Which C.S. Lewis work was published posthumously in 1964 as a memoir of grief?

C.S. Lewis’s A Grief Observed was published posthumously in 1964 as a memoir of grief.

The book records Lewis’s experience after the death of his wife, Joy Davidman, from cancer in 1960. It was first published under the pseudonym N.W. Clerk, partly because Lewis wanted readers to encounter the writing without immediately treating it as an authorial statement about his public identity.

A Grief Observed is structured as a series of reflections rather than a conventional narrative. Lewis confronts bereavement, anger, doubt, memory, and the difficulty of reconciling suffering with religious belief.

Joy Davidman and Lewis had married in 1956 in a civil ceremony and later received a Christian marriage ceremony. Lewis died in 1963, and the book appeared the following year under his real name.
