This year’s 45th issue of Shogakukan’s Weekly Shonen Sunday magazine has announced that Gosho Aoyama’s Detective Conan manga will be on hiatus in issues 46 through 48 so the author can do research. The manga will return in the 49th issue on November 1, 2017.
Detective Conan has been running since 1994 and in August 2017, it became the first Weekly Shonen Sunday series to publish its 1,000th chapter.
