Ponas Holmsas / Mr. Holmes (2015)

The story is actually set in 1947, following a long-retired Holmes living in a Sussex village with his housekeeper and rising detective son. But then he finds himself haunted by an unsolved 50-year old case. Holmes memory isnt what it used to be, so he only remembers fragments of the case: a confrontation with an angry husband, a secret bond with his beautiful but unstable wife.
