Spanish style。 The smell of baking corn wafted through the pickup's open windows。
〃Diabolically clever disguise；〃 Zavala said。
〃I hardly expected to see a neon sign that said； 'Wele from the guys who killed the whales。' 〃
〃I wish we were toting our guns；〃 Zavala said with mock gravity。 〃You never know when a wild tortilla will attack you。 I once heard about someone being mauled by a burrito in No gales…〃
〃Save it for the drive back。〃 Austin got out of the car and led the way to the ornately carved front door of dark wood。
They stepped into a whitewashed reception area。 A smiling young Mexican woman greeted them from behind a desk。 〃Buenos dias；〃 she said。 〃You are in luck。 The tour of the tortilla factory is just starting。 You're not with a group from a cruise boat？〃
Austin suppressed a smile。 〃We're on our own。 We were driving by and saw the sign。〃
She smiled again and asked them to join a group of senior citizens； mostly Americans and mostly from the Midwest from the sounds of their accents。 The receptionist； who also acted as guide； ushered them into the bakery。
〃Corn was life in Mexico； and tortillas have been the staple food in Mexico for centuries with both the Indians and the Spanish settlers。〃 She led the way past where sacks of corn were being emptied into grinding machines。 〃For many years people made their tortillas at home。 The corn was ground into meal； mixed with water to produce masa； then rolled； cut； pressed； and baked by hand。 With the growth of demand in Mexico and especially in the United States； the tortilla industry has bee more centralized。 This has allowed us to modernize our production facilities providing for more efficient and sanitary operation。〃
Speaking in low tones as they trailed behind the others； Austin said； 〃If the market for Mexican flapjacks is in the U。S。； why isn't this place closer to the border？ Why make them down here and ship them up the highway？〃
〃Good question；〃 Zavala said。 〃The tortilla business in Mexico is a tightly held monopoly run by guys with close government connections。 It's a billion…dollar industry。 Even if you did have a good reason to locate this far south； why build overlooking the ocean？ Nice place for a luxury hotel； but an operation like this？〃
The tour went past the dough mixers which fed into machines that produced hundreds of tortillas a minute； the thin flat pies ing out on conveyor belts； all tended by workers in laundry…white coats and plastic caps。 The guide was ushering the group to the packaging and shipping department when Austin spied a door with words written in Spanish on it。 〃Employees only？〃 he asked Zavala。 Joe nodded。
〃I've learned all I want to know about burritos and enchiladas。〃 Austin stepped aside and tried the door。 It was unlocked。 〃I'm going to look around。〃
Eyeing Austin's imposing physique and blazing white hair； Zavala said； 〃With due respect for your talents as a snoop； you don't exactly blend in with the people working around here。 I might be less conspicuous than a giant gringo stalking the hall ways。〃
Zavala had a good point。 〃Okay； snoop away。 Be careful。 I'll meet you at the end of the tour。 If the guide asks； I'll say you had to go to the restroom。〃
Zavala winked and slipped through the door。 He was confident he could charm his way out of practically any situation and had already prepared a story saying he'd bee lost looking for the bano。 He found himself in a long hallway with no windows or other openings except for a steel door at the far end。 He walked the length of the hallway and put his ear against the door。 Not hearing anything； he tried the knob。 The door was locked。
He reached into his pocket and pulled out a modified Swiss Army knife that would have got him arrested in places where possession of burglar tools is illegal。 The standard attachments such as scissors； nail file； and can opener had been replaced with picks for the most mon locks。 On the fourth try he heard the latch click open。 Behind the door another corridor slanted down。 Unlike the first； this passage had several doors。 All were locked except one that opened into a locker room。
The lockers were secure； and he could have opened them with his picks if he had time。 He glanced at his watch。 The tour would wind up soon。 On the opposite wall were shelves piled with neatly folded white coats。 He found one that fit and slipped it on。 In a supply cabinet he discovered a clipboard。 He stepped out into the corridor and continued on to yet a third door。 This； too； was locked； but he managed to open it after a few tries。
The door opened onto an elevated platform that overlooked a big room。 The platform led to a series of walkways that crossed through a web of linking horizontal and vertical pipes。 The low hum of machinery seemed to e from everywhere； and he couldn't trace its source。 He descended a set of stairs。 The pipes came out of the floor； then disappeared at right angles into the wall。 Plumbing for the tortilla factory； he surmised。 At one end of the room was another door。 It was unlocked。 When he cautiously opened it； a cool ocean breeze hit him in the face。
He gasped with surprise。 He was standing on a small plat form perched high on the side of a cliff； facing out onto a lagoon about two hundred feet below him。 It was a beautiful vista； and again he wondered why somebody hadn't built a hotel rather than a factory there。 He assumed the factory was behind the edge of the cliff； but he couldn't see it from his angle。 He looked down again。 The water washed up against the jagged rocks along the shore in foamy ripples。 The platform had a gate at one end that led to empty space with no steps going down or up。 Odd。 A few feet from the gate a metal rail ran down the side of the cliff and disappeared into the water。
He followed the rail down to the lagoon with his eye。 A section of water appeared to be darker than that surrounding it。 It might have been kelp and other seaweed washing against the rocks。 As he watched； there was an intense bubbling at the base of the cliff； and a large； shiny； egg…shaped object suddenly appeared from the water and began its climb up the side of the cliff。 Of course！ The rail was for an elevator。 The egg rose steadily up the track。 It would be there within seconds。 Zavala ducked back into the big room with the pipes； keeping the door open a crack。
The egg； made of a dark tinted glass or plastic that blended in with the side of the cliff； came to a stop at the platform。 A door opened； and two men in white smocks stepped out。 Zavala dashed for the stairs。 Within seconds he was back at the store room。 He tore his coat off； folded it as neatly as possible； and quickly walked along the corridors to the bakery。 Nobody saw him step back into the area open to the public。 He hurried along in the direction Austin and the tour group had taken。 The guide saw him approach and gave him a quizzical and not altogether pleased look。 〃I was looking for the bano。〃
She blushed and said； 〃Oh； yes。 I will show you。〃 She clapped her hands for attention。 〃The tour is about over。〃 She handed everyone a sample package of tortillas and conducted them back to the reception area。 As the cars and tour buses left； Austin and Zavala pared notes。
〃From the look on your face I'd guess your little exploration was successful。〃
〃I found something。 I just don't know what it is。〃 Zavala laid out a quick summary of his findings。
〃The fact that they hid something underwater indicates that they don't want anyone to know what they are doing；〃 Austin said。 〃Let's take a walk。〃
They strolled around the side of the factory but only got a short distance toward the water before they encountered a high mesh fence topped with razor wire a few hundred feet short of where the cliff dropped off。
〃So much for an ocean view；〃 Zavala said。
〃Let's see if we can get around to the other side of the cove。〃
The two men returned to the pickup and drove back onto the road。 Several tracks led down to the sea； but the fence blocked each potential access。 They were just about to give up when they saw a man with a fishing pole and a basket full of fish ing from a path that led toward the water。 Zavala called him over and asked if they could get to the water。 The man was wary at first； apparently thinking they had something to do with the tortilla place。 When Zavala extracted a twenty…dollar bill from his wallet； the man's face lit up； and he said yes； there was a fence； but there was a place to crawl under it。
He led them on a narrow path through the shoulder…high bushes； pointed to a section of chain…link fence； and left clutching his windfall。 A section of fence was bent back from the ground and a hole scooped out underneath。 Zavala easily slithered under to the other side； then held the fence for Austin。 They followed the overgrown path until they came to the edge of a cliff。 They were near the tip of the southernmost promontory enclosing the lagoon。
A trail that must have been worn by the feet of fishermen descended down the less steep side of the point。 The NUMA men were more interested in t
