The police would not believe that a ghost was involved in the case, so Lauren could only let them see it for themselves. This way, the evidence would be more direct.
"When the time comes, monitor Susan at all times through the surveillance cameras. If you notice that she really wants to do something to Ruby, you can immediately go in and protect her."
At the moment, the police had no other choice but to agree with Lauren's plan.
After the police went back, they planned to arrange for Ruby's social worker to talk to her.
"Mr. Policeman, we'll implement this plan in two days' time. Ruby is very cautious. It's best not to alert her."
Lauren left the kindergarten early today. She could see that Ruby was already a little suspicious.
If Ruby was taken away immediately, she would likely be suspicious.
The police agreed, and then Lauren went back with Franklin.
