A historical map, an unfinished hand-written letter, and a mysterious picture baffle the duo. What is the purpose of the secret room? And why does Kyle hear strange noises beneath the floorboards during the night? Fast rides in a convertible, being pursued by the police, a homeless friend named Tad, and a house filled with random reptiles add to the excitement of the journey.

Don't miss out on any of the fun.
