On April 4, 1968, James Earl Ray shot and killed Martin Luther King Jr. in Memphis, Tenn. Though he died a violent death, King led a movement of nonviolence to draw national attention to the evils of racism. Many books have been written about the movement, King, and his assassination, but none are as thoroughly researched and detailed, day by day, even minute by minute, as this excellent account by accomplished investigative author Hampton Sides.
