When the police officers visit the alpaca farm, the farmer does a check of all her white alpacas. The first five she counts are all named after members of the UK boy band, Take That; while the second set are all named after members of the UK boy band, One Direction. She identifies the missing alpaca as Louis.
This is brought to us largely by the same behind-the-scenes crew that made the previous Harlan Coben Netflix series, Safe (2018), two years previously.
The series was filmed in and around Manchester and Stockport in the northern part of England.
