Daved Baldacci, whose new novel, “True Blue,” is hitting the best-seller lists, and literature professor Lewis Frumkes had a few laughs the other day when Frumkes told him he looked very much like John Grisham. “Hey, you are both lawyers turned mega-thriller-writers, and only a few years apart . . . maybe you are really brothers who were separated at birth,” Frumkes said. Baldacci chuckled and replied that he and Grisham are actually close friends, and that when he mentioned to Grisham that he was looking for property in Charlottesville, Va., John urged him to move near him. What a good brother!
