The film stars Ian McKellen as Sherlock Holmes, Laura Linney as his housekeeper Mrs. Munro and Milo Parker as her son Roger.

Years of Grace Years of Grace is a 1930 novel by Margaret Ayer Barnes. It won the Pulitzer Prize for the Novel in 1931. Despite this, it is not her most well-known work; that honor belongs to "Dishonored Lady", a play she co-wrote with Edward Sheldon, which was adapted twice into film (first as "Letty Lynton" and later with its actual title).
