Premiered on Singapore's National Day on 9 August 2021, and subsequently showed on consecutive Mondays.
The case of the British girl Mariam and whatever happened after her aunt Emma tried to claim her back may or may not have echoes of an actual case which used to take place in post-war Singapore. Maria Hertogh was an Indonesian-born Dutch teenager who was to be in the middle of a custody battle in Singapore in December 1950 between her natural parents claiming her back after the war and her adopted Indonesian mother. Much like the British girl Mariam in the series is not her actual name (as her aunt said that it is Margaret Barron), the teenage Maria was called Nadra by her adopted Indonesian mother Aminah, who is a family friend of the Hertoghs. The Hertoghs did survive the war and tried to claim their daughter back, but this led to a custody battle which came to take place in Singapore. In the intervening years Maria had become a Muslim and her age (14) before the custody battle meant that she was allowed to be married (which she did) under Muslim law, which came to be contested in the courts, and was to be in favour of the Hertoghs. Along with the press coverage at the time, it eventually got out of hand and descended into a riot after the court ruling. Maria and her biological mother would soon leave Singapore for the Netherlands and been there ever since, even if since then Maria would come to have an unhappy marriage and came to pass away in 2009 in the Netherlands.
Due to the COVID-19 pandemic, all the scenes were filmed throughout Singapore. And it was also revealed by author Walter Woon, whose novel 'The Devil's Circle' which the series was based on, that Miriam's story was inspired by Maria Hertogh.
