DC Comics Graphic Novel Collection #19

In "null," Bruce Wayne spends Valentine's Day with Selina Kyle, but their evening takes a dangerous turn when he's captured by Poison Ivy. As the Holiday killer targets Salvatore Maroni's gang, Gotham's streets grow colder—both in temperature and in trust—while Batman, Alfred, and the city's protectors race to uncover a threat that blurs the line between justice and vengeance.

In "Der Riddler," Edward Nigma embraces his obsession with puzzles, transforming his genius into a criminal calling as the Riddler, challenging Gotham’s finest—including Batman, Robin, and Police Chief James Gordon—with a series of mind games that test wit as much as will. With the city’s unbenannter Bürgermeister and Harrison Eagle caught in the crossfire, the game begins, and the line between solver and solver’s victim blurs.

While Bruce and Dick are attending an art show, a woman arrives claiming to be the greatest criminal currently in Gotham. Her presence sends ripples through the city’s underworld, drawing the attention of Ivy’s gang, Dragon Fly, Silken Spider, and Tiger Moth—all of whom answer to a new, enigmatic force. As the night unfolds, the line between art and danger blurs, and the city’s most dangerous players begin to converge.
