Christopher Hitchens' Widow On Mourning And 'Mortality'

For 18 months, while undergoing treatment for esophageal cancer, Christopher Hitchens chronicled his year of "living dyingly" in a series of essays for Vanity Fair. Those essays, as well as never-before published notes from Hitchens' final days, are compiled in a new, posthumous book titled, Mortality. Carol Blue, Hitchens' wife of 20 years, wrote the afterward to the book. She talks with NPR's Neal Conan about her husband's final days.
