Robert B. Parker’s Cheap Shot by Ace Atkins is the newest Spenser novel and the third written by Ace Atkins since the estate of Robert B. Parker selected him to continue the adventures of the iconic Boston private detective follow the death of Robert B. Parker in January 2010. The bestselling series has been around since 1974, making Cheap Shot a kind of 40thAnniversary celebration of one of the most enduring characters in the annals of American crime fiction. The book breaks onto The New York Times bestseller list this week, hitting #13 on the hardcover fiction bestseller list. image Atkins began his national tour in Boston, appropriately enough, doing a signing at the Harvard Coop and conducted interviews with the National Public Radio show Only a Game as well as the Jordan Rich radio program on WBZ-AM. He then continued on to St. Louis, where he had a large crowd at the St. Louis County Library, and New York City, where he conducted a radio satellite tour and gave a talk at the Mysterious Bookshop. Other tour stops include Scottsdale, Austin, Houston, Tampa and Memphis, with multiple television and radio interviews arranged along the way. Atkins will hit the road again in late July for his new Quinn Colson novel, The Forsaken (Putnam, 7/24)
