BATMAN DETECTIVE COMICS (2024) HC VOL 03 THE COURAGE THAT KILLS

Criminals are a superstitious lot—something the Dark Knight has always used to strike fear into them in his fight for justice. But what if Gotham were a city without fear? Would its citizens find true freedom, or would they break under the inability to process deadly dread? That's exactly what Gotham's newest villain wants to find out.

A mysterious, weaponized virus is discovered—already with dozens dead. As the threat of a citywide attack grows, the investigation grinds to a halt when the Dark Knight himself is infected. Now a race against time begins: Batman must rely on the help of allies like Mr. Terrific and Superman to find answers before the virus takes total control of his body and mind.
