On a visit to the ruins of Madderstone Abbey, Penelope Lambe suffers a bad fall and before she slips into unconscious, manages to say 'I saw her, it was her'. Some take these words to mean that Penelope saw the Grey Nun, the ghost reputed to haunt the abbey, but Miss Dido Kent is determined to find the real cause.
Book #3 in Anna Dean's Dido Kent series.
