This is an older Grisham novel, but one I had not read before. I found myself not wanting to put it down!Adam Hall is a young lawyer in a large firm. Sam Cayhall is his grandfather, on Death Row for a Klan-related killing in the 1960s. Many years later, Sam's appeals have run out -- and Adam offers to represent him pro bono through the offices of the firm.The two get to know each other over a four-week period, and Adam learns many family secrets in the process. Without posting spoilers, suffice it to say that there is much more to the situation than meets the eye.As always, Grisham gives us multi-facted characters and situations. Highly recommended for those who enjoy a legal thriller.
