While the rest of the country sleeps, Jake Robinson is up every night with bloodshot and baggy eyes, desperately trying to piece together evidence in America's greatest murder mystery. His friends and family call him deranged, but he knows he is right on the brink of uncovering the identity of the dreaded serial killer whom the press calls "Caligula." His only ally in unraveling the mystery is his idol and mentor, Morgan McCready. Morgan is a private investigator who is down on his luck after an intense disagreement with the Chief of Police left him ostracized and badgeless. Jake and Morgan know that there is something more disturbing and treacherous than a single lone killer on the loose. A bizarre coalition of individuals from a variety of backgrounds all share a vested interest in making sure Caligula is never unmasked. How deep does the coverup go and will Jake and Morgan live to tell the tale?
