Thank you for all the love on my last story.

Previously in recovery -

Jay hugged his girlfriend on the couch but as he got comfy his phone started buzzing, "hello?"

"Is this Jay Halstead?"

"Yes Who's this?"

"I think you should know who this is!"

Jay went to speak as the phone was hung up, "Who was that?"

"I have no idea, they just hung up"

"Well that was weird"

"Yeah I know, I'll check it out at work"

It has been a month and Jay was checking something out at the district when his phone rung, "hello?"

"It's Erin. Where are you?"

"I'm at the district, what's up?"

"I was out with Harper for a walk and I just got back to the apartment but the door is wide open. Did you shut it?"

"Of course I shut it, I'm on my way. Dont go in the apartment Erin just wait outside"

Jay quickly knocked on Voights door, "I gotta go somethings happened at the apartment"

"Okay you still need to talk to me?"

"Yeah this might be related but I'll get back to you"

"Okay"

Jay's POV

I quickly got to the apartment and saw Erin stood outside with Harper in her Stroller, "You Okay?"

"Yeah I came straight outside with her"

"I'll check it out" I pulled out my gun and I walked down the hallway toward the open door. As I stepped foot in the apartment I noticed it was tidy and nothing looked out of place. "CHICAGO PD!" I shouted through the apartment by there was no noise nothing.

I checked each room but the apartment was empty but nothing had been stolen either. I looked down the hall and saw Erin coming in,

"It's okay no ones here" I shouted down to her as she carried on walking up.

"Anything gone?"

"Nothing It's doesn't even look like anyone was here but I definitely locked the door"

Erin picked Harper up and held her in her arms, "Is this to do with the phone calls?"

"I don't know I still need to talk to Voight"

"Please Jay is something is going on our daughter lives here and I need to know if it is safe"

"I know that Erin... look ill talk to Voight now but I want you to come with me for now just until we find out what's happened"

"Yeah Okay" Erin put Harper back down and spun her stroller around and walked out the door.

Nobody's POV

Erin and Jay got to the bullpen and Erin was greeted by the team straight away as they all wanted to see Harper, "I'll talk to Voight" Jay kissed Erin as he walked away.

Jay went to his desk and pulled a folder out before knocking on the door and walking in, "Everything alright?" Voight asked

"I need to talk to you about something"

"Yeah Okay sit down" jay shut the door behind him and sat down.

Jay opened the folder and pulled everything out, "so the night Harper was born I had a phone call and it was guy I don't know and all he said was 'you should know who I am' before putting the phone down."

"Okay so what's with the file"

"Right so I didn't think anything of it but then it happened it again but there was no one there and the phone just hung up. I've had these phone calls at least four times now and then I went to the apartment the door was wide open which I locked by nothing was taken or out of place"

"Okay did you trace the phones"

"Yeah Mouse did it, all disposable phones"

"What are you thinking this could be?"

"I don't know. The guy who shot me is in county jail and im not worried about me, I'm worried about my family."

"So is this a stalker or something from your past"

"I dont know but if they are breaking into my home then I need to find out"

"And we will don't worry"

"Thanks Voight. I'm gonna get the girls home but I'll be back at work tomorrow"

"See you tomorrow and I'll look into this" voight took the file from Jay as he left.

Jay walked out into the bullpen and saw Antonio sat with Harper and Erin was talking to Kim, "Erin?"

Erin walked over to Jay and sat on the desk, "what's going on?"

"Voights going on look into it but we will find out what's going on"

Antonio looked up and listened to jay, "What going on bro?"

"Oh some weird phone calls and our apartment door was open when Erin went back earlier. Someone's just messing with us"

"Yeah Voight will figure it out" Antonio said as he got up and passed Harper to Erin.

"Let's go home" Jay said as he grabbed hold of Harper's stroller.

What's gonna happen??
