The Murder of Busy Lizzie (Mrs. Bradley Series 46)
Gladys MitchellMarius does make the acquaintance of Eliza's business partner, a dour woman named Miss Crimp, who promptly annoys her guest by situating Marius at the hotel while booking his offspring into a separate chalet. An infestation of ornithologists to the island proves the last straw, but before the Lovelaines can make an exit, a birdwatcher spots the body of a woman being tossed against the rocks by a turbulent sea. Identification shows that the unfortunate woman is Eliza Dashliegh. Marius, who had hoped to reconcile with his sister partly to bolster any potential inheritance she might leave, becomes a suspect in the suspicious death, as does the money-minded Miss Crimp and Lizzie's illegitimate son, an island farmer named Ransome Lovelaine.
Sebastian and Margaret find that the family headstones in the churchyard have been defaced in a curious manner, and unsettling actions and signs point to the presence of witchcraft on Great Skua. Dame Beatrice keeps an eye on events, but she and Laura have come to the island on their own mission. Dead pigs, locked lighthouses, midnight rituals and pirates' caves
