Detective Comics #351

In "The Cluemaster's Topsy-Turvy Crimes!", Batman and Robin face a puzzling new foe whose crimes twist logic and defy expectation, all while Aunt Harriet stumbles upon the hidden entrance to the Batcave. Meanwhile, the Elongated Man’s long-lost costume goes missing just as he plans to donate it to the Central City Flash Museum. Written by Gardner Fox and brought to life with dynamic art by Carmine Infantino, inks by Sid Greene, and lettering by Joe Letterese, this 1966 issue delivers a clever, offbeat mystery with a touch of whimsy. The cover, penciled by Infantino and inked by Murphy Anderson, captures the chaotic flair of the story’s central riddle.
