The Detective Is Already Dead (Japanese: ????????????, Hepburn: Tantei wa M?, Shinde Iru., Spanish title: La detective está muerta[a]) is a Japanese light novel series written by Nigoj? and illustrated by Umib?zu.

Ever since he was a child, Kimihiko Kimizuka has attracted trouble. According to him, he was born with a condition that naturally attracts him to troublesome situations, such as being forced to join a flash mob while taking a leisurely walk, accidentally stumbling across an underworld transaction between drug dealers, and being at the site of crime scenes often enough to sometimes be considered a suspect.
One particular day in his third year of junior high, he was kidnapped and forced to carry a suitcase onto an international flight; on that flight, he met Siesta, a woman who proclaims herself to be a "legendary detective". Forcefully made into her sidekick, Kimihiko helped her stop the plane from being hijacked, but not before Kimihiko discovered the existence of underworld organizations. After being constantly pestered, Kimihiko agrees to be Siesta's sidekick and for three years, they worked together, finding and solving an innumerable number of cases.
Now in his last year of senior high, Kimihiko is once again confronted by the ghosts of the past as he tries to solve new cases that fall into his lap. He is extremely bothered by the fact that he is called a detective; after all, the detective is already dead.
