Jean-Baptiste Grenouille came into the world unwanted, expected to die, yet born with an unnerving sense of smell that created alienation as well as talent. Of all the smells around him, Grenouille is beckoned to the scent of a woman's soul, and spends the rest of his life attempting to smell her essence again by becoming a perfumer, and creating the essence of an innocence lost.

In a room with no windows on the eastern coast of Africa, an Englishman, James Moore, is held captive by jihadist fighters. Thousands of miles away on the Greenland Sea, Danielle Flinders prepares to dive in a submersive to the ocean floor. In their confines they are drawn back to the Christmas of the previous year, where a chance encounter on a beach in France led to an intense and enduring romance.
