Mutant City Blues creator Robin D Laws brings you four ready-to-play case files to puzzle and challenge your local Heightened Crimes Investigative Unit.

The Hard Helix: A controversial researcher into mutant powers Sidney Dorris is found murdered the evening before his scheduled announcement of a stunning scientific breakthrough. What was his secret, and who was willing to kill him for it?

The Vanishers: The squad's intervention in a jewelry store robbery leads them into an operation against the new school, mutant-bolstered forces of organized crime.

Super Squad: A sudden death at a mutant-related riot leads the unit into the twisted world of the Super Squad, an elite policing group who work the city's toughest streets-and have, in the process, gotten more than a little dirty.

Cell Division: The detectives confront a homegrown terrorist threat from a previously unknown group of mutant supremacists. Can they uncover the truth behind the Mutant Revolutionary Front - one that remains shrouded even from its own suicidally indoctrinated followers?
