Isobella initiated a mind transfer spell that allowed the criminal Terrence Malson to enter the mind of a small boy named Jeff. When Jeff was older, Isobella told Jeff of what she had done to him and Jeff used one of Isobella's spells to erase her memory. Isobella then assumed the identity of "Mrs Havelstack" and worked in a cafe. (PROSE: Running Out of Time)
