Nineteen year old Gwendolyn lives with her Grand-mama in Preston, a small village north of Brighton. She attended the same school as Emily Pengellon in Hove, and the two became firm friends.

Gwendolyn's father, Cecil, Earl of Carlton, remains on Empire business in India. Gwen lived in India until her teens. Adelaide Barclay, Gwen's Grand-mama, was most insistent with Cecil that "the Raj is not a place for an impressionable young girl", and so Gwen was shipped back to Sussex.

She's a very good shot, having hunted on the estate in Rajastan with Ranjeet, Cecil's local fixer and right hand man. Gwendolyn's mother died giving birth to her. Her older brother, Arthur, is in the army.
