Margaret returns one afternoon from tennis to discover that Lewis, her husband, has committed suicide by taking an overdose of pain medication. Lewis had been bedridden from amyotrophic lateral sclerosis (ALS). They had thoroughly discussed his plan to kill himself before he was unable to do so, but Margaret is surprised when it happens because she expected Lewis to leave her a message. There is none.

As Margaret prepares for her husband’s cremation, she recalls the circumstances under which he left his teaching job--not because of the ALS, but because he used to teach human evolution in his high school biology class, without giving "equal weight" to creationism.

Because this upset many of his students’ parents and local clergy, the principal several times suggested that Lewis might at least give a nod to creationism. However, Lewis, an outspoken opponent of religion, was insulted by this proposal and quit his job.

The undertaker encourages Margaret to hold a wake--to comfort her and their many friends--but she insists that Lewis wanted no wake and no service. The next day the undertaker brings her Lewis’ ashes; she goes out into the country at night and disperses them.
