With nationwide calls for police reform and defunding, literary giant John Grisham's novel A Time for Mercy is undoubtedly timely, as it explores the ways that violence committed by or against law enforcement officials can complicate the pursuit of justice.

Jake Brigance—the hero of Grisham's 1989 debut, A Time to Kill—is court-appointed to represent 16-year-old Drew Gamble in the shooting death of his mother's boyfriend, deputy sheriff Stu Kofer. There's no question that Drew pulled the trigger, but Jake faces an ethical challenge over whether the shooting was justified. Drew contends that he shot Stu in self-defense after believing Stu had killed his mother. Drew, his younger sister and their mother lived in constant fear of beatings by Stu, who often returned home in a drunken stupor.

Jake only wants to handle preliminary matters for the Gamble case until a permanent public defender can be appointed. But deep down, he realizes he's the best chance the Gamble family has. With public sentiment and fellow police officers standing behind Stu and his family, Jake's efforts to keep Drew from being tried as an adult and facing possible execution put him at odds with the community.

While there are lulls during some of the legal procedural bits, Grisham's mastery of the courtroom thriller is never in question. As usual, he presents as smooth a read as you'll ever experience. The dialogue is sharp and pointed, layered with genuine emotions that make the characters pop off the pages of this morally complex story.

At the start of bestseller Grisham's disappointing third outing for attorney Jake Brigance (after 2013's Sycamore Row), deputy sheriff Stu Kofer comes home one night in 1990 to the isolated house outside Clanton, Miss., he shares with his lover, Josie. In a drunken rage, Kofer falsely accuses Josie of infidelity, and knocks her unconscious. Kofer falls asleep after a half-hearted attempt to break into the room of Josie's 14-year-old daughter, Kiera, whom he has sexually abused. Josie's 16-year-old son, Drew, believes his unresponsive mother is dead, and fears Kofer will attack Kiera. After dialing 911 to report Josie's murder, Drew takes the sleeping lawman's service weapon and shoots him in the head. A judge taps Brigance to defend Drew after the teenager is charged with intentional homicide. As Brigance prepares his case, he learns a secret that he hopes will bolster his chances in court. The high-profile murder trial that follows, however, doesn't live up to the promise of the book's harrowing opening: the prosecuting attorney proves a weak opponent for Brigance, and the tepid courtroom proceedings fail to engage. This one's for Grisham diehards only. Agent: David Gernert, Gernert Co. (Oct.)
