From “Lisey’s Story” Wikipage (the Stephen King book, not the Pablo Larrain/J.J, Abrams miniseries): “The genesis was an incident in June 1999 in which King was hit by a van in Lovell, Maine, and seriously injured; while he was in the hospital, his wife Tabitha decided to redesign his studio. Coming home from the hospital and seeing his books and belongings in boxes, King saw an image of what his studio would look like after his death.”
