Olga Seminoff

In the novel Hallowe'en Party, Olga Seminoff was an au pair from Herzegovina. She worked for Mrs Llewellyn-Smythe at Quarry House in Woodleigh Common. When her employer died some years before the events in the book, a codicil to her will came to light which left everything to Olga. This document was however clumsily made and obviously a fake. Mrs Llewellyn-Smythe's solicitors wanted to question her but she disappeared from the scene and was not heard of again. This also led to speculation that Olga might have poisoned her mistress although the prevailing opinion was that she had died of natural causes.
