Fans of the other Alcatraz books will enjoy spending time with these characters again.  In this installment Moose’s dad has received a promotion, and rumors indicate the cons could be out to get him.  When Moose and his sister are left alone one evening and fire breaks out in their apartment, Moose is left struggling with the guilt that his negligence could have contributed, the worry that someone might have set it on purpose (and the puzzle of trying to figure out who), and the neighbors’ accusations against his sister.  The kids on the island band together to try to solve the mystery, and end up uncovering more than one island conspiracy.  The way things are tied up a little too neatly and too abruptly at the end, without enough clue-dropping along the way, keeps it from getting a higher rating.
