The Mountain Bike Mystery

When eleven year old Tony falls sick with chicken pox he spends much of his time in the bedroom that he shares with his older brother, Jack, looking out of the bedroom window through his fathers binoculars. When Jack was sick he had observed the movements of two shady looking men who appeared to be exchanging bikes, one leaving a bike hidden in the ditch at the front of the house and the other collecting it later. When the second man, Number Two, fails to collect a bike left in the ditch the boys decide to hide it in their meeting house, a shed at the bottom of the garden, and examine it the next day. But there never seems to be an opportunity to look at the bike and tell Mum and Dad what is going on. Eventually they tell their story and their suspicions to Dad who contacts the local RCMP. The boys are drawn into a mysterious web and finally help the RCMP capture a gang of drug smugglers.
