A late-night emergency call from a vehicle in motion reached the police in Carinthia: "Eisner, BKA Vienna, service number 318-12-58. I require assistance!" Shortly thereafter, Lieutenant Colonel Moritz Eisner was discovered seriously wounded, slumped and unresponsive behind the wheel of his car in a quarry, the victim of a gunshot wound to the head. He awoke in the intensive care unit with no recollection of the preceding events. The trauma had triggered retrograde amnesia, a complete erasure of the experience itself, a grim consequence of the bullet's path.
