The Nelson family is busy on the farm, and Jason and Andy are busy solving new mysteries. Who has been trespassing on their land? Will a hidden camera tell them the answer? Mom and Cathy have a mystery of their own to solve, caused by Dad and the boys. And who is that old man at the party, the one who says he is 85, but is really much younger? This volume in the Farm Mystery Series is as entertaining and strengthening to Christian family values as the rest.
