Darriby Hall is famous for entertaining second-tier aristocrats, tales from distant lands and a dead body . . . every now and then.

England, 1926

When an American party of intellectuals, who boast of knowledge of a rare slug species, ask Lady Darriby-Jones to stay at Darriby Hall, she hesitantly agrees.

She is in for a rude awakening when one of them is found dead with a gunshot wound. She thought it would be a matter that might be swept under the carpet until she's identified as a suspect. It leads her to wonder:

Who's the trigger-happy culprit? When did they turn into a slug-slayer? How on earth did they pull off this shocking slug-icide? And . . . Why, oh why, would anyone shoot a slug savant?

With her reputation teetering on the brink of disgrace, Lady Darriby-Jones must reluctantly embrace her inner detective and ask more uncomfortable questions if she is to prove her innocence and find a cunning killer.

Failure to do so will lead to her good name being tarnished and a bumbling police chief dragging her behind bars.
