Peter Malone was an investigative reporter. He had published a book that included information about the killing of Abu Jihad, but did not have Gabriel Allon's name.
Gabriel offered to trade information with Malone: Malone's knowledge of what Benjamin Stern was writing about for background information about Wrath of God. Malone told Gabriel about Monsignor Cesare Felici and Monsignor Tomaso Manzini being missing and presumed dead. He added that Alessio Rossi of the of the Rome police was removed from the investigation of the missing priests and he believed that Crux Vera was responsible. Afterward, Eric Lange entered Malone's residence, killed him, and stole his computer.
