Detective Comics

Detective Comics is an American comic book series published by Detective Comics, later shortened to DC Comics. The first volume, published from 1937 to 2011 (and later continued in 2016), is best known for introducing the superhero Batman in Detective Comics #27 (cover-dated May 1939).

A second series of the same title was launched in the fall of 2011, but in 2016, reverted to the original volume numbering. The series is the source of its publishing company's name, and—along with Action Comics, the series that launched with the debut of Superman—one of the medium's signature series. The series published 881 issues between 1937 and 2011 and is the longest continuously published comic book in the United States.

In this early Batman tale, Bruce Wayne's fiancee Julie Madison falls under the hypnotic spell of "the arch-criminal known as the Monk!" Bruce takes Julie to see a doctor, who offers the not-so-solid medical advice to travel to Hungary, "land of history and werewolves."

Bruce is understandably not on board with that plan (he correctly guesses that the doctor is also hypnotized), but when Julie travels to Europe anyway, he climbs into his flying batarang and follows her across the ocean. There he discovers that the Monk has plans to transform Julie into a werewolf and make her his slave.

Detective Comics # 758-760
The Hatter shuns the usual means of technology, and instead starts using mind-warping drugs to get at his victims. And who are his victims? None other than the Gotham City Police. The Hatter slips the drugs into their coffee, doughnuts, tea, and so forth, discreetly...and within a very short amount of time, at least half the police force is under his spell. Batman must fight against time to free the cops from the Mad Hatter's control, before Gotham City completely plunges into chaos.
