The Truth - Salvatore's Revenge: Book 5 of the Caselli Family Series

"When we started solving cases we had only our wits and common sense. We had no 'smartphones' or social footprints to follow. The FBI had a limited database of fingerprints (about two million), but there were no DNA files we could cross-reference. Early cellphone calls could not be traced; very simple, networked computers were limited to whatever had been inputted into them. The internet twenty years ago was not what it is today. We relied on paper files, old memory notes, microfiche, fax machines, and ordinary maps..."
Marquette Caselli, famed private investigator, faces his most difficult (and oldest) case. Set in the summer of 1998, he is without the benefit of modern day tools and technology. He will have to use his intellect to keep his family safe from the most dangerous member of the infamous Ponerello family, Salvatore Ponerello.
