In the previous Chapter 20,
After their lunch, Robert asks, "What should we do now?"
The 6 men say, "We will patrol around the mansion."
Robert thinks of going back to his room but he is very full. He decided to join them in patrolling.
Robert and the rest don't know what's going on and Adeline didn't tell them anything.
Robert knows in his mind something happened last night and Paul is in the hospital and seems to be in serious condition.
The 6 men didn't have any tools or special weapons with them and they are not afraid of patrolling the mansion.
Robert thinks if he is afraid then he might look timid.
Robert says, "I will join in patrolling with everyone."
The 6 men say, "Okay, we will pair up with you."
Adeline thinks about who is involved in the case.
The time is clicking and running out.
Adeline looked at the food on the table. She gets up and goes to the table sat down and eats.
