I watched the kids skating in the rink。 I listened to their laughter。 I thought of my daughter。 I thought of the four o'clock meeting。
I said； 〃Why are we sitting here？〃
〃Because；〃 he said。
So we sat there。 The teacher was rounding the kids up now； leading them off the ice。 〃Skates off here。 Skates off here； please。 That means you too； Alexander！ Alexander！〃
〃You know；〃 Connor said； 〃if you wanted to buy a Japanese pany； you couldn't do it。 The people in the pany would consider it shameful to be taken over by foreigners。 It would be a disgrace。 They would never allow it。〃
〃I thought you could。 I thought the Japanese had liberalized their rules。〃
Connor smiled。 〃Technically。 Yes。 Technically； you can buy a Japanese pany。 But as a practical matter； you can't。 Because if you want to take over a pany； you first have to approach its bank。 And get the agreement of the bank。 That's what is necessary； in order to proceed。 And the bank doesn't agree。〃
〃I thought General Motors owns Isuzu。〃
〃GM owns a third of Isuzu。 Not a controlling interest。 And yes； there are isolated instances。 But overall； foreign investment in Japan has declined by half in the last ten years。 One pany after another finds the Japanese market just too tough。 They get tired of the bullshit； the hassles； the collusion； the rigged markets； the dangō； the secret agreements to keep them out。 They get tired of the government regulations。 The run around。 And eventually they give up。 They just 。 。 。 give up。 Most other countries have given up： Germans； Italians； French。 Everybody's getting tired of trying to do business in Japan。 Because no matter what they tell you； Japan is closed。 A few years ago； T。 Boone Pickens bought one…fourth of the stock of a Japanese pany； but he couldn't get on the board of directors。 Japan is closed。〃
〃So what are we supposed to do？〃
〃The same thing the Europeans are doing；〃 Connor said。 〃Reciprocity。 Tit for tat。 One of yours for one of mine。 Everybody in the world has the same problem with Japan。 It's just a question of what solution works best。 The European solution is pretty direct。 Works well； at least so far。〃
On the rink； some teenage girls began to do warmups and a few tentative leaps。 Now the schoolteacher was leading her charges along the corridor past us。 As she went by； she said； 〃Is one of you Lieutenant Smith？〃
〃Yes； ma'am；〃 I said。
One kid said； 〃Do you have a gun？〃
The teacher said； 〃That woman asked me to tell you that what you're looking for is in the men's locker room。〃
〃It is？〃 I said。
The kid said； 〃Can I see it？〃
The teacher said； 〃You know； the Oriental woman？ I think she was Oriental。〃
〃Yes；〃 Connor said。 〃Thank you。〃
〃I want to see the gun。〃
Another kid said； 〃Quiet； stupid。 Don't you know anything？ They're undercover。〃
〃I want to see the gun。〃
Connor and I started walking away。 The kids trailed after us； still asking to see our guns。 Across the rink； the man with the newspaper looked up curiously。 He watched us leave。
〃Nothing like an inconspicuous exit；〃 Connor said。
The men's locker room was deserted。 I started going through the green metal lockers； one after another； looking for the tapes。 Connor didn't bother。 I heard him call to me； 〃Back here。〃
He was in the rear by the showers。 〃You found the tapes？〃
〃No。〃
He was holding open a door。
We went down a flight of concrete stairs to a landing。 There were two doors。 One opened onto a below…grade truck entrance。 The other went into a dark hallway with wooden beams。 〃This way；〃 Connor said。
We went down this hallway； crouched over。 We were underneath the rink again。 We passed throbbing stainless…steel machinery； and then came to a series of doors。
〃Do you know where we're going？〃 I said。
One of the doors was ajar。 He pushed it open。 The room lights were out； but I could see that we were in the lab。 Off in a corner； I saw a faint monitor glow。
We walked toward it。
？
Theresa Asakuma leaned back from the table； pushed her glasses up on her forehead； and rubbed her beautiful eyes。 〃It's okay as long as we don't make much noise；〃 she said。 〃They had a guard outside the main door earlier。 I don't know if he's still there。〃
〃A guard？〃
〃Yeah。 They were serious about shutting down the lab。 It was spectacular； like a drug bust。 It really surprised the Americans。〃
〃And you？〃
〃I don't have the same expectations about this country。〃
Connor pointed to the monitor in front of her。 It showed a freeze…frame image of the couple； embracing as they moved toward the conference room。 The same image； seen from other camera angles； was reproduced on other monitors on the desk。 Some of the monitors had superimposed red lines； radiating out from the night lights。 〃What have you learned from the tapes？〃
Theresa pointed to the main screen。 〃I'm not certain；〃 she said。 〃To be pletely certain； I would have to run 3…D modeling sequences to match the dimensions of the room and keep track of all the light sources； and the shadows cast by all the sources。 I haven't done that； and I probably can't with the equipment in this room。 It would probably require an overnight run on a mini。 Maybe I could get time next week from the astrophysics department。 The way things are going； maybe not。 But in the meantime； I have a strong feeling。〃
〃Which is？〃
〃The shadows don't match。〃
In the darkness； Connor nodded slowly。 As if that made sense to him。
I said； 〃Which shadows don't match？〃
She pointed to the screen。 〃As these people move around the floor； the shadows they cast don't line up exactly。 They're in the wrong place； or the wrong shape。 Often it's subtle。 But I think it is there。〃
〃And the fact that the shadows don't match means 。 。 。〃
She shrugged。 〃I'd say the tapes have been altered； Lieutenant。〃
There was a silence。 〃Altered how？〃
〃I'm not sure how much has been done。 But it seems clear that there was another person in that room； at least part of the time。〃
〃Another person？ You mean a third person？〃
〃Yes。 Someone watching。 And that third person has been systematically erased。〃
〃No shit；〃 I said。
It was making my head spin。 I looked at Connor。 He was staring intently at the monitors。 He seemed pletely unsurprised。 I said； 〃Did you already know this？〃
〃I suspected something of the sort。〃
〃Why？〃
〃Well； early in the investigation it seemed likely that the tapes were going to be altered。〃
〃Why？〃 I said。
Connor smiled。 〃Details； kōhai。 Those little things we forget。〃 He glanced at Theresa； as if he was reluctant to talk too much in front of her。
I said； 〃No； I want to hear this。 When did you first know the tapes were altered？〃
〃In the Nakamoto security room。〃
〃Why？〃
〃Because of the missing tape。〃
〃What missing tape？〃 I said。 He had mentioned it before。
〃Think back；〃 Connor said。 〃In the security room； the guard told us that he changed the tapes when he came on duty； around nine o'clock。〃
〃Yes 。 。 。〃
〃And the tape recorders all had timers； showing an elapsed time of about two hours。 Each recorder started about ten or fifteen seconds later than the previous one。 Because that was the time interval it took him to change each tape。〃
〃Right 。 。 。〃 I remembered all that。
〃And I pointed out to him one tape recorder that didn't fit the sequence。 Its tape was only running for half an hour。 So I asked if it was broken。〃
〃And the guard seemed to think it was。〃
〃Yes。 That's what he said。 I was letting him off the hook。 Actually； he knew perfectly well it was not broken。〃
〃It wasn't？〃
〃No。 It was one of the few mistakes that the Japanese have made。 But they only made it because they were stuck … they couldn't get around it。 They couldn't beat their own technology。〃
I leaned back against the wall。 I looked apologetically at Theresa。 She looked beautiful in the semidarkness of the monitors。 〃I'm sorry。 I'm lost。〃
〃That's because you are rejecting the obvious explanation； kōhai。 Think back。 If you saw a line of tape recorders； each one running a few seconds later than the one before； and you saw one recorder way out of sequence； what would you think？〃
〃That someone had changed the tape in that one re
