About The Book

A wildly entertaining collection of interconnected stories filled with monsters, myth, and personal mysteries – blending speculative and crime fiction – that reflects our fractured yet shared global reality in which borders blur, consequences ripple, and no one and no story exists in isolation.

Each story follows a distinct agent of the Speculative Detective Agency as they confront cases that defy conventional logic: haunted environments that resist documentation; a Bloody Mary sighting at an elementary school; half a demon terrorizing a neighborhood; an office staffed entirely by functional zombies; and a deeply personal mystery involving a husband who has inexplicably become the moon. Together, these stories create a mosaic of strange investigations grounded in emotional stakes, wit, and sharp storytelling. The anthology boasts 16 stories blending classic investigative elements with science fiction, fantasy, and horror.

Contributors include Scott Adlerberg, Frederick Aldama, Heather E. Ash, Megan Chee, Victor De Anda, Alex Grecian, Alex Hernandez, Monique Laban, Lincoln Michel, Richie Narvaez, Stephanie Nina Pitsirilos, Nadia Amina Rabbani, Karlo Yeager Rodriguez, Lekha Sen, Amber Sparks, and Martin Willis.
