On November 13, 2015, Antoine Leiris s wife, Helene Muyal-Leiris, was killed, along with 88 other people at the Bataclan Theater in Paris, when three men armed with guns and suicide bombs opened fire on the unsuspecting crowd at a rock concert. Three days later, Leiris, a young journalist, wrote an open letter addressed directly to his wife s killers, which he published on Facebook. The whole world was in mourning for the victims of the attacks in Paris, but Leiris refused to be cowed or to let his 17-month-old son's life be defined by Helene s murder. He refused to let the killers have their way. For as long as he lives, this little boy will insult you with his happiness and freedom, he wrote of his son. Instantly, that short Facebook post caught fire. It was shared over two hundred thousand times and was reported on by newspapers and television stations all over the world. In his beautiful and heartbreaking defiance of the terrorists who had killed his wife, Leiris became an international hero to everyone searching desperately for a way to deal with the horror of the Paris attacks and the grim shadow cast today by the threat of terrorism.
