John Grisham's nonfiction work, The Innocent Man: Murder and Injustice in a Small Town,topped the nonfiction list at both Walmart.com and Target last week. At Walmart, Innocent Man beat out Mitch Albom's For One More Day, while Lemony Snicket's A Series of Unfortunate Events #13: The End, was second at Target. Innocent Man has not yet hit the bestseller list at AMS, where the nonfiction bestsellers were led by Barack Obama's Audacity of Hope. In fiction Stuart Woods's Short Straw held on to #1, while What Came Before He Shot Her by Elizabeth George debuted in the second slot.
