The arrival of a mysterious invitation from Lord Findley to visit his mansion on a reclusive island immediately catches her attention.

On the train, Miranda makes the acquaintance of five other guests — Donald Walker, an American journalist; Lawrence Kane, Esq.

Welcoming the guests are the three members of Lord Findley's staff, who is apparently stranded due to bad weather and will only join them by plane the next day.

As they depart the estate, Miranda expresses her intent to become a more official investigator, and Findley's various children all agree to remain in each other's lives.

[3] Mischa Barton will reprise the role of Miranda Green for two sequels Murder at the Embassy and The Mystery of the Golden Spear, both set for release in 2025.
