Cinnamon Skin (1982) is the twentieth novel in the Travis McGee series by John D. MacDonald.

Like a few other books in the series, McGee ends up traveling to Mexico to solve a crime.

As Meyer and McGee investigate the explosion, they discover her husband, Evan Lawrence, did not die, and instead had a dark and dangerous past.

In the meantime, McGee's relationship with Anne Renzetti, with whom he fell in love in the previous novel Free Fall in Crimson, unravels as she pursues a business opportunity in Hawaii.

Meyer names his new houseboat after Thorstein Veblen.
