It took a daily routine for Haleh Esfandiari to stay level-headed during her 105-day stint in Iran's notorious Evin prison. The Iranian-American scholar paced her room for 3 to 4 hours a day, read, and wrote a book in her head to ward off depression. She was treated respectfully, but "a prison is a prison," she said upon returning to the US.
Esfandiari, 67, was detained at the end of a family visit in December and not released until last week. She attributes Tehran's interest to her job with a Washington think tank. "There is a concern among certain elements that the United States has planned some sort of Velvet Revolution in Iran," she told CNN.
