In March of 1926, Daisy Dalrymple Fletcher and her friend and collaborator Lucy (a.k.a. Lady Gerald) head off for several days at stately Appsworth Hall, reputed to have the best grotto in England. Working on a book of architectural follies, they plan a productive weekend researching and photographing it. Alas, it's not to be quite so simple. When the grotto explodes with the abominable Lord Rydal in it, the question is not who would do it, but who did do it.
