Korsak stood up and took a evidence bag then he took the letter. Dark memories of Dennis were awake. " It reminds me of ... "

Jane buried her face." Me too. Crime's back. "

Maura sighed worried. " Crime has never leaved Boston."

Jane growled.

Frost looked questioningly at all. " Reminds you of what? "

Maura took the letter and read out loud. " Dear Detective, if you do not deciphering these symbols in a predetermined time then people will die. ", Maura paused. " Oh no! "

Frost lost his patience. " Oh, no, WHAT? "

Jane looked at him reproachfully. " Hold your horses! Ever heard of the Zodiac Killer? "

" Who doesn't? He killed five people. "

" And has claimed that he killed thirty-seven. ", Korsak added thoughtfully. " He also corresponds with the police. He was acitve in the 60s and 70s. "

Maura pulled her eyebrows together. " Yes, but hasn't he operated in Nothern California? "

" And maybe Nevada too. ", Jane said and looked at her wife. "Okay, maybe it's just a weirdo who just wants attention. "

Korsak looked at her seriously. " We should take it serious. "

Jane made a face. " But I don't want to. ", she wailed.

Maura rolled her eyes and took the two letters. " I'll let them examine for fingerprints. "

Jane nodded slowly and held out the ensured envelope. " Test it too, please. "

Maura took it. " Okay. "

" Thank you. "Jane clapped her hands and took a deep breath. " Okay, with what we'll start? "

Korsak scratched his hairy chin. " I would advance that we collect everything about the old Zodiac cases. "

Frost nodded and began to tip at his keyboard.

Jane sighed and took her receiver.

Korsak looked at her questioningly. " Who are you calling? "

Jane scratched her right eyebrow. " Our colleagues in California. Maybe they let us look in their files. "

Korsak nodded slowly. " Good idea. "

Jane smiled weak. " Um ... this is Detective Jane Rizzoli from the Boston Police Department. I have a few questions about your Zodiac case. "

Jane came into the lab and saw how Susie, another lab technician and Maura worked at the documents. " Have you just started? "

Maura looked up and bit her lower lip. " We don't only on your cases, Jane. We were busy. "

Jane waited for the conventional ' I'm sorry ' but it didn't came. " How rude. "

Maura looked up confused. " Excuse me? "

A mischievous smile laid on Jane's lips. " You should only work on my cases. "

Maura sighed loudly. " We are NOT your personal institute. "

" Dam ... ", Jane paused when she saw Maura's gaze and began singing to dance. " Dam, dam, dam dam, dam ... "

Maura rolled her eyes and pulled off her gloves. " Are you here for a particular reason? "

" I didn't realized that I need to have a reason to be here. ", Jane replied and Maura sighed. " Yes, I have. "

Maura waited patiently.

Jane exhausted her luck and stared at her wife without speaking. Then she had enough. " I was wondering if you know a good cryptographer. "

Maura made her way to her office. " I know a few. "

Jane followed her and clasped her hands behind her back. " Of course you do. "

Maura looked through her address book. " I also know a few symbologist. "

Jane closed the address book and frowned. " I was more thinking of a blonde, green-eyed, attractive woman who happens to work here. "

Maura tilted her head to the side and frowned deeply. " Jane, I am neither the one nor the other. I could make significant mistakes. "

Jane stamped impatiently on the floor. " MAURA, ", she said whiney. " I have neither the time nor the patience to grapple with your strange cryptographers or symbologists. What can they know that you don't? "

" A lot. And they have the right equipment, I don't. "

Jane grabbed Maura's wrist and pulled her with her. " Come on. ", she growled through gritted teeth.

" Jane! ", Maura cried out in surprise.

She sat at the group table in the bullpen, staring at a faxed copy.

Jane waited patiently, wringing her hands. " And? "

Okay, not so patient.

Maura shrugged and raised her eyebrows. " I ... ", she sighed. "I have no idea, Jane. "

Jane made a grunting noise. " You're a genius, Maura. This must be a puzzle for you. HEY, puzzles are fun. "

Maura took a deep breath. " I have studied medicine, Jane, and not symbolism or cryptology. I need books to be able to begin. "

Jane rolled her eyes. " You have tons of books. "

" Not of this kind. "

" Jane, ", Korsak calmed his former partner. " Doc's right. If you want her to try it then you have to let Maura make preparations. "

" Alright. ", Jane sighed. " Obtain everything you need to decrypt. We go through the facts and wait for the original files. ", she looked at her watch. " They should be here in forty-six hours. Let us pray that we have a larger time window. "

Jane came heavily laden in the house. " I thought you said that you need a few books. I couldn't guess that you're buying the whole book store. "

Maura closed the door and locked it. " I did NOT say that I only need a few books, Jane. You better listen. "

Jane dropped the bags and gasped. " I'm a awsome listener. "

Maura poured herself a glass of wine and left the statement without a comment.

Angela watched them and grinned.

Jane sighed and kissed her cheek. " Hey, Ma. Has Alexis made problems? "

" Not at all. ", Angela replied. " I took her to bed a half hour ago. "

Jane grabbed a beer from the fridge. " Thank you. Tomorrow comes the babysitter and you're released. "

Angela looked at her reproachfully. " I don't mind taking care of Alexis. "

Jane took a sip of her beer. " I know. But ... you never want to work again or be with your bosom pal? "

Angela rolled her eyes. " Stop calling Sean my ' bosom pal '. I don't call that Maura either. "

Jane hugged Maura from behind and her left hand crept to her breast. " But ... Maura's my bosom buddy. "

Maura gasped and slapped the naughty hand before it reached its destination.

Angela just shook her head.

Jane winced and slapped gently Maura's buttocks.

" Why all the new books. ", Angela wanted to know.

Maura sipped her wine. " For our current case. Jane doesn't want to ' grapple' with my odd experts. "

Jane opened her mouth to retore something, but closed it again as she felt that Maura was right.

Angela's curiosity was excited. " What case? "

Jane streched and stifled a yawn. " It's not really a case. We just got a hint."

" A ciphered hint. ", Maura replied.

" And you decipher it. ", Jane said.

Maura sat down at the kitchen island and sighed, already forgotten Angela's presence. " Jane, the best symbologists and cryptographers are working on the Zodiac case for DECADES, and its still not solved. "

" They don't have you. ", Jane argued.

Maura frowned. " I'm a doctor, not a cryptographer. I have to read up on that subject myself first. Do you understand that, Jane? READ UP! "

Jane waved. " I'm not deaf but I have trust in you. "

Maura dropped her shoulders.

" Is he back? ", Angela threw into the room.

Jane made a face. " He's not back, Ma. It's just a weirdo who wants attention. There's not even a murder. But we have to investigate. "

Maura smiled politely at Angela.

Angela had suddenly both women's necks in a death grip. " Oh, my babies. Don't risk your lifes again. "

Maura gasped for air and tapped semi-conscioused at the elbow of her mother-in-law.

Jane tried to breath and tried to squirm out. " Ma ... ", she choked out. " Ma ... air. We need ... breath ... We can't ... "

Angela broke the stranglehold. " Oh ... sorry. "

Maura felt dizzy as she sucked air into her lungs and her head was as red as a tomato.

Jane rubbed her neck and gasped. " Gee, Ma! Want to be arrested because you strangulate us cause you're worried about us? Kids killed by the worried Mama Rizzoli. GREAT! "

Maura laughed, breathing heavily.

Angela threw her arms in the air. " I'm just worried about my children. "

" Your concern has almost killed us right now. ", Jane replied.

" Jane, your mother is just ... ", Maura said reassuring.

" She's what?", Jane cut her off. " Loud, pushy, overprotective, broody? A helicopter mom? "

Angela hit Jane with a huff after the description on the arm.

Jane winced and rubbed the spot.

Maura laughed and took a deep breath. " Well ... she's just ... Angela. "

Angela nodded slowly in agreement.

Jane rolled her eyes and emptied the beer bottle.
