The stories of Chiara Poggi and Meredith Kercher are two stories and two enquiries that in many ways mirror each other, intersecting in a labyrinth of mirrors into which the profiler and forensic criminologist Roberta Bruzzone will enter. She returns to the Colosseo Theatre after a sold-out performance on 10 October to shed light on two of the blackest episodes in Italian history. Two judicial cases that have left behind a trail of doubts, which it is now time to address in no uncertain terms.
