Copycat Dreams. Dreams and Reality, #20

Marshal Aislinn Cain and the serial crimes tracking unit are sent to New York City to investigate murders identical to murders committed during the 1980s. However, the serial killer responsible for the original murders is dead, killed in a shootout with the NYPD when they cornered him dumping his last victim. This new series of murders though includes details never released. Only the medical examiner's office and investigators working the case knew the killer shoved straight pins in the soles of his victim's feet.
Every murdered woman, dumped in the same location as the original victims, in this new series has, not just the straight pins, but the same brand, pushed into the soles of their feet. The SCTU will need to reinvestigate the original case to ensure the NYPD got the correct man, while investigating this new series and identifying reasons someone would replicate this particular series of murders. During their investigation, they'll meet the nemesis of murdered hero US Marshal Nathan Green.
Can they vindicate Marshal Green's suspicions about his nemesis and solve both series of murders or will they leave NYC questioning if they got the right man too?
