On January 18th, just before midnight, an Argentine state prosecutor named Alberto Nisman turned up dead in his apartment. The cause of death was a shot to the head, fired from a .22-calibre pistol that the prosecutor had borrowed from his assistant the day before. Nisman told his assistant that an Argentine spy had warned him that his life was in danger. The two main doors to the apartment were locked, and several bodyguards had been standing watch outside. Analysis of a third passageway, a small nook used to gain access to the apartment’s air-conditioning unit, revealed a footprint and a smudge, but nothing more. The door to the bathroom, where Nisman was found, was locked from the inside. It looked like he had killed himself, but could someone else have made him do it?
