Grey Granite takes the story of Chris Guthrie further. She moves to the fictional city of Duncairn, which was earlier called "Dundon" in
Cloud Howe; Gibbon points out in the introduction that Dundon/Duncairn is based neither on
Aberdeen nor on
Dundee (as some reviewers had surmised) but is "merely the city which the inhabitants of The Mearns (not foreseeing my requirements in completing my trilogy) have hitherto failed to build". An important character is her son by her first marriage, Ewan Tavendale, Jr., who becomes a left-wing political activist. ==Adaptations==
