Leave it to a former Jeopardy! champ to come up with the best analysis yet of last week's finale of The Sopranos. In Prisoner of Trebekistan: A Decade in Jeopardy! ($17), Bob Harris, who won the limit of five games in a row in 1998, tells the story of his long run on the quiz show, and gives tips on strategy. More important than the specifics, however, are Harris' heartfelt recollections of friendships he made with other top competitors, and what the experience taught him about the larger game of life.
