The Death of Khun Phra.

Set in Suwanthani during the early Rattanakosin era and follows three slaves—Sang Thong, Mai Phlong, and Thong Bai—who work in the household of Khun Phra Bamroekrung. Sang Thong is a charming talker, Mai Phlong is quick-witted but not very bright, and Thong Bai is an inventor whose creations resemble things from 2025. Despite being close friends, they all fall for Jolie, a foreign missionary teaching English to Khun Phra Bamroekrung's children. When the groom is found shot dead at Khun Phra Bamroekrung's wedding, the three are suspected of murder. Faced with overwhelming evidence against them, they must escape and uncover the true killer.
