Elliot Roosevelt writes about his father this time-as Governor of New York, he is ready to attend the Chicago Democratic Convention and accept the nomination for President. But before he does, he needs to enlist the help of his boarding school chum "Blackjack" Endicott to penetrate the criminal underworld to solve a mystery of murder and the mob.
Blackjack Endicott is attempting to find out who is trying to murder Govenor Roosevelt so it will be safe for him to come to Chicago and accept the presidential nomination. Historical references about prohibition, the mob and politics of the era are interesting.
