Maggie O’Farrell’s “Hamnet,” one of last year’s most widely acclaimed novels, imagines the life of William Shakespeare, his wife, Anne (or Agnes) Hathaway, and the couple’s son Hamnet, who died at 11 years old in 1596.

On this week’s podcast, O’Farrell says she always planned for the novel to have the ensemble cast it does, but that her deepest inspiration was to capture a sense of the young boy at its center.

“The engine behind the book for me was always the fact that I think Hamnet has been overlooked and underwritten by history,” she says. “I think he’s been consigned to a literary footnote. And I believe, quite strongly, that without him — without his tragically short life — we wouldn’t have the play ‘Hamlet.’ We probably wouldn’t have ‘Twelfth Night.’ As an audience, we are enormously in debt to him.”

On a summer’s day in 1596, a young girl in Stratford-upon-Avon takes to her bed with a fever. Her twin brother, Hamnet, searches everywhere for help. Why is nobody at home?

Their mother, Agnes, is over a mile away, in the garden where she grows medicinal herbs. Their father is working in London. Neither parent knows that one of the children will not survive the week.

Hamnet is a novel inspired by the son of a famous playwright. It is a story of the bond between twins, and of a marriage pushed to the brink by grief. It is also the story of a kestrel and its mistress; flea that boards a ship in Alexandria; and a glovemaker’s son who flouts convention in pursuit of the woman he loves. Above all, it is a tender and unforgettable reimagining of a boy whose life has been all but forgotten, but whose name was given to one of the most celebrated plays ever written.
