Aunt Bessie assumes that she'll have the beach all to herself on a cold, wet, and windy March morning just after sunrise, then she stumbles (almost literally) over a dead body. Aunt Bessie assumes that the dead man died of natural causes, then the police find the knife in his chest. Try as she might, Bessie just can't find anything to like about the young widow that she provides tea and sympathy to in the immediate aftermath of finding the body. There isn't much to like about the rest of the victim's family either.
Aunt Bessie is somewhere past 60 and old enough to ignore the rude woman that does her best to ruin the first session of the beginning Manx language class they are both taking. Moirrey's sudden death is harder to ignore. Aunt Bessie believes that Moirrey's death was the result of the heart condition that Moirrey always complained about. The police investigation, however, suggests that someone switched some of the dead woman's essential medications for something far more deadly.
