Some flowers bloom in darkness. Some carry secrets that can kill.

When a single black orchid petal arrives in the dead of night, slipped beneath Detective Dujo's office door with no sender and no explanation—only a chilling note—his instincts flare to life. "She is in danger. Find her before the next full moon."

Five days.
No name.
And a ghost from his past.

The petal is more than a warning—it's a signature. A symbol once associated with Dr. Lucian Moreau, a brilliant but twisted figure Dujo thought was long dead. Now, whispers of Moreau resurface, tied to secret experiments, missing people, and a woman whose life may already be hanging by a thread.

With his sharp-witted nephew Bisu at his side and the trail leading to a mysterious florist who deals in danger as much as in flowers, Dujo must confront memories he's buried and enemies he never truly escaped.

Because some mysteries aren't puzzles to be solved.
They're traps waiting to be sprung.
