Two detectives, assisted by their colleague Sophie, are investigating the mysterious rooms they have encountered. They aim to uncover the truth about the rooms and their owner. The detectives begin by examining the first room, but they quickly realize that it's been contaminated with their own fingerprints and hair.
They decide to move on to the corridor, where they believe they may find clues that haven't been touched yet. They notice that the light switches could be a good place to find fingerprints, as they are often touched. After searching, they find a mysterious brown footprint on one of the switches.
The detectives also find a tuft of beige hair, which they believe could be a crucial clue. They decide to send the hair to a forensic laboratory for examination.
The investigation is ongoing, and the detectives plan to continue their search for clues tomorrow. So far, they have discovered that the person who left the footprint has dirty fingers with a brown substance and that the hair found is smooth and soft.
