A Cold, Hard Case by Dan Petrosini
Half of the time, the killer gets away...
and the case goes cold.
Detective Luca knows there are hundreds, if not thousands of killers out there. When he receives a strange call about an unsolved murder, the evil that struck 25 years earlier resurfaces.
A teenage girl brutally murdered. A younger brother who was with her that night. A devastated mother, unable to move on.
