The Defected had been in the making since as early as 2016, when TVB announced its plans for more collaboration projects with Chinese media giants iQIYI and Tencent.^[2] Chu Kang-ki pitched the story to producer So Man-chung at around that same time, who immediately expressed interest in working on the show. For the next two years, Chu and his wife Lau Siu-kwan worked on perfecting the script. The duo drew many inspirations for the story from the Gallant Garden, a public cemetery for civil servants,^[3] specifically the 55 Hong Kong police officers buried at the cemetery. The Gallant Garden is also a setting that appears frequently throughout the show. Chu said the story of The Defected is a homage to 90's era Hong Kong police films and television dramas, in which bravery and honour were central themes.^[3]

Casting began soon after the script for The Defected was completed. Kara Wai was the first choice to play Man Hei-wah, an ambitious and ruthless police official who vies to become the first female commissioner of police.^[3] Benjamin Yuen lost 20 pounds for his role as Sheung Sing.^[4]
