Biff Norris and Chip Edwards, high school friends, find themselves involved in thrilling mysteries and adventures in this exciting series of stories written for boys and girls up to sixteen years of age. Biff fits his nickname, being big and strong, adding a lot of power to the line of Henderson High's football team. Chip, on the other hand, is small and slender, making up for his lack of size by his agility and speed. Together they make an unusual pair. Both are Christians, and because of their faith in Christ, they find opportunities to witness for their Lord under unusual circumstances.
