The film, based on the novel “A Slight Trick of the Mind” by Mitch Cullin, was adapted for the screen by Jeffrey Hatcher (The Duchess, Stage Beauty).
It begins in 1947 when an aging Holmes returns from Japan, where, in search of a plant with powerful restorative qualities, he has witnessed the devastation of nuclear warfare. Now in his remote seaside farmhouse Holmes faces the end of his days tending to his bees with only the company of his housekeeper (Laura Linney) and her young son, Roger. Grappling with the diminishing powers of his mind, Holmes comes to rely upon the boy as he revisits an unsolved case which forced him into retirement, and searches for answers to the mysteries of life and love before it’s too late.
The additional cast includes Hattie Morahan, Patrick Kennedy, Hiroyuki Sanada, Roger Allam, Philip Davis, Frances de la Tour and Milo Parker with producers ranging from Anne Carey (The American, Adventureland) of Archer Gray Productions and Academy Award winners Iain Canning and Emile Sherman of See-Saw Films (The King’s Speech, Shame).
