On January 23, 2002, Mariane Pearl's world changed forever. Her husband Daniel, South Asia Bureau Chief for the Wall Street Journal, was researching a story on shoe bomber Richard Reid. The story drew them to Karachi where a go-between had promised access to an elusive source. As Danny left for the meeting, he told Mariane he might be late for dinner. He never returned. In the face of deat, Danny's spirit of defiance and his unflinching belief in the power of journalism led Mariane to write about his disappearance, the intense effort to find him and his eventual murder in her memoir A Mighty Heart: The Brave Life and Death of My Husband Danny Pearl.
