1. Come Sail Away With Me

My first Chicago PD fan fic! I am a massive "Linstead" shipper. I've been brain-storming ideas for a Linstead story and this is what I've come up with. I hope that you enjoy it.

DISCLAIMER: I DO NOT OWN ANYTHING OR ANYBODY THAT HAS TO DO WITH CHICAGO PD OR ANY SONGS THAT ARE MENTIONED IN THIS STORY.

Undercover Honeymoon: Who doesn't want to get paid to take a dream vacation? Erin and Jay are going undercover as newlyweds on a luxary liner to catch a thief. How long before business and pleasure collide?

Rated T to M

Jay Halstead sighed as he zipped his suitcase. He wasn't exactly looking forward to his latest assignment. A 7 day cruise may sound like a dream to some, but not to a detective who had always had a mild case of sea sickness.

"So, you planning on telling Lindsay that you're into her?" Adam asked as he sank down onto Jay's couch.

"Ruzek, you're losing it. It's not like that with me and Erin, we're partners. Nothing more...nothing less" Jay pulled the handle up on his rolling suitcase and grabbed his duffel bag as he looked around to make sure he hadn't forgotten anything.

"Whatever you say, Halstead. All I know is I'm going to love seeing your balls gold plated on Voight's desk when you don't keep it in your pants on this assignment" Ruzek laughed as he stood up and helped Jay with his bags.

"Shit" Jay swore and walked back into the bedroom before coming out with a small velvet box.

"What's that?" Ruzek asked pulling a duffel bag over his muscular shoulder.

"It's nothing" Jay said as Adam yanked the box out of his hands.

Adam took the box and opened it and looked at the 2 carat princess cut ring nestled in the box. "What the hell is this?"

Jay sighed and looked at Adam "It's a ring. It's for Erin. If we're going undercover than it needs to be believable"

Adam looked at his friend and then down at the ring before closing the box. "You're going to give your partner a ring like this and tell me it doesn't mean something?"

Jay grabbed the ring back before shoving it in his jacket pocket. "Yes. Nothing is going on between me and Lindsay. Now let's go before we're late and Voight rips us all a new one"

Erin Lindsay stood at the cruise ship terminal waiting on her partner. Dawson and Olinksy were already on board setting their equipment up while Voight was giving the the cruise ship director and captain a run down of what was going on with the undercover work.

Erin looked at her watch and down the terminal to see her partner walking towards her.

"Where ya been Halstead?" Erin asked as sat her duffel bag down and waited for her partner to catch up.

"Sorry, parking is a bitch and trying to get through security is even worse" Jay explained as he finally met up with Erin.

"Well, Voight is pretty pissed at you. You missed the final briefing" Erin explained as she reached into her purse to retrieve her sunglasses.

"Shit. Well, at least I won't have to see him for a week" Jay rolled his eyes and adjusted his bag on his shoulder.

"Nice of you to finally join us, Halstead. I was starting to think I was going to have to do my job AND yours" Hank Voight said quietly but sternly.

"Traffic boss. What can you do?" Jay attempted to joke.

"What can you do? Show up on time Halstead that's what you can do. I don't know how I can trust you to take down a con artist, when I can't even trust you to make it to a boat on time" Voight narrowed his eyes at Jay as he looked around the room at the other passengers before continuing. "This isn't some vacation for the two of you. This. Is. Business. Mike Lane is one of the biggest money laundering con artists of the last 5 years. He's looking to take a big hit on the casino this week. Your job is to take him down. Olinsky and Dawson are already on board setting up. Get on there and get to your room. I'll meet you to video chat tonight with your latest updates"

Jay and Erin nodded and took their envelope that Voight handed to them. They pulled out their boarding passes. Erin couldn't help but feel the pull on her heart at the name "Mrs. Erin Halstead" printed across the top of her boarding pass.

"Suite 234? Fancy Sargent" Jay said looking at his boarding pass and giving a quick glance at Erin before looking at Voight.

"It's not a vacation. But if you're going to play newlyweds than you're going to have to follow the part" Voight looked down at his watch and back at Erin and Jay. "You need to board. Olinsky and Dawson are only a few rooms down from your suite in 226. Keys to both rooms are in the envelopes. Follow your orders and DON'T break the cover"

Jay cleared his throat before looking at Erin "Speaking of cover" and reached into his pocket to pull out the ring "I figure if you're going to be Mrs. Halstead this week than you should look the part"

Jay opened the box and pulled the ring out and handed it to Erin who raised an eyebrow as she looked at it.

"Jay...this is too much. Where did you get this?" Erin asked struck by the beauty of the ring in her hand.

"It was my mom's. Well is my mom's it belonged to my grandmother and she gave it to me to give to my wife. Well, you're technically my wife this week...so it goes to you" Jay explained his eyes never leaving Erin's.

She smiled softly at him and slipped it on her finger "Thanks Jay, It's beautiful"

Jay smiled and continued to stare at Erin. He didn't have to lift his gaze to feel the icy glare from Voight.

"I'm going to go and grab a magazine before we board. I'll be back" Erin said as she stepped away from Jay and Hank and walked to the magazine stand across the terminal.

"I'm not sure if I need to run this by you again Halstead but if you're going to continue to work in this unit. Erin is off limits. So any fantasy you have about her isn't going to happen" Voight's voice was low and his gaze hot as he made his feelings clear to the young man in front of him.

"I understand you completely, Sargent. No need to be a broken record" Jay held Hank's gaze as he looked at the older man who was more or less Erin's father.

Hank was about to respond, but was interrupted by Erin walking back up.

"You ready, Mr. Halstead?" Erin joked as she rejoined the two men she knew she could trust her life with.

"Sure, Mrs. Halstead" Jay joked.

He and Erin both laughed but their laughter quickly faded as they looked at Voight who wasn't seeing the humor in their joke.

"One Week. You know you're job. Don't screw up, this guy is capable of anything" Voight turned and walked away out of the terminal and out of sight.

"Was he that cheerful when you were a teenager?" Jay asked as he and Erin stepped out of the elevator and made their way down the hallway looking for thier suite.

"He used to be a lot more mellow" Erin said as she looked at the numbered doors as she made her way down the hallway "Until he walked in on me...Well, you're not old enough for that story"

Jay rolled his eyes as he followed Erin "Was this before or after he took you to the prom?"

Erin stopped and turned to look at him. "Are you still jealous?"

"You wish" Jay scoffed as he brushed past Erin and found their room

"You wish" Erin mumbled reaching into the envelope to hand Jay the key card to the suite.

"No, you wish" Jay said taking the key from her and opening the door to the suite.

"Oooo, daddy got the big suite" Jay exclaimed looking around the room from the doorway before stepping in.

Erin stood in the doorway and cleared her throat before folding her hands over her chest.

Jay turned around and looked at Erin. "Aren't you coming in?"

Erin gestured up to the door and said "Mr. Halstead, husband. You're supposed to carry me over the threshold"

Jay looked at his partner and said "Are you shitting me?"

Erin shook her head "You know, I never really understood that expression, but no I'm not shitting you"

Jay sat his duffel bag down and walked back over to Erin. He wrapped his arms around her slender frame and lifted her with ease Bridal Style. "You need to lay off the pizza there Lindsay, you're getting heavy"

"Kiss my ass" Erin furrowed her brow and wrapped her arms around Jay's neck as he carried her into their suite.

Jay laughed and walked into the suite touring the spacious room while still carrying his partner. "This place is amazing"

Erin looked around the room taking note of the single king sized bed against the far wall. "Um, Jay"

Jay looked at Erin before following her gaze to the bed. "Oh"

Erin loosened her grip around Jay's neck as he gently sat her down on her feet. "I guess one bed in a honeymoon suite makes the most sense"

Jay nodded and looked at Erin. Things were about to get real intresting.
