The Witching Hour by Catriona McPherson
A perfect mystery thriller for long evenings! As war looms, Lady Dandy Gilver wants to protect those she love. But a midnight call puts her oldest friend, Daisy, at the centre of a murder case.
As rumours spread of a blood-stained stone, unanswered questions lead Dandy and fellow sleuth Alec Osbourne to wonder: is Daisy really innocent, or are they chasing the wrong clues?
