The Borrowed Man by Gene Wolfe
It’s set in a future where libraries contain AI simulations of famous authors, and the story begins when the femme fatale goes to check out an AI of an old mystery novel author to help her solve the murder of her rich eccentric father. Fun genre-bending story.
Supposedly there is going to be a posthumously published sequel to The Borrowed Man, “Interlibrary Loan.” Wolfe is definitely one of my favorites, very challenging but rewarding.
