'The perfect read for those who enjoy the bygoneworld charm of Nancy Mitford, Evelyn Waugh and Agatha Christie.' The Lady

Scotland, 1932. Aristocratic private investigator Dandy Gilver strikes again with her witty sidekick Alec Osbourne to solve sinister goings on at a convent on a bleak Lanarkshire moor. The convent was set alight following a mass breakout at a neighbouring psychiatric hospital on Christmas Eve, resulting in the death of the mother superior. Most patients were returned safely but a few are still at large. . . As Dandy interviews each nun in turn she senses a stranger is still lurking in the corridors at night - could they be the same person who left blood-red footprints in the sacristy? One of Catriona McPherson's creepiest - and funniest - mysteries yet.
