When Sister Kate takes Uncle Ka and Helsing to the Western Union bar, von Roe is gathering all the members of the Western Alliance to celebrate the farewell of Jack Koonan's body.

When von Roe saw that Sister Kate and the three of them had come to his bar again, he walked up to Sister Kate with an unkind face and said, "I hope you have come here to mourn the dead, and if not, I will be very grateful that you will get away from me." ”

Sister Kate said without showing weakness: "You lied! You know very well how Jack Koonan died, you made a show in front of me and beat 'Suzaku' half to death, but you actually killed Jack Koonan because he denounced you to the FBI. ”

"Enough! Inspector Beckett, I won't allow you to slander him, especially tonight! Von Rocker said viciously.

"I was told by an FBI agent that Jack Koonan was going to trade news with the FBI, and was killed as soon as he left the FBI's New York office and returned to his residence." Sister Kate said-for-tat.

Von Rourke heard Sister Kate say this, and after being silent for a while, he slowly said part of the inside story, it turned out that it was because someone was selling drugs and products on the territory of the Western Alliance, so Von Rourke sent Jack Koonan to find out who was so bold and dared to violate the rules set by him von Roch under the nose of the Western Alliance, so it must have been that group of people who killed Jack Koonan.

After von Roe finished speaking, the three Kate sisters were invited out of the bar by the Western League. After leaving the bar, Sister Kate did not return to the bureau directly, but stopped and waited at the alley at the back door of the bar, and soon a woman ran out in a panic.

Sister Kate then drove her to the police station and placed her in the reception room for a conversation. In the course of the conversation, Sister Kate learned that the woman's name was 'Morley' and that she was Jack Koonan's girlfriend, and she didn't know exactly what Jack Koonan had found, but what she could confirm was that Jack Koonan was not killed by von Roch, and on her last night with Jack Koonan, Jack Koonan gave her a key and told her to give it to the police if things went bad.

Sister Kate took the key and immediately recognized it as the key to the station locker, so Sister Kate led everyone to the nearest station to the crime scene, found the locker that the key could open, opened the locker, and everyone was surprised to find that the locker was full of videotapes of 'Johnny Wang'.

When Sister Kate took out the videotape box from the cabinet, she realized that something was wrong, and after opening the box, she found that the mezzanine in the box was stuffed with drugs and products, so Sister Kate notified the police to take the videotapes back to the police station. After careful investigation and evidence collection, everyone came to the conclusion that the tapes were shipped from Hong Kong before they were smuggled, so Johnny Wang must not be involved in this matter.

So Sister Kate and her entourage rushed to a small marketing venue of Johnny Wang, where they caught Johnny Wang, who was walking barefoot on the coals.

Bringing the goods back to the police station, under the interrogation of Sister Kate and Uncle Ka, Johnny Wong confessed about using the video tape to carry the smuggled goods, but he would rather be imprisoned than say who was the mastermind.

While Sister Kate and Uncle Card were sitting in the break room, Renee brought Uncle Card's friend Dr. Clark Murray to Sister Kate. Renee introduces Dr. Murray, a forensic pathologist who was invited by Renee to assist in the identification, to Sister Kate.

Although Sister Kate felt that Renee's behavior was very abrupt, she still politely greeted Dr. Murray and introduced Uncle Ka to him, but Uncle Ka told Sister Kate that he knew Dr. Murray, so Sister Kate finally felt that something was wrong.

After everyone sat down, Dr. Murray took out Jack Kunan's forensic examination file, pointed to the photo in the file and explained the situation to Sister Kate, who wondered why Renee would so solemnly invite a forensic pathologist to assist in the case, and solemnly took Sister Kate to the conference room and closed the door to explain the case.

In the end, Renee carefully explained the reason, and it turned out that according to the results of the forensic examination, the murderer of Jack Kunan was undoubtedly the murderer of Sister Kate's mother.

After Dr. Murray left, Sister Kate immediately became angry with Renee and asked her why she didn't tell her the news in the first place. Renee patiently explained to Sister Kate that she just wanted to wait for the evidence to be conclusive before telling Sister Kate.

In the end, Sister Kate turned around and left the police station without saying a word, and Uncle Ka originally wanted to catch up, but was stopped by Helsing, so Uncle Ka followed Helsing to his FBI office.

Hersin took out the best whiskey from the wine cabinet, poured two glasses, handed one to Uncle Ka, and said, "Beckett is talking to her father now, so don't go and join in the fun, you better prepare first." ”

"(°ー°〃) What are you going to prepare?" Uncle Ka said confusedly.

"Oh, it's nothing, it's just that before this case is over, you will be held hostage by the murderer at the police station, and then Beckett will have no choice but to shoot her in order to save you, so you can't know why her mother was murdered." Helsin's casual words sounded like thunder in Uncle Ka's ears.

“！！！ Yes! So what am I going to do??? If I don't go to the police station, won't this happen? Uncle Ka hurriedly asked.

Helsing shrugged his shoulders and said: "Impossible, if you don't show up, naturally other people will be taken hostage, the murderer will still be shot by Beckett, if you tell Beckett, then the murderer will be shot by Captain Roy, if you tell Captain Roy and Beckett, then ......"

"Then the murderer will be shot by someone else...... I understand, I understand. Uncle Ka kept nodding his head to indicate that he had understood.

"So you have to be prepared, how to ensure that the murderer does not die in this situation, I have already given you a hint." Helsin said.

When Uncle Ka heard Helsin's words, he sat down in his chair with his glass in his hand, and it was Helsing who said to him: "You should go home, and Beckett will come back to your house to look for you after talking to her father." ”

When Uncle Ka heard this, he immediately put down the wine glass in his hand, thanked Helsin, and hurried home. As soon as Uncle Ka returned home, Sister Kate knocked on the door of Uncle Ka's apartment.

Uncle Ka immediately welcomed Sister Kate into the door, and Martha also dragged Alexis to the bedroom on the second floor, leaving the living room to Uncle Ka and Sister Kate.

Uncle Ka looked at Sister Kate's speechless appearance, and said seriously: "As long as you need it, I am willing to do anything for you, including doing nothing, if you need me to do nothing." ”

After listening to Uncle Ka's words, Sister Kate thought carefully and said, "I want to find out the murderer of my mother." ”

"Then we'll have to pry Johnny Wang's mouth open and come up with a name." After listening to Sister Kate's words, Uncle Ka said with a meaningful smile.

After Sister Kate and Uncle Ka reached a consensus, they immediately came up with a way for Johnny Wang to take the initiative to explain. The two immediately returned to the police station and went to the detention cell where Johnny Wang was temporarily held, and told him that he had been acquitted due to a low-level mistake. Johnny Wang immediately said that you are not teasing me, and if you tell me to go out now, then the person behind me will definitely think that I have cooperated with the police, and I am not going to die.

Uncle Ka made it clear, we are just teasing you, you have two ways now, either cooperate with the police to let us catch the murderer, or we will clear you out so that the murderer thinks that you are cooperating with us and then kill you, young man, you choose.

Johnny Wang strongly protested against the rogue behavior of Sister Kate and Uncle Ka, but in this kind of situation, he had to obediently confess that the person behind him was Jack Koonan's own brother - Dick Koonan!

During the interrogation, Sister Kate learns from Johnny Wang that Dick Kunan has hired a professional killer named "Rathborne", and this person is the murderer of Sister Kate's mother! However, Johnny Wang did not know how to find this man, and only Dick Kunan could contact Rathborne, so Sister Kate ordered Dick Kunan to be taken back to the police station for interrogation.

In the interrogation room, Dick Koonan, after arguing with Sister Kate, made a request that he hand over Rathborne if the police were willing to provide him with immunity.

Sister Kate found Hersin, and before she could speak, Helsin handed her an envelope. Sister Kate opened the envelope and saw that it contained a document of immunity issued by the court. This time, Kate didn't ask any questions, just said thank you, turned around and left Helsin's office, back to the interrogation room.

In the interrogation room, Sister Kate handed the immunity document to Dick Kunan's lawyer, and with the lawyer's approval, Dick Kunan began to confess everything about Rathborn, and after realizing that she could not get any clues to capture Ruthborne from Dick Kunan's description, Sister Kate asked Dick Kunan to send a message to Ruthborne and ask him to assassinate Johnny Wang, and Dick said that if he wanted to hire a killer, he needed to pay $100,000 in advance.

When Uncle Ka knew that Sister Kate could not apply for $100,000 to advance the employment payment, he expressed his willingness to pay out of his own pocket to help Sister Kate solve her problems, and finally Sister Kate reached an agreement with Dick Kunan that as long as Lathborne accepted the commission, he could be acquitted.

What happened then was not as good as expected, when Uncle Ka wired $100,000 over, an email confirming the employment was sent from the other side, of course, the other party used a disposable mailbox, and the NYPD technician said that it could not be traced.

The 12th Precinct dispatched the whole area, first let an Asian police officer disguise himself as Johnny Wang, who was escorted, and then mobilized all the police forces to monitor the entire route of the escort vehicle at all times, and make sure to capture it when the assassination was carried out by Rathborn, but until the end of the entire escort trip, there was no assassin appearing, and the operation failed completely.
