Delia Hartston
From Tatters of the King
Delia Hartston is Alexander Roby's former fiancee. When Dr Bartlett spoke to Roby, Roby initially seemed to think he was talking to Delia.
Grahame Roby expressed a distrust of Delia, suggesting she was in some way involved with the Roby murders.
Her current location is unknown, but Captain George Withers has engaged a private detective to locate her.
