"It's not too late to change plans and take the Subsea Tube to Naples," I said. "I have a negative vibration when it comes to rocket flights; why not go underground, the way the Lord intended us to travel?"

"I won the deck-cut, old boy," Felix said. "For myself, I've had enough of the underground life; I want a fast transit to New York."

"I feel a little exposed right now," I said. "Too bad we don't have two OE suits."

"Wouldn't help if we did; you couldn't wear one aboard an aircraft, tube, or anything else without showing up on a dozen different monkey-business detectors. But we'll be all right. They aren't looking for me-and your own mistress wouldn't know you now. You're good-looking, boy!"

"I know; I'm just talking to keep myself occupied."

"You have our prize exhibit all cozy in your trick belt?"

"Yep."

We drove in silence for the next mile. The city lights glowed on our right as we swung off on the port road. We pulled into a mile-wide lot under banked poly-arcs, then rode a slipway to the rotunda-a glass-walled arena under a paper-thin airfoil, cantilevered out in hundred-yard wings from supporting columns of ferro-concrete twelve feet thick at the base. I concentrated on walking without hopping, while Felix led the way across to an island of brighter lights and polished counters, where showgirls in trim uniforms stamped tickets and gave discouraging answers to male passengers with three-hour layovers to kill.

I watched the crowd while he went through the formalities. There were the usual fat ladies in paint and finger rings; slim, haughty women with strange-looking hats; bald businessmen with wilting linen and a mild glow expensively acquired at the airport bar; damp-looking recruits in rumpled uniforms; thin official travelers with dark suits, narrow shoulders, and faces as expressive as filing cabinets.

Once I spotted a big black and tan German shepherd on a leash, and I twitched; my foot hit a parked suitcase, sent it cannonballing against the counter. Felix stepped in quickly, soothed the fat man who owned the mishandled luggage, and guided me toward a glass stairway that swept up to a gallery lined with live-looking palms. We headed for a pair of frosted glass doors under three-foot glare-letters reading Aloha Room in flowing script.

"We have nearly an hour before takeoff; time for a light snack and a stirrup cup." Felix seemed to be in the best of spirits now; the fresh air had revived me, too. The sight of the normally milling crowds, the air of business-like bustle, the bright lights made the memories of stealthy horrors seem remote.

We took a table near the far side of the wide, mosaic-floored, softly-lit room. A smiling waitress in leis and a grass skirt took orders for martinis. Across the room, a group of dark, bowlegged men with flamboyant shirts and large smiles strummed guitars.

Felix glanced around contentedly. "I think perhaps we've overestimated the opposition, John." He lit up a dope-stick, blew violet smoke toward an ice-bucket by the next table. "Another advantage of rocket travel is the champagne," he remarked. "We can be nicely oiled by the time we fire retros over Kennedy-"

"While we're overestimating the enemy, let's not forget that he has a number of clever tricks we haven't quite mastered yet," I put in. "Getting out of Tamboula is a start, but we still have the problem of contact when we reach the States. We won't accomplish much hiding out in back rooms over tamale joints, sneaking out at night for a pictonews to find out what's going on."

Felix nodded. "I have some ideas on that score. We'll also need a quick and inconspicuous method of identifying 'human' aliens. I think I know how that can be done. We can work with the radar albedo of the alien skin, for example; it must be a rather unusual material to withstand puncturing steel doors."

He was smiling again, looking happy. He leaned toward me, talking against a strident voice from the next table.

"I've been working for twenty years, preparing for what I've termed a 'surreptitious war,' based on the premise that when the next conflict took place, it would be fought not on battlefields, or in space, but in the streets and offices of apparently peaceful cities-a war of brainwashing techniques, infiltration, subversion, betrayal. It's been in the air for a hundred years: a vast insanity that's kept us flogging away, nation against nation, race against race-with the planets at our fingertips…"

Something was happening. The music was changing to a sour whine in my ears. The chatter at the tables around me was like the petulant cries of trapped monkeys in vast, bleak cages.

Felix was still talking, jabbing with a silver spoon to emphasize his points. My eyes went to the double doors fifty yards distant across the brittle-patterned floor. Beyond the dark glass, shapes moved restlessly, like dim shadows of crawling men…

I pushed my chair back. "Felix!" I croaked.

"… could have established a permanent colony of perhaps five thousand. Carefully picked personnel, of course-"

"The door!" My voice was choking off in my throat. The air in the room seemed to darken; tiny points of light danced before me.

"Something wrong, old boy?" Felix was leaning forward, a concerned expression on his face. He looked as unreal now as a paper cutout-a cardboard man in a cardboard scene.

Far across the room, the doors swung silently open. A staring corpse-pale face appeared, at the level of a man's belt. It pushed into the room, the long, lean bristled body pacing on legs like the arms of apes, the fingered feet slapping the floor in a deliberate rhythm. A second beast followed, smaller, with a blacker coat and a grayish ruff edging the long-toothed face. A third and fourth passed through the door, both rangy, heavy, their long bodies sagging between humped shoulders and lean flanks. The leader raised his head, seeming to sniff the air.

"Felix!" I pointed.

He turned casually, let his gaze linger a moment, then glanced at me with a slight smile.

"Very attractive," he said. "You must be recovering, John, for a pretty face to excite you-"

"Good God, Felix! Can't you see them?"

He frowned. "You're shouting, John. Yes, I saw them." I was aware of faces turning toward me at the surrounding tables, eyebrows raised, frowns settling into place. I reached out, caught Felix's arm; his face contorted in a spasm of agony.

"Felix-you've got to listen. What do you see coming through that door?"

"Four young women," he said in a choked voice, "very gay, very sweet. Would that I had time…" His face was paling. "John, you're breaking my arm-"

I jerked my hand back. "They're aliens, Felix! The dog things I saw in the ravine! Look again! Try to see them!"

The leading demon had turned toward us now; the white face was fixed on me as it came on, steadily, relentlessly, stalking unnoticed along the aisle between the tables where diners laughed and talked, forking food into overfed mouths.

Felix turned, stared. "They're coming toward us," he said in a voice thin with strain. "The first young lady is dressed in yellow-"

"It's a thing like a tailless dog; a skull-face, stiff black hair. Remember the ear?"

Felix tensed; an uncertain expression crept over his face. He turned toward me.

"I-" he started. His features went slack; his head lolled, eyes half-open. The music died with a squawk. Conversation drained into silence.

The first of the monstrosities quickened its pace; its head came up as it headed straight for me. I leaned toward Felix, shouted his name. He muttered something, slumped back, stared vacantly past me.

"Felix, for God's sake, use your gun!" I jumped up, and my knee caught the table; it went flying against the next one. Felix tumbled back, slammed to the floor. I caught a momentary impression of dull-faced patrons, sitting slackly at tables all around. There was a quickening slap of beast-hands now as the leading thing broke into a clumsy gallop, closing now, red eyes glinting, the black tongue lolling from the side of the wide jaws as it cleared the last few yards, sprang.
