In 2007, Iranian-American scholar Haleh Esfandiari left the U.S. on an annual visit to her mother in Iran. But when she got to the country, she was promptly arrested and charged with treason. She tells us how she was kept in solitary confinement for more than 100 days and subjected to grueling interrogations. This is all in her new memoir, "My Prison, My Home: One Woman's Story of Captivity in Iran".
