Winking at the Brim (Mrs. Bradley Series 48)
Gladys MitchellSally is quite grateful for the freedom her vehicle offers, and between Angela's gossip and her own observations concludes that some dalliances are taking place. The tranquil loch is also cause for close attention: first Sally, then the twins, briefly encounter the fleeting lake creature. Their news is overshadowed by the discovery of Angela Barton's wet body in an abandoned house, a suicide note nearby, a wound on her throat, and a thermos of poisoned coffee near at hand. But if the woman tried to kill herself, reasons Sally, why was the note still dry if she attempted first to drown herself in the loch? And why is there no residue of poison in the thermos' cup?
For answers, Sally consults her grandmother, Dame Beatrice, who has an impressive track record for just this sort of problem. Together, Sally, Dame Beatrice, and secretary Laura Gavin interview and investigate until they find a solution, and one which calls upon a final appearance of the Loch Tannasg creature.
