In March of 1926, Daisy Dalrymple Fletcher & her friend Lucy head off for several days at stately home reputed to have the best grotto in the country. Working on a book of architectural follies they plan to research & photograph it. Leaving her husband & young twins behind, Daisy is expecting a productive weekend at Appsworth Hall, with the only potential difficulty being keeping Lucy from offending the current owner, a manufacturer of plumbing products. Alas, it`s not to be quite so simple. At the home, they find themselves faced with a curious assortment of people including the abominable, tactless Lord Rydal, who is rumored to be having an affair with one of the guests while at the same time in ardent & artless pursuit of the hand in marriage of another. When the grotto explodes with Lord Rydal in it, it`s not a question of who would do it
- as most who`ve met him would be sorely tempted
- but who actually did do it.
