Wanted! Sammy's Super T-Shirt

Sammy had wanted his T-shirt back ever since its mysterious disappearance. It was his super 'You too can be a human dynamo' T-shirt and it seemed to bring him luck. But there are other parties after Sammy's Super T-shirt - parties who know about the shirt's real powers - Angus Dromgoole MacNaught, a man who will stop at nothing, and his boss, 'Control', at the top secret government agency. No sooner do Sammy and his friend and trainer, Marvin, find the T-shirt again, than they become involved in an extraordinary series of adventures to keep it in their hands.
