The Detective is Already Dead Novel

Kimizuka Kimihiko, an ordinary high school student prone to chaos, becomes entangled with mysterious operatives who assign him custody of cryptic attaché cases. His unremarkable life shifts entirely when he meets the captivating detective Siesta aboard a commandeered aircraft, transforming him into her indispensable partner.

Their collaboration flourishes amid witty banter and perpetual financial hardship—[You eliminate the swarm; I'll contain the threat.] [Stop volunteering me as acceptable losses.]—as they navigate impossible circumstances across continents. Deserts yield to jungles, jungles to mountains, mountains to vast oceans as the resourceful detective and her devoted assistant tackle mysteries that push human limits. Casino windfalls grant fleeting luxury at resort hotels, only to vanish by dawn.

She was everything. Then she wasn't.

One year has passed since Siesta's death. Kimizuka remains the sole survivor of their extraordinary partnership, bearing her legacy forward through shadow and danger. Bound by her unfinished wishes and memories that define him, he carries on their work. The detective may be gone, but this mystery-laden adventure continues—unfinished and unrelenting.
