This fast-paced adventure story is about two young boys who are crazy about dirt-bike riding. They live in a small Northern Ontario town where there are many places to ride in safety — such as the “slimes,” which is a huge mud flat, and the woods with trails that lead to the abandoned ruins of old gold mines. One spring, they discover a newly built cabin with the symbol of a hangman painted on the door and immediately plunge into a terrifying whirlwind adventure involving a gang of thieves and drug smugglers, a kidnapping, and the Mounties.
