Mr. Applegate is too excited to explain what he was doing there, so the Hardy boys have to go back and explore the home another day. Upon further exploration they find an unused wing of the home which has recently had locks added to the doors. The police are called who find the locked rooms filled with stolen goods, stolen by the river thieves. While the police thought this resolved the case, the Hardy boys kept an eye on the Purdy house and found a stranger coming to the house, who then runs away after another scream is heard.
