The Rainamker wasn't his first book .The first one was A time to Kill .Several of his books have been made into films .Most of his books are courtroom type dramas . Legal thrillers ,lawyers, the mob ,corruption,racism and murder . . A couple are about American football .
He was a a lawyer himself but gave up practice to write bestsellers .They're not a bad read but a bit mediocre and samey after a while .
Imo the best one was A Painted House .
