Persona Non Grata: Quint Adler Thrillers, Book 7 (Unabridged‪)‬

Persona Non Grata is Quint Adler's most tumultuous case yet. A close friend of Quint's is murdered and he agrees to investigate it, not knowing just how depraved the case will become. After discovering a second—and then third—murder, Quint knows he should bow out, but he's too far entrenched to turn back now. It may prove fatal for our beloved Quint.
