While Jay and Antonio were carrying out the interrogation, a very slight noise distracted Jay and consequently his colleague.

Someone had inserted a key into the keyhole of the back door and very delicately opened the door.

The noise, however minimal, did not escape the two of the Intelligence.

- Is anyone home with you? - Asked the senior detective.

- No, as I told you, I'm alone. - she replied.

Meanwhile Jay had sneaked off trying to find out who had entered.

But that person, having heard that there were strangers, thought it best to run away.

- Stop, Chicago PD,- Halstead said with the gun pointed in front of him.

The woman ran off and got into the car.

Jay chased after her for a while running after her to the gate of the mansion, then he stopped and walked back, not before copying her license plate.

It was a metallic dark gray Mercedes.

He grabbed the radio and ...

- 5021 George, I need you to check this license plate for me.- he said.

Then he joined Antonio who had stayed at home with the woman.

- Okay, we're done for now, - Dawson said. - If you hear Mrs. Alden, tell her we need to talk to her.-

Having said this, they left the villa and got into the car and left to return to the district.

Meanwhile, a little further on, the metallic dark gray Mercedes was parked in a side street a little more hidden than the main road.

A woman was waiting to see the detectives drive out of the gates of the villa.

Shortly after she noticed her and when she was gone she reopened the gate with the remote control and entered.

She was Mrs. Alden, she had managed to avoid meeting the two detectives.

- Nora, what's going on? Two of the police came. - Emily asked.

- Don't worry, little sister, - she replied

- What are you doing? - Mrs. Connor asked

- I have suffered for a long time,- she said, - now it's time.-

Once this was answered, she walked away with a satisfied air.
