Dies Irae: A Scott Drayco Mystery

Three years ago, Scott Drayco left the FBI after an incident involving his partner, Mark "Sarg" Sargosian. Now a freelance crime consultant, Drayco often helps law enforcement on cases, but he never imagined his estranged former partner would turn up on his doorstep, pleading for Drayco's help. A coed at an elite Washington, D.C., private college has been murdered, and the victim's friend, Sarg's own daughter Tara, might be the next target.

The killer left behind a puzzling music code at the crime scene, and Drayco soon learns he has two things in common with the murdered girl - a music background and synesthesia. The case takes an even stranger turn after a second murder and a second music code, with signs pointing toward a possible ritualistic killer. Then, Drayco himself starts receiving coded messages and finds himself locked in a deadly game with a madman where only one of them may come out alive.
