Jane, Korsak and Frankie arrived on the Forest Hills Cemetery after they had checked were Lisa Sherman's grave was and discovered a figure that kneeled in front of a grave stone. Jane put her left hand to her gun and nodded to the person.
Frankie and Korsak nodded and put their hands to their gun too.
They slowly neared to the person and concentrated on their next steps.
Jane swallowed hard and licked her lips. "John? John Sherman?"
The man stopped in his movement but didn't looked at the cops. "I guess you must be Detective Jane Rizzoli."
Jane looked briefly at Frankie and Korsak, who were wide aware of the situation and nodded. "Yes, that is me."
John still didn't turned around. "Do you understand why I had to do all of what I have done?"
"Because you wanted justice for your sister Lisa who got a victim of the gang war."
"I had to do this because you are incapable to protect innocent people. You rather sit at your desks and do nothing. Instead to go on the streets and lock away all those bastards that kill innocent women who are on their way home. You do nothing to prevent us."
Jane looked at the back of his head and furrowed her eyebrows. "I can understand that you are angry. That you are angry at the Police. But why did you killed those men? What did they to you?"
John sighed and slowly stood up. "I had to get your attention. And as my experiences have had shown me ... you cops need a little incentive. I had chosen them randomly besides Jason Tucker. He was just a burden."
"What about Detective Frost?", Korsak asked.
John's shoulders slumped and he sighed. "I ... needed a leverage. And what doesn't work better than a murdered cop? So you would do what you can to find me and stop me. And I would say that it worked pretty well, didn't it?"
Frankie clenched his teeth and his facial muscles twitched.
Jane saw his reaction and held a hand up. "John, I hope you are aware that we will arrest you."
John turned to her and held his wrists towards her. "Do what ever you need to do."
Jane looked at Frankie and nodded slowly.
Frankie grabbed his handcuffs and put them around John's wrists while he read John his Miranda rights.
Jane exhaled loudly and rubbed her face with both hands.
Korsak put an hand on her shoulder and frowned worriedly. "You okay?"
Jane looked at him and forced herself to smile and nodded slowly.

The group of four sat in the Dirty Robber and sipped their drinks in silence. They had solved the case but something still didn't felt right. Maybe it was because they had one of them because a desperate brother tried to open the eyes of the citizens that the Police of Boston was one huge failure. Of course they all, the citizens and the law enforcement members, were aware that there were always some bad apples at the Police Departments. But John Sherman had the opinion embedded that every single cop was incapable to prevent the city from violent felony offense.
Maura looked at her wife and rubbed soothing circles at Jane's back.
"I thought it would feel great after we catched the scumbag.", Korsak said as he stared into his mug of beer.
Jane looked up and frowned. "Yeah, me too. But instead I feel burned-out."
Frankie looked long at her and raised his eyebrows. "You should take some days off."
Jane shook her head and sipped her beer. "Nah, I'm good."
But at this time she didn't knew how hard the loss of Frost would hit her and how many times she would have to struggle with the need to blame herself for what had happened. And she didn't knew that she would doubt her own skills as a Homicide Detective. And that she would withdrew herself immensely from the job she always loved from the bottom of her heart. She also didn't knew that she would play with the thought to give away her badge all by herself to have time for Maura's and her daughter.
She didn't knew that she would offer Frankie her place in the Homicide unit as soon as he had promoted.
All those thoughts came into her mind right now. Because all that mattered was that the four of them sat in the Dirty Robber.
Jane sighed and raised her mug. "To Frost. An great Detective and a better friend who lost his life in the line of duty."
Maura raised her mug as well and smiled a little. "To Frost."
Korsak and Frankie raised their mugs too. "To Frost.", they said in unison.
Jane out the mug to her lips and for a moment she thought she saw Frost who stood at the bar counter, grinning, with his own mug that he had raised. She smiled and sipped her beer.
