Jane sat at her desk and frowned while she followed every path of her thoughts. She chewed on her thumb nail and sighed heavily. With Mandy they had lost their chance to confirm her theory that it all was just about Samantha and because she didn't report the rape. And with Mandy's murder Anna and Simon were about to leave Boston to terrorize another city.
"You look like shit.", said a familiar voice and brought Jane out of her train of thought.
Jane looked up and drew her eyebrows together. "What the hell are you doing here?"
Masterson shrugged and took a chair to sit down at Jane's desk. "I was the one who had requested you and Korsak. I knew you would be interested in Mandy Bosworth's death."
"What made you think so?", Jane almost growled. "Because we invastigate a chain of murders that are connected to Samantha McKenna?"
Masterson smiled slightly and shrugged. "Don't forget ... I was also a member of your investigator team."
Korsak entered the bullpen and stopped dead as he saw the cause of trouble. "Oh, come on. You must be kidding me."
Masterson looked at him and chuckled. "I'm glad too to see you, Vince."
Korsak raised an skeptical eyebrow and sat down at his desk. "What brings you here?"
Masterson brought his notepad out of the inside pocket of his jacket and threw it on Jane's desk. "I thought my notes could be helpful for you. I have my copies. I don't need those anymore. Use them."
Jane sighed and opened slowly the notepad. She looked through them and took a deep breath. "Thank you."
Masterson bit his bottom lip and nodded. "You're welcome. I've heard that Lieutenant Foley also offered you his help."
"How do you know Foley?", Korsak wanted to know as he looked at their former colleague.
Masterson ran a hand over his unshaved chin and shrugged. "I met him once or twice when I still worked in Baltimore. He also helped me when I was a Rookie."
Jane looked at him and drew her eyebrows together. "You never mentioned that you also have connections in New York."
Masterson shrugged as he got up to his feet. "I already told you that I have a lot of connections, Jane."
Jane raised her eyebrows and bit her tongue.
Masterson smiled as he passed Maura as she entered the office. "Maura."
Maura turned her head toward him confused, and frowned. "Ryan.", she walked to Jane's desk and looked questioningly at her wife. "Why was Ryan here?"
Jane lifted Masterson's notepad up and shrugged. "He came by to give me this."
Maura's frown deepened and she took a deep breath. " I came upstairs because the results of Mary's blood are back."
Jane laid one hand on the folder and one against her forehead. "I can see that Mary had GHB in her blood."
Maura looked at her wife. "How did you know that?"
Jane stifled a laugh and opened the folder while Korsak chuckled. "Well, I think that is a pretty high dose."
" It's double that you would normally need.", Maura stated and crossed her arms over her chest. Jane sighed and looked at the autopsy report. "She wasn't raped? Well ... that is new."
Korsak looked at her and drew his eyebrows together as he followed his train of thought.
Jane was about to ask Maura her next question as she saw his expression. "Korsak ... what is it?"
Korsak got up to his feet and walked to the board. "You said that Mandy was Samantha's best friend. And best friends tell each other everything, right?"
Jane looked at Maura and shrugged. "Well, normally they do, yeah."
Korsak turned to Jane and pointed to Mandy. "And Mandy got killed because you wanted to talk with her about your theory that Samantha got killed. Isn't that an odd coincidence?"
Jane leaned back un her chair. "I don't believe in coincidences.", she said and looked thoughtfully at him. "So you think that we have a mole in Homicide?"
Korsak shrugged and furrowed his eyebrows. "It is possible, isn't it?"
Jane looked at Maura with raised eyebrows. "It would explain why the killer couple is always two steps ahead of us. But it could be anyone except for you, Korsak, Frankie, Cavanaugh and me."
Maura lifted her eyebrows and nodded as she tilted her head to the side.
Korsak looked at Jane. "And what a we doing now?"
Jane took the files and her notes and looked at him with a certain expression. "Now we move our work place to somewhere else."
Korsak nodded and took all his notes.
Maura took her phone and typed something into it. "I texted Frankie so he knows where to go."
Jane looked at both and exhaled loudly. "All right, let's move."

Frankie came into Maura's office later with four paper cups and placed them on the table.
Jane grabbed the cup with her name on it and sipped it. "That's what I needed. Thanks, Frankie."
Maura and Korsak grinned as they sipped their coffees.
Frankie rolled his eyes. "I always wanted to be a coffee deliverer. I always missed it since I am a Detective."
Jane rolled her eyes and grinned.
Frankie sat down next to Jane and leaned forward on his elbows. "So we are in Maura's office because the three of you think there is a mole upstairs. But that would crash the theory of just two murderers."
"Not really.", Jane said with a shake of her head. "When the male killer is really a cop it is possible that he has friends in here. Let's say the mole and the killer meet regularly in a pub somewhere in Boston, have a couple drinks, and talk about work."
"Which would make the Officer a mole without his knowing.", Maura said and Jane nodded in agreement.
"It would be a dirty trick.", Korsak mumbled against his cup.
Jane pursed her lips and lifted her eyebrows. "It would. But it would give Simon the opportunity to be up-to-date on our investigation. Which would explain why Mandy had to die."
"But you decided today that you want to question her.", Maura stated and looked with a frown at her wife.
Jane shrugged and opened Mandy's file. "All the lines come together at Samantha. The only logical next step would be to question Mandy. If I am right, then the mole came to the same conclusion and talked through the next steps with Simon . And Simon had all the information he needed."
"Sounds logical to me.", Korsak said and sipped his coffee.
Frankie frowned deeply and sighed. "But what are we doing with the cop who gave Simon all that information when we get him?"
Jane blinked a few times and took a deep breath. She had asked herself that question since they had found out that there must be a leak. What would they do with this cop. She shrugged. "We arrest him for aiding."
Frankie furrowed his eyebrows in disbelief. "Jane, you said yourself that the Officer probably didn't know that he helped a serial killer."
Maura inhaled sharply and looked at her wife.
Jane sat up straight and looked at her younger brother.. "Frankie, we are not allowed to talk about open cases. So it isn't an Officer, who is responsible for the case,. The Officer has to live with the consequences. I don't like it either. Believe me."
Frankie huffed and shook his head. "That's some bullshit."
Jane pressed her lips together before she licked them. "I know. But I didn't made the rules, Frankie."
"You also talk about open cases with Maura.", he argued.
Jane drew her eyebrows together and looked confused at her brother. "Wha ... Maura is the Chief Medical Examiner.", she laughed in disbelieve.
"I am responsible for the most of your cases.", Maura added.
Frankie rubbed his forehead and took a deep breath. "I know."
"Frankie,", Jane said softly and he looked at her. "Look, I know you are afraid that it could be a friend of yours and I understand you. But it could also be a Detective who's worked for years with Korsak and me in Homicide. But it doesn't matter. It doesn't matter if we know him. All that matters is that we catch Simon and Anna before they move on."
Frankie looked at her and nodded.
Korsak cleared his throat. "So ... what do we do next?"
Jane shrugged and furrowed her eyebrows. "I say that we go and pay a visit to Mandy's dorm tomorrow. Maybe we can get lucky and find something helpful."
Korsak nodded in agreement and took off his glasses.

Jane laid down on her side of the bed and rubbed her eyes with a groan.
Maura came out of the bathroom and leaned against the door frame. "Would you really arrest an Officer because he was aiding these killers, even he didn't know he did it?"
Jane leaned on her left elbow as she looked at her wife. "Yes ... yes, I guess I will do it. We all have to take the consequences. I would even arrest Korsak if he was the leak."
Maura raised her eyebrows surprised. "Would you really? Would you really arrest Vince if he was the leak?"
Jane looked away from Maura as she thought about the question. Would she? Could she? But then she looked back at her wife. "Yes, I would. I arrested you when I had to, didn't I?"
Maura walked to their bed and pulled off her dressing gown. "Yes, you did.", she said as she laid down and turned to Jane. "But when you arrested me I could see how hard it was for you, how painful it was for you."
Jane rolled on her right side and scrutinized Maura's face. "Because I did know that you didn't killed Brian Adams."
Maura took a deep breath. "You couldn't know it then, Jane."
Jane nodded slowly. "Yes, I did. Because I know that you are incapable of harming a living creature."
Maura raised her eyebrows. "But I can harm dead creatures?"
Jane furrowed her eyebrows and smiled a little. "Well ... you cut open dead bodies for a living."
Maura chuckled and kissed her wife's lips. "Yes, I do."
Jane grinned but sobered immediately. "And I know that Korsak isn't that stupid to talk about an open case.", she sighed heavily. "You know I love my job. But I hate it when we have to investigate a case that involves cops."
Maura smiled sadly and put a strand of hair behind Jane's ear. "I know, Jane, me too."
Jane pulled her wife closer to her or ... as close as possible. She sighed again. "You know ... your baby bump is starting to move."
Maura chuckled and hit Jane's shoulder. "I love you too."
Jane smirked and inhaled Maura's scent deeply before she closed her eyes and was embraced by a dreamless sleep.
