Baltimore City is a powder keg. Its last few years have seen protests, riots, and too many murders. Its citizens don't trust the police, the police don't trust the State's Attorney's Office, and the State's Attorney wants to put as many cops in jail as she can, regardless of their guilt or innocence. The city is only a sin or two away from going straight to Hell.

In the middle of all this is Matthew Grace. A former crime scene technician turned private eye, Grace is now a forensic investigator for the State's Attorney's Office. It's supposed to be an easy job - working Monday to Friday, reading reports, reviewing crime scene photos, and requesting analyses and comparisons from the BPD Crime Lab.

But nothing is easy in Baltimore, and soon Grace finds himself involved in cases that threaten the very heart of the city he loves. Supported by his wife and aided by a cyber pirate, a judge who collects human skulls, and the most honest cop in the city, Grace must solve the crimes and find the sinners if anyone is to have a chance for redemption.
