as covert government operatives in a World War II-era setting, rather than their traditional portrayal as superheroes fighting criminals. The Liberty File Part 1: "Brother Can You Spare a Mind?" Set in Egypt, 1942, the Bat (a.k.a. Batman) has been ordered to work with two new partners, the Clock (a.k.a. Hourman) and the Owl (a.k.a. Doctor Mid-Nite), as a group codenamed the Unholy Three. Their mission is to find Jack the Grin (a.k.a. the Joker), a smuggler who has stolen information about an unidentified German secret weapon. They are in a race with the Germans, who are also looking for Jack to recover the plans. They succeed and discover the German weapon is an "Übermensch" (translated: "superman"). Part 2: "...And the Clock Struck Midnight" The Owl, injured in the previous mission, is recovering in a hospital when he is killed by an enemy agent. The Bat and the Clock are sent to Switzerland to meet an agent who has information about the German Superman and to rendezvous with Terry Sloane, a former field agent codenamed Mister Terrific. A German agent, the Scarecrow, pursues them and kills the agents' Swiss contact. In a struggle with Scarecrow, Sloane's fiancée is killed. Sloane resumes his Mister Terrific identity and helps the Bat and the Clock pursue and kill the Scarecrow. They find out that the Superman, accompanied by Hitler and other Nazi leaders, has traveled to Egypt to spearhead a German military offensive. The Bat arrives in Egypt just as the attack is about to begin. He confronts the "Superman", who is revealed to be the Martian Manhunter. In addition to his other powers, the Manhunter is able to absorb another person's thoughts by
