The medium, Sarah Pensell, claimed to be in contact with Liza from beyond the grave. At a seance, she recollected a day spent in the park with Murdoch and a necklace with a silver horse pendant on it. Pensell told Murdoch that Liza would not speak through her again. Liza wanted Murdoch to move on with his life ("Elementary, My Dear Murdoch").
Liza was mentioned by Arthur Conan Doyle when he visited Toronto in search of a cure for consumption. Doyle's wife, Louise Hawkins, was suffering from the disease in the same way Liza had ("Belly Speaker").
- Though mentioned and credited only as "Liza" on the television series, Maureen Jennings gives the character's full name as Elizabeth Milner in Except the Dying.
