1. The mystery Hercule Poirot didn't solve, the book Henry Kissinger didn't want to publish and the "Indiana Jones of Manhattan"
Aris Chatzistefanou meets him in the introductory episode of the series, trying to find out all the things those so high-profile people didn't want us to know. The further his investigation goes, the more he comes across the name of Matthew Bogdanos. He is the former colonel of Greek descent who served in Iraq and Korea, and for some years now has been working for the New York City District Attorney's office. Everybody calls him the "Indiana Jones of Manhattan."
