Background: The night after the killer murdered at the university, Jennifer Buchanan is almost murdered. She had become drunk and told her husband Joe, during his service and in front of his congregation, that she wanted a divorce. She returned to Rex' apartment and fell asleep. After he left her to sleep it off, the killer trid to strangle her. However, Rex returned and was able to stop the killer before he could finish her off. Rex chased him down an alley, to the pier, but the killer jumped into the water. Later the police arrived and interrogated him. He leadsthem to where he last saw the killer and the found an expensive bag, which the killer was carrying. Later Nora recognized it as being similar to a bag which Troy MacIver owned.

Al, as Michael, and Marcie visited Ron, her brother, at the hospital. Michael examinined him -- he had suffered a severe allergic reaction.. Marcie meanwhile saw Jennifer being brought in on a stretcher. She immediately called Joe and told him. Al told them that since Ron was in the hospital that it means he definitely has an iron-clad alibi and is innocent. He also tells Marcie that that means he too is innocent. Michael/Al wonders if she ever believed he was the killer. She tod him that she did not.

Antonio helped Evangeline Williamson, track down a witness in a court case, who is a student at the university. They went to her lab at the university, and opening a closet door they found her murdered bodied. Near her are a cheap music box by her feet, a red scarf around her neck, and heart shaped tears painted on her cheek. However, Antonio immediately noticed that it is a scarf and not leotards, that the music box is cheap and has no dancing ballerina; a cop discovered that the hearts are painted with her blood not the lipstick the killer always used. Later they discovered that student was murdered by the person she was trying in court, he thought that this way he could silence her and blame it on the Music Box Killer. Antonio also figured out that there are a connections between all the victims and Nora Buchanan: Nora is Jewish, as was one of the earlier victims; the P.I. who was murdered had studied law at one time, Nora is a lawyer; one of the earlier victims had been married to an African-American man, as had Nora; Madison Kensington had be charged by Nora.

At the same time, John McBain tracked the killings on a map, from the first killing to the last three in Llanview, connecting them together he created a rectangle on the map, similar to the shape of a music box. Bo arrived and he gave John a city map. Using the killings in Llanview he created the three sides of another rectangle -- inside the larger rectangle. He then estimated the location of the next killing. Bo became concerned because the next murder, if the pattern continued, would be directly in the middle of his father's estate, and worst still his niece Sarah, the rock singer Flash, lives at the mansion -- she too has a connection to Nora. Fearing the worst, he set up around the clock guards for her.

Earlier that day Bo received a special letter from the killer. There are series of letters and numbers on the list. Later he showed John a copy of the letter. The D.A., Daniel Coulson, and his son -- a musician with Flash's band and her boyfriend -- noticed the numbers and immediately commented that it reminded him of musical notes, and tempo. They ask him to try and crack the code. He theorizes that the numbers, "4/4" and "4/5" represent tempo. After some time he in fact cracked the code, using a piano to figure out the notes he came up with the word "F-R-O-N-T." Bo John wondered if the numbers was an address, because there is a Front Street in town. Eventually they discover ed that it is in deed an address. It belongs to Rex, where Jennifer nearly was murdered; AND that it once belonged to Dr. Troy MacIver.

Scene One: Nora has gone to see Troy at Statesville Prison. Troy is equally calm and yet spooky the whole time. He assures her he is cured. He wants to know, and seems to really care, if she hates him. She tries to assure him she does not. She is confused by his behavior, which seems too calm and normal.

Scene Two: Bo is disturbed by all the clues which point to Troy, and which seem to indicate that Nora is connected to the killings. He and John McBain are trying to discuss the case. Bo says he wants to call in someone for help, Prof. Haver from the university. John is familiar with him as well, the F.B.I has called him in on various cases, including the D.C. area sniper shootings of last year.

Scene Three: Police Station, Commissioner Bo Buchanan's office. Bo, Agent John McBain are talking to Rae (Gretel) Cummings, a psychologist at the university, and Dr. Haver about Troy MacIver. Bo is sitting at his desk, McBain is standing in back of Bo, eating Chinese take out from a carton using chop sticks., and Rae and Haver are sitting in front of the desk, next to each other. Rae listens to Stephen. The scenes starts in mid-disscussion.

Stephen and Rae seem to be almost flirting as they discuss Troy's condition. They each nod their heads in agree, why looking at each other, somewhat pleased. Bo and John McBain get annoyed, and want facts and not psycho-babble.

BO: Ahh, excuse me, what are you guys talking about?

RAE: Oh....

STEPHEN: (They both turn towards Bo) Oh, I'm sorry we were just discussing why Dr. MacIver was so fixated on his wife's death in Africa (Rae turns back to look at him, see seems taken by the good professor).

JOHN: Let's.... let's forget about Africa. No more Africa! (Puts down his food) All we want to talk about is the Music Box Killings, okay. So maybe we can figure out what is (motioning with his hands) tying all these together. That's.... that's what we want to focus on right now.

BO: (Nodding in agreement, and cutting in) We think it's Nora Buchanan.

STEPHEN: Yes, yes I read your file on that, it's a real possibility. But in fact, this may well long pre-date the A.D.A. (As he talks Bo listens intently) Dr. MacIver described to me a woman he loved deeply just as he was entering medical school. She rejected him. (Bo becomes more interested) rather cruelly in fact. She was a former ballet dancer, entering law school. Not unlike Ms. Buchanan who's won some dance competition and is an attorney.

Bo looks over toward John, who starts to ask questions.

As Haver describes his theory, Bo walks towards the door and looks through the Venetian blinds, and motions to someone.

Bo turns and opens the door. It is Nora, back from seeing Troy.

Haver watches, he looks oddly, as if he is not too pleased to hear this. Why?

Rae watches him, as if she is trying to analyze him. McBain cuts in. Haver listens and watches Nora.

Scene Four: Troy caresses the photo and looks oddly, is he obsessed. He then says Nora's name.

Scene Five: Later in the day Asa Buchanan, Flash's grandfather, wants to know why a policeman is outside his mansion. Bo finally tells him that they are afraid that the killer will strike at there and that Flash is possibly his next victim. Asa gets angry that he was not told, and demands a whole army of cops protect her, and he tells her that she is forbidden to leave the house. A phone rings and she answers it, there is no one on the other end, suddenly music begins to play, it is the same song which played on the music boxes found by all the victims.
