In the middle of The Empty Hearse, the first episode of season 3 of Sherlock, after a couple of trivial clients pass before our eyes, Sherlock bundles an elderly couple out of the door. He admits that they are his parents. In fact they are his parents. That is, they are Benedict Cumberbatch’s parents, Timothy Carlton and the gorgeous Wanda Ventham, who I have lusted after since 1972 when I saw her in The Lotus Eaters. After a lead role like that I would have expected her to have had a more glorious career than she did. Maybe she was a bit too overwhelming. As it is she looks to have been consistently busy until 2014, with Sherlock and an episode of Holby City. Maybe at the age of 80 she has decided to slow down and watch from the sidelines.
