Dr. Sanders watched him stride off, head and shoulders held stiffly with a fierce self-sufficient pride, the slim hands behind his back twisting and fretting like nervous serpents.

Later that day, as he and Louise Peret had dinner together in the deserted hotel, Dr. Sanders said: "I don't know what the good Father's motives are, but I'm certain his bishop wouldn't approve of them."

"You think he may have-changed sides?" Louise asked.

Laughing at this, Sanders replied: "That may be putting it too strongly, but I suspect that, professionally speaking, he was trying to confirm his doubts rather than allay them. That cross in the market drove him into a frenzy-he was literally trying to shake it to death."

"But why? I've seen those native carvings, they're beautiful but just ordinary pieces of jewelry."

"No, Louise. That's the point. As Balthus knew, they're not ordinary by any means. There's something about the light they give out-I didn't get a chance to examine one closely-but it seems to come from inside them, not from the sun. A hard, intense light, you can see it all over Port Matarre."

"I know." Louise's hand strayed to the sunglasses that lay beside her plate, safely within reach like some potent talisman. At intervals she automatically opened and closed them. "When you first arrive here everything seems dark, but then you look at the forest and see the stars burning in the leaves." She tapped the glasses. "That's why I wear these, Doctor."

"Is it?" Sanders picked up the glasses and held them in the air. One of the largest pairs he had seen, their frames were almost three inches deep. "Where did you get them? They're huge, Louise, they divide your face into two halves."

Louise shrugged. She lit a cigarette with a nervous flourish. "It's March 21, Doctor, the day of the equinox."

"The equinox? Yes, of course-when the sun crosses the equator, and day and night are the same length-" Sanders pondered this. These divisions into dark and light seemed everywhere around them in Port Matarre, in the contrasts between Ventress's white suit and Balthus's dark soutane, in the white arcades with their shadowed in-fills, and even in his thoughts of Suzanne Clair, the somber twin of the young woman watching him across the table with her frank eyes.

"At least you can choose, Doctor, that's one thing. Nothing is blurred or gray now." She leaned forward. "Why did you come to Port Matarre? These friends, are you really looking for them?"

Sanders turned away from her level gaze. "It's too difficult to explain, I-" He debated whether to confide in her, and then with an effort pulled himself together. Sitting up, he touched her hand. "Look, tomorrow we must try to hire a car or a boat. If we share expenses it will give us longer in Mont Royal."

"I'll gladly come with you. But do you think it's safe?"

"For the time being. Whatever the police think, I'm sure it's not a virus growth." He felt the emerald in the gilt ring on Louise's finger, and added: "In a small way I'm something of an expert in these matters."

Without moving her hand from his touch, Louise said quietly: "I'm sure you are, Doctor. I spoke briefly this afternoon to the steward on the steamer." She added: "My aunt's cook is now a patient at your _léproserie_."

Sanders hesitated. "Louise, it's not my _léproserie_. Don't think I'm committed to it. As you say, perhaps we have a firm choice now."

They had finished their coffee. Sanders stood up and took Louise's arm. Perhaps because of her resemblance to Suzanne, he seemed to understand her movements as her hips and shoulders touching his own, as if familiar intimacies were already beginning to repeat themselves. Louise avoided his eyes, but her body remained close to him as they moved between the tables.

They walked out into the empty lobby. The desk clerk sat asleep with his head leaning against the small switchboard. To their left the brass rails of the staircase shone in the damp light, the limp fronds of the potted palms trailing onto the worn marble steps. Still holding Louise's arm, and feeling her fingers take his hand, Sanders glanced out through the entrance. In the shadows of the arcade he caught a glimpse of the shoes and trousers of a man leaning against a column.

"It's too late to go out," Louise said.

Sanders looked down at her, aware that for once all the inertia of sexual conventions, and his own reluctance to involve himself intimately with others, had slipped away. In addition he felt that the past day at Port Matarre, the ambivalent atmosphere of the deserted town, in some way placed them at a pivotal point below the dark and white shadows of the equinox. At these moments of balance any act was possible.

As they reached his door Louise drew her hand away and stepped forward into the darkened room. Sanders followed her and closed the door. Louise turned toward him, the pale light from the neon sign below illuminating one side of her face and mouth. Knocking her glasses to the floor as their hands brushed, Sanders held her in his arms, freeing himself for the moment from Suzanne Clair and the dark image of her face that floated like a dim lantern before his eyes.

Shortly after midnight, as Sanders lay asleep across the pillow on his bed, he woke to feel Louise touch his shoulder.

"Louise-?" He reached up and put his arm around her waist, but she disengaged his hand. "What is it-?"

"The window. Go to the window and look up to the southeast."

"What-?" Sanders gazed at her serious face, beckoning him across the room in the moonlight. "Of course, Louise-"

She waited by the bed as he crossed the faded carpet and unlatched the mosquito doors. Peering upward, he stared into the star-filled sky. In front of him, at an elevation of forty-five degrees, he picked out the constellations Taurus and Orion. Passing them was a star of immense magnitude, a huge corona of light borne in front of it and eclipsing the smaller stars in its path. At first Sanders failed to recognize this as the Echo satellite. Its luminosity had increased by at least tenfold, transforming the thin pinpoint of light that had burrowed across the night sky for so many faithful years into a brilliant luminary outshone only by the moon. All over Africa, from the Liberian coast to the shores of the Red Sea, it would now be visible, a vast aerial lantern fired by the same light he had seen in the jeweled flowers that afternoon.

Thinking lamely that perhaps the balloon might be breaking up, forming a cloud of aluminum like a gigantic mirror, Dr. Sanders watched the satellite setting in the southeast. As it faded, the dark canopy of the jungle flickered with a million points of light. Beside him Louise's white body glittered in a sheath of diamonds, the black surface of the river below spangled like the back of a sleeping snake.
