The investigation was going on when the Guard who saw Anna in Thomas's lab as Sophia gave his statement to the police.
The guard's statement
Maybe what I'm going to say will be helpful in this case or not. But I have to tell the police so I wouldn't regret later that I hid something very important in a big criminal's case.
Before one day of Thomas's escape attempt, the unknown lady entered the lab. One female servant confused us by calling that lady her sister. So, we allowed an unknown lady to go.
Due to the investigation going on many gadgets, it's challenging to keep a record of all. So that's why we didn't notice any theft. But then I heard a police officer's statement that servant maker was used on them. And its effect remained on them for around 15-20 minutes.
So I got confused because it's an ordinary toy, and almost everyone knows its effect remains for a short time.
