The basis for the Major Motion Picture Mr. Holmes starring Ian McKellen and Laura Linney and directed by Bill Condon.It is 1947, and the long-retired Sherlock Holmes, now 93, lives in a remote Sussex farmhouse with his housekeeper and her young son. He tends to his bees, writes in his journal, and grapples with the diminishing powers of his mind. But in the twilight of his life, as people continue to look to him for answers, Holmes revisits a case that may provide him with answers of his own to questions he didn’t even know he was asking–about life, about love, and about the limits of the mind’s ability to know. A novel of exceptional grace and literary sensitivity, A Slight Trick of the Mind is a brilliant imagining of our greatest fictional detective and a stunning inquiry into the mysteries of human connection.
