44 Sabotage Mystery Trilogy 03: Sabotage Surrender

It's time for the final ceremony of the River Heights Celebration, where four candiates are going for the Mahoney Scholarhip. All four are equally qualified--and equally worthy suspects behind the strange occurances that have been happening at the carnival. Arson, theft and threatening notes all combine to provide a stunning conclusion to the Sabotage Mystery Trilogy. Can Nancy finally figure out the saboteur--before it's too late?
