Perhaps； he Schofield thought that was what had happened here。
And then suddenly he had another thought。 A more disturbing thought。
〃Gant； when did the SAS team arrive in the cave？〃
〃I'm not sure； somewhere around eight o'clock； I think。〃
〃And when did you arrive in the cave？〃
〃We left the diving bell at 1410 hours。 Then it took us another hour or so to swim up the tunnel。 So I'd say about three o'clock。〃
Eight o'clock。 Three o'clock。
Schofield wondered when the original team of divers from Wilkes Ice Station had gone down to the cave。 There was something there； something that he couldn't quite put his finger on just yet。 But it might have been able to explain 。。。
Schofield looked at his watch。
9：50 p。m。
Shit； time to go。
〃Gant； listen； I have to go。 There's a window in the solar flare ing over the station in ten minutes and I have to use it。 If you and the others are safe down there； do me a favor and look around that hangar。 Find out everything you can about that plane； OK？〃
〃You bet。〃
Schofield clicked off。 But no sooner had he done so than he heard a voice from somewhere high up in the station。
〃Lieutenant！〃
Schofield looked up。 It was Renshaw。 He was up on B…deck。 〃Hey！ Lieutenant！〃 he shouted。
〃What？〃
〃I think you better see this！〃
Schofield and Kirsty entered Renshaw's room through the square hole in the door。
Renshaw was standing over by his puter。
〃It's been on all day；〃 Renshaw said to Schofield； 〃but I only looked at it just now。 It said I had new mail； so I brought up my e…mail screen and had a look。 It came in at 7：32 p。m。 and it's from some guy in New Mexico named Andrew Wilcox。〃
〃What's it got to do with me？〃 Schofield said。 He didn't even know anyone named Andrew Wilcox。
〃Well； that's the thing； Lieutenant。 It's addressed to you。〃
Schofield frowned。
Renshaw nodded at the screen。 On it was a list of some sort； with a message written above it。
Schofield read the message。 After a moment； his jaw dropped。 The e…mail read：
SCARECROW；

GOOD HUNTING； HAWK
Schofield stared at the e…mail for a moment； stunned。
〃Hawk〃 was Andrew Trent's call sign。
Andrew Trent； who…Schofield had been told…had died in an 〃accident〃 during that operation in Peru in 1997。
Andrew Trent was alive。。。。
Renshaw printed off a copy of the e…mail and handed it to Schofield。 Schofield scanned the e…mail again； thunderstruck。
Somehow； Trent had discovered that he was down in Antarctica。 He had also discovered that a secondary team was on its way to Wilkes。 Most disturbing of all； however； he had discovered that the United States Marine Corps had already listed Schofield as officially dead。
And so Trent had sent Schofield this e…mail； plete with a list of known ICG informers； in case Schofield had any traitors in his unit。
Schofield looked at the time of the e…mail。 7：32 p。m。 It must have been transmitted via satellite during the 7：30 p。m。 break in the solar flare。
Sctiofield scanned the list。 A couple of names leaped out at him。
KAPLAN； SCOTT M。 USMC GNNY SGT
Snake。 As if Schofield needed to know that Snake was a traitor。 And then：
KOZLOWSKI； CHARLES R。 USMC SGT MJR
Oh； God； Schofield thought。
Chuck Kozlowski。 The Sergeant Major of the Marine Corps； the highest…ranking enlisted soldier in the Corps； was a member of the ICG。
And then Schofield saw another name that made him freeze in horror。
LEE； MORGAN T。 USMC SGT
〃Oh； no；〃 Schofield said aloud。
〃What？〃 Renshaw said。 〃What is it？〃
Montana； Schofield thought。 Montana's real name was Morgan Lee。 Morgan T。 Lee。 Schofield looked up in horror。 Montana was ICG。
Down in the hangar； Gant and the others were searching for information about the black plane。
In a small workshop； Santa Cruz was looking at some schematics。 Sarah Hensleigh was sitting at a desk behind him； with a pencil and paper out。
〃Nice name；〃 Cruz said； breaking the silence。
〃What？〃 Sarah said。
〃The name of the plane。 Says here that they called it the Silhouette；〃 Santa Cruz said。 〃Not bad。〃
Sarah nodded。 〃Hmmm。〃
〃Any luck with that code？〃 he asked。
〃I think I'm getting closer；〃 Hensleigh said 〃The number that we were given； 24157817； seems to be a series of prime numbers： 2；41；5；7； until you get to 817。 But 817 is divisible by 19 and 43； which are also prime numbers。 But then； again； 817 could be two numbers； 81 and 7； or maybe even three numbers。 That's the hard part； figuring out just how many numbers 24157817 is supposed to represent〃
He smiled。 〃Better you than me； ma'am。〃
〃Thanks。〃
At mat moment； Montana came into the workshop。 〃Dr。 Hensleigh？〃 he said。
〃Yes。〃
〃Fox said to tell you that you might like to have a look at something she's found over in the office。 She said it was a codebook or something。〃
〃All right。〃 Hensleigh got up and left the workshop。
Montana and Santa Cruz were alone。
Santa Cruz resumed his examination of the ship's schematics。
He said； 〃You know； sir； this plane is something else。 It's got a standard turbofan power plant with supercruise capability。 And it's got eight small； retro jets on its underbelly for vertical takeoff and landing。 But the strange thing is； both of these power plants run on regular jet fuel。〃
〃So？〃 Montana said from the doorway。
〃So 。。。 what does the plutonium core do？〃 Santa Cruz said； turning to face him。
Before Montana could reply； Cruz turned back around to face his schematics。 He pulled some handwritten notes out from under them。
〃But I think I figured it out；〃
