The Death of Khun Phra (2025)
This story takes place in Suwanthani, a city that existed in the early Rattanakosin era. It follows Sangthong, Maiphlong, and Thongbai, three slaves in the house of Khun Phra Bamroekrung. Sangthong is a handsome sweet-talker skilled at flattery, Maiphlong is dim-witted and quick-handed, and Thongbai is an inventor; every item he makes is strikingly similar to things that have come up in 2025. The three are beloved friends, but they get in each other's way as they all fall for the charming foreign missionary Jolie who's come to teach English to Khun Phra Bamroekrung's children.
When, during the chaos of Khun Phra Bamroekrung's wedding, the groom is found shot dead, the three friends fall under suspicion for his murder. Up against overwhelmingly incrimating evidence, the three have no choice but to make their daring escape and hopefully discover the true killer.
