What happens when one California community has a disturbing spike in homicides? It catapults cops into a deadly game of murder. Frozen human body parts hideously displayed at the crime scenes offers a horrifying interpretation that only a sadistic serial killer could design—and execute.

On the hunt for a complex serial killer, vigilante detective Emily Stone must face her most daring case yet. Stone’s proven top-notch profiling skills and forensic expertise may not be enough this time.

Young and ambitious, Detective Danny Starr, catches the homicide cases and discovers that it will test everything he knows about police work and the criminal mind. Can he handle these escalating cases or will the police department have to call in reinforcements—the FBI.

Emily Stone’s covert team pushes with extreme urgency to unravel the grisly clues while keeping their identities hidden from the police. With one last-ditch effort, Stone dangles someone she loves as bait to draw out the killer. She then forces the killer out of their comfort zone with her partner Rick Lopez, and with help from a longtime friend Jordan Smith. A revelation of the serial killer’s identity leaves the team with volatile emotions that could destroy them.

The killer continues to taunt and expertly manipulate the police, as well as Stone’s team, and as they run out of time—they leave behind everyone and everything—in Dead Cold.  $0.99 on Kindle.

Detectives from the Yonkers Police Department in New York find the victim of an apparent heart attack with the hair on the right side of his head shaved off. Although odd and out of place, the haircut doesn’t appear to be tied to the man’s death and the detectives put the case to rest. Days later, however, they learn that the man with the unconventional haircut may have been the victim of arsenic poisoning, and set out to investigate. Before they get very far, a witness goes missing and another dead man surfaces with the same hairdo. Eventually, the detectives uncover a connection to a long-forgotten tragedy and, under the direction of their supervisor—Detective Sergeant Hamilcar “Ham” Hitchcock—work tirelessly to connect the dots and identify the killer or killers involved. In the end, they discover, much to their dismay, that they’re not immune to tragedy themselves. $2.99 on Kindle.
