at owns the concession is sweating it out.

he wants it in triplicate that he's not at fault. so is he at fault? not unless a 300-pound machine can hop 20 feet and throw itself down the stairs. found his id in his wallet. it's, uh, aidan grant. 28, address on hoyt street. super said the kid lived alone. if he was going up to catch a train, he should have seen the machine in time to get out of the way. he was coming down. (male voice) detective khan, can i see you for a second? earbuds have been pulled off. i need to know what kind of music was on this. thanks. wi-fi card. a, um... an n-connector. he was building something? got a cell phone number for gisella. girls love a handyman. i met him last night at a party where he works. ubicool? my friend's the receptionist. aidan...what does he do there? computers. my friend said everything's hush-hush. what time did you and aidan get home?

maybe 1:00. he helped fix my internet connection. i better call in. so with fixing your connection he was here, what, a couple of hours? you have...a boyfriend? a jealous ex? no. i can't believe that-- [sighs] aidan was just so sweet. you moved this plant here? no, it's supposed to be over there. you see anybody out front last night? no. somebody was looking in. anyone you know do this? no. twenty knots. that's an interesting habit.

i can't imagine who'd want to hurt aidan. he was tremendously talented. he ever mention any stalking incidents, letters-- no. hey, could you unlock this, please? yeah. stealthwave. nice. uh, you won't find anything saved on there. we run everything off the server. what--what is this, special paint? yes, to block wireless signals. oh, just like the film on the windows. yes. so you're all... all sealed up in here, nothin' in or out. yeah, our clients demand security. well, who are you worried about, these people across here? no, those guys are still using metascan software.

if you're blocking the signals, why was aidan carrying a wi-fi card? well, not for this computer. oh, look. a perfect fit. uh, he wouldn't have been able to use it. unless he had an external antenna. a can-tenna. for 50 cents he beat your security. (boaz) oh, for god's sake. i have to check the server. excuse me. you know, it rained friday night. that can would have rust. he must have set it up saturday before the party. twenty knots. whoever left that... those people might have seen him. i was barely here five minutes on saturday. i forgot my tennis permits in my desk. right. kevin didn't stay very long. (goren) right. but-but

you came in early on saturday morning, 8:30? yeah, i was catching up. yeah, robert just got back from vacation. oh. you see anybody on the roof saturday? (kevin) i didn't notice anyone out there. you, robbie? saturday? no, i didn't see anyone. not even him? aidan grant. he works over at ubicool. nope, i've never seen him. are you sure? because his desk is practically right across from you. it's there, next to the window there. they had tinted films. hard to see in. you're saying you haven't even noticed they're using stealthwave computers? they are. and good for them. we've got a project to finish. sorry i couldn't help you. any programmer worth his chips would be drooling over a stealthwave, but kevin acts like he doesn't care. yeah, but he cared too much about what robbie had to say. and across the street, we got ubicool dissing the competition with one hand while building a security wall with the other.

not to mention, a dead hacker building antennas out of potato chip cans. busy little block. we don't need to get involved. let them sort it out for themselves. okay? whatever you want to do, kevin.

, but the knots are the same. it's a figure-eight. twenty knots on each. our friend kevin had a department of defense clearance three years ago at mit. he worked on facial recognition software. biometrics. there was something on aidan's desk. it was a...

a lip reading manual. facial recognition software that can also read lips. that uld be a potent surveillance tool. two guys from competing companies working together. one person might know. okay if we join you? our patrolmen are always talking about this place. you followed me. we got the feeling yesterday you might have more to say if kevin wasn't breathing down your neck. [sighs] i don't like lying. i did see that guy on the roof saturday. the guy in the picture. and so did kevin. i think kevin's up to something. i saw him over at ubicool last week, at night. he was with a tall thin guy. i-i-i think he's the boss there. kevin used to work for the military-- um, biometrics. do you know what that is? we do. and then ubicool shows up. and-and no one's ever heard of them, and they all have $7,000 computers. i mean, where are they getting that money?

where do you think? i don't want to know. i gotta get back. people will notice if i'm gone too long. now he's got me nervous. not half as nervous as him. (kevin) i think i told you everything i know yesterday. except the part about visiting ubicool last week. okay, sure. i'm trying to get a job there. but i have a contract with revocomp. it could get ugly. those photos, those are from the surveillance tape? i worked on facial recognition software for the d-o-d. i just happened to like the faces. anything else you didn't tell us? um, i saw that guy aidan on the roof. i didn't say anything because then i would've had to tell you i spoke to boaz at ubicool

about seeing his guy on the roof. what did he say about it? he said aidan was brilliant, but a loose cannon. always making trouble. boaz go up on the roof to check things out? i don't know. i left before the party ended. do you use this door much? only in the summer. do you notice anything missing in your place? no. are you trying to make me paranoid? i think you should be. uh, it looks like you might have a regular visitor. you know, they unscrew the hinges the door gets put on. take it off, they come in and out whenever they want. this is messed up. you should check your valuables. and your computer for spyware. i didn't tell you about kevin because if revocomp had found out i was even talking to him, they would have sued me and fired him. (female voice on computer) welcome, little ones, to 1984. aidan work on this? were designing a lip-reading program for deaf kids. (female voice on computer) wilder was free because he was never afraid.

the dialogue-- aidan wrote it? boy, aidan liked to undermine your authority. aidan had an outlaw spirit, but he never did anything to hurt the company. (eames) and the can-tenna on the roof? (boaz) that's just his way of thumbing his nose at me. you know, your computer's getting wi-fi reception. no, that's impossible. we have signal blocking paint on the wall. there's film on the window. the-the filaments embedded-- that's copper and aluminum? yes. don't know. it looks like somebody replaced the filaments with thread. (eames) here we were, thinking you were spying on everybody. somebody's spying on you. (matt) hope your brother doesn't mind i'm taking the last beer.

oh, hey, robbie. siena told me to help myself, so-- make yourself at home. robbie? you, uh, use the fireplace this morning? you still feeling cold? oh, um, i burned some junk mail. all they need to steal your identity is your name and address. [cell phone rings] hello? work was okay. i-i saw them over there today. it looked like they were searching. yes, yes the mouth. and then it's to the left? okay, i wasn't sure. all right, i will. good night.

lab finished checking aidan's home computer. no record he ever communicated with kevin, let alone conspired with him. uh, police work, look, we doubt people, we challenge them. we assume the worst about them. and somehow, it usually leads us to the truth. but this time it walked us right into a paranoid fantasy. aidan and kevin, biometrics, lip-reading, ubicool, and the military. but it wasn't just our fantasy. somebody else was happy to connect the dots for us. come on in, robbie. have a seat. you know, you can help us out. we're in over our head with all this high tech stuff. he's not kidding. until six months ago, we had rotary phones. uh, could you leave the doory open, please? uh, sure. it does get kind of stuffy in here.

do you know what...this is? yes, that's security film. you put it over windows to block out radio signals. we took a piece of this, uh, from one of the windows at ubicool. you see, the metal filaments, they've been replaced with common sewing thread. that's odd. ubicool, aidan, kevin--turns out they're not the bad guys. (goren) no, they're the victims of a conspiracy. the thread conspiracy. we found this on the roof, next to the antenna. (eames) and another one just like it outside hayden's girlfriend's place. they both had 20 knots. you ever seen anything like this? no. never.

could you excuse us for a moment? yeah. [door shuts] that looked to me like he was having trouble maintaining eye contact. he was looking at our mouths. when i scratched my eye, it forced him to look up. an experienced liar. well, not quite. when i talked about the thread, he...tilted his head to the right. that's the imaginative part of the brain, the one you use to lie. then he corrected and tilted his head to the left. like he's been coached? yeah, look at him. he wants to touch that thread. he wants to tie it into knots. it's a mechanism to keep himself under control. now that button, that's substitute behavior. he was taught that. someone must have told him that the knots were a dead giveaway.

for what? a psychotic condition? i hear psychotic, i think murder. if he's a murderer, somebody's teaching him how not to act like one.

oh, thanks. mm-hmm. i found an email he sent at 2:30 a.m. saturday to a k. pynchon. alibis him for the time of the murder. "working late..." he's trying to set up some kind of appointment. pynchon replied the same night at 3:46 a.m. or it could be trainer, or a therapist, or something? or a magician. according to the log file, pynchon read robbie's email at 11:35 sunday morning. neat trick, answering your email eight hours before you read it. well, robbie, he might've turned back his computer clock when senhis email to set up an alibi. mm-hmm. k. pynchon's email address is at newamc.edu. new amsterdam college. (pynchon) you read our emails? robbie's been my patient for two weeks. those were privileged communications. dr. pynchon, all we need to know is when you answered his email. it could have been early sunday. if i can't sleep, i get up in the middle of the night

and cull all my e-mails. do you mind checking your computer? no point, i clean it out after every session. (goren) so, uh, robbie doesn't go to school here. how did he find you his sister's in one of my classes. she introduced us. because we heard that he had trust issues. you're trying to get me to offer a diagnosis of robbie. i'm not going there, detective. you're a good doctor. you got me beat. now you're being insincere. i can tell. (eames) did robbie mention the people in the office across the street from him? a company called ubicool, that maybe somebody from there was spying on him? whether he did or not, i'm prohibited from saying. unless he threatened to harm them. if he had, i would have notified the police. you have a picture of a pitcher plant. they only grow in north carolina, in a bog. did you take this? yes. in croatan national forest. do you spend a lot of time in the outerbanks? some.

on vacation. you know the area? yeah, i had a girlfriend who worked on cape hatteras. no, you didn't. you're lying again. no. why do you think that? you were making eye contact. but when you brought up this girlfriend, you dropped you gaze to my mouth instead. is that what liars do? i'm afraid it's about that time. now we know where robbie learned his tricks. she said that she's been seeing him for two weeks. since the murder, what timing. i wonder what prompted his sister to get him help. there was no crisis. my brother had been wanting to see someone for a long time. it was always a question of who, and i got a good vibe from dr. pynchon. your super told us you and robbie have been living here for four years. since our parents died. you take care of him. she schedules her classes around his--

what, his moods? i'm just gonna go sit over here and shut up. having a boyfriend could really throw robbie into panic. i don't know where you get this idea about my brother. super smart people like robbie are often insecure. it's because they are so perceptive. saturday night, weekend before last, where you here? we spent the night at matt's. and sunday? you see him? in the afternoon, we came back here and he showed up. he was all-- he was tired. he was at his office all night. matt, if you need to swing by your place before class, you're going to be late. we'll let you kids do your thing. hey, matt. aw, man, come on... we didn't mean to get you thrown in the doghouse. but you know she's always gonna put her brother first as long as he's around, right? you said when he came home sunday,

he was all...what? upset? no, he was super mellow. he even sat next to me on the couch. super mellow. and how did he look-- his clothes, you see any stains, anything that looked like blood? just this spot on his shirt-sleeve here-- it could've been blood-- if she sees me with you-- his boss told us that when he got back from vacation, he was a new man. did you see that too? yeah, he's been friendlier, except for complaining about my music, which he never used to do. your music, you mean, what you were listening to upstairs? do you know where he went on vacation? siena says florida, but he must have spent all his time [cell phone ringing] in the shade. look, this is-- i really got to loose you guys. hey sweetie, just about to get on the subway... the blood on his shirt near his triceps. that's where he'd get an injection. there's no record that he got his injection at the hospital sunday morning.

you know, i'm wondering about this vacation. when robbie got back he started to complain about house music. now that's the same kind of music that aidan had on his music player. the one with the missing earphones. robbie must've taken them. there was something about it that bothered him. okay, thank you. the mental health building is locked up on sundays. pynchon doesn't have a key. but she has a house on long island. well, if robbie went there after killing aidan, he would have been agitated. she would have given him something to calm him. and if he washed his clothes, he might have left something behind. you said after they talked to me, they'd stop. we are going through this process together. you remember, you agreed. i couldn't take it anymore. i wanted the light. when you trust me, robbie, trust me without conditions... you'll be free. okay.
