S1·E7 Episode 7

Author and spiritualist Arthur Conan Doyle is in Selfridges for a Sherlock Holmes book signing when he persuades Harry to hold a seance in the store - and the results of the gathering force the retail magnate to have a long-overdue heart-to-heart with Lois. Meanwhile, Agnes is transferred to women's fashion, Doris resolves to help an old friend, Miss Mardle is still agonising over Mr Grove, and Kitty has a secret admirer.
