Suzie Costello's mother
From Tardis Wiki, the free Doctor Who reference
Mrs Costello was the mother of Suzie Costello. She used to sing Soley, Soley by Middle of the Road to Suzie when she was a child. (TV: They Keep Killing Suzie) Suzie stated that although her father had wanted the Costellos to be the perfect British family, each of them ended up "messed up" in some way. (AUDIO: Sync)
