In By the Skin of His Teeth, 17-year-old Ted MacIntosh, whom author Ann Walsh showcased earlier in Moses, Me and Murder and The Doctor's Apprentice, befriends a young Chinese boy despite the intense prejudice seething in the frontier town. Ted suffers intimidation and violence at the hands of the cruel, arrogant Tremblay and his cronies, but with courage and conviction the young man stands up for what he believes and defends his Chinese friend.
