The writer is Kongkiat Khomsiri, one of the "Ronin Team" credited with directing the 2005 Thai horror film Art of the Devil 2.
Set in 1934 Siam, the story involves a young pregnant woman named Nualjan who's searching for her missing husband.
The overgrown property is managed by the stern caretaker Somchit and inhabited by a number of other people, including another young woman, Choy, who becomes Nualjin's friend, as well as an old woman, a little girl and a man who is seen at the back of the property, digging a hole.
Thai pop culture influences come from illustrator Hem Vejakorn, who wrote a series of 10-satang graphic novel ghost stories in the 1930s and '40s.
The reference was so striking that the Barom Khru Foundation, which claims to supervise Hem's works, issued a statement warning Five Star Production to not violate the copyright of Hem's work.
