Ventress walked across to Sanders, who was standing with his back to the wall beside the window.

"All right. He's gone."

Sanders hesitated before moving. He glanced around the trees at the edges of the lawn, trying not to expose more than a glimpse of himself. At the far end of the lawn, framed between two oaks, a white gazebo had been transformed by the frost into a huge crystal crown. Its glass casements winked like inlaid jewels, as if something were moving behind them. Ventress, however, stood openly in front of the window, surveying the scene below.

"Was that Thorensen?" Sanders asked.

"Of course." This brief passage-at-arms seemed to have relaxed Ventress. The shotgun cradled loosely in his elbow, he strolled around the room, now and then pausing to examine the puncture left by the bullet in the ceiling. For some reason he obviously assumed that Sanders had taken his side in this private duel, perhaps because Sanders had already saved him from the attack in the native harbor at Port Matarre. Sanders's actions, however, had been little more than reflex, as Ventress no doubt was aware. Patently Ventress was not a man who ever felt under much obligation to other people, whatever they might have done for him, and Sanders guessed that in fact Ventress had sensed some spark of kinship during their voyage by steamer from Libreville and that he would plunge his entire sympathy or hostility upon such a chance encounter.

The movement inside the gazebo had ended. Sanders stepped forward from his hiding place behind the window.

"The attack on you in Port Matarre-were those Thorensen's men?"

Ventress shrugged. "You might well be right, Doctor. Don't worry, I'll look after you."

"You'll have your work cut out-those thugs meant business. From what the army captain at the base told me the diamond companies don't intend to let anything get in their way."

Ventress shook his head, exasperated by Sanders's obtuseness. "Doctor! You persist in finding the most trivial reasons-obviously you have no idea of your real motives! For the last time, I am not interested in Thorensen's damned diamonds-and nor is Thorensen! The matter between us-" He broke off, staring vaguely through the window, his face for the first time showing any sign of fatigue. In a distracted voice, more to himself, he went on: "Believe me, I respect Thorensen- however crude, he understands that we have the same aim, it's a question of method-" Ventress swung on his heel. "We'd better leave now," he announced. "There's no point in staying. Where are you going?"

" Mont Royal, if that's possible."

"It won't be." Ventress pointed through the window. "The storm center is directly between here and the town. Your only hope is to reach the river and follow it back to the army base. Whom are you looking for?"

"A former colleague of mine and his wife. Do you know the Bourbon Hotel? It's some distance from the town. Their mission hospital is near the hotel."

"Bourbon?" Ventress screwed up his face. "Sounds like the wrong century-you're out of time again, Sanders." He made for the door. "It's an old ruin, God only knows where. You'll have to stay with me until we reach the edge of the forest, then work your way back to the army base."

Testing each step, they went down the crystallizing staircase. Halfway down, Ventress, who was in the lead, stopped and beckoned Sanders forward.

"My pistol." He patted his shoulder holster. "I'll follow you. See if you notice anything from the door."

As he retraced his steps. Sanders walked across the empty hail. He paused among the jeweled pillars, uneager, whatever Ventress's instructions, to expose himself in the wide doorway with its colonnaded portico. From the center of the hail the garden and trees beyond were silent, and he turned and waited among the pillars by the alcove on his left, dozens of reflections of himself glowing in the glass-sheathed walls and furniture.

Involuntarily Sanders raised his hands to catch the rainbows of light that ran around the edges of his suit and face. A legion of El Dorados, all bearing his own features, receded in the mirrors, more images of himself as the man of light than he could have hoped for. He studied a reflection of himself in profile, noticing how the bands of color softened the drawn lines of his mouth and eyes, blurring the residue of time there that had hardened the tissues like the scales of leprosy itself. For a moment he seemed twenty years younger, the ruddy overlay of colors on his cheeks more skilful than the palette of any Rubens or Titian.

Turning his attention to the reflection facing his own, Sanders noticed with surprise that among these prismatic images of himself refracted from the sun he had found one darker twin. The profile and features were obscured, but the skin was almost ebony in color, reflecting the mottled blues and violets of the opposite end of the spectrum. Somehow menacing in this company of light, the somber figure stood motionlessly with its head turned away from him, as if aware of its negative aspect. In its lowered hand a lance of silver light flared like a star in a chalice.

Abruptly Sanders leapt behind the pillar on his left, as the Negro hiding in the alcove lunged forward across him. The knife flashed in the air past Sanders's face, its white light diving among the reflections that swerved like drunken suns around the two men, the colors bleeding off their arms and legs. Sanders kicked at the Negro's hand, half-recognizing one of the thugs he had seen on the catwalk at Port Matarre. Crouching down, his bony pointed face almost between his knees, the Negro feinted with the knife. Sanders moved back toward the staircase, and then saw the giant mulatto in the bush-shirt watching from behind a bookcase in the drawing room, a Colt automatic in his scarred hand. The frost outside had given his dark face a luminous sheen.

Before Sanders could shout up to Ventress, a shot roared out through the air over his head. Ducking down, he saw the Negro with the knife knocked to the floor, his heels kicking in pain. The punctured lattice on the wall behind him slid and shattered across a divan, and the Negro picked himself up and raced like a wounded animal through the entrance. A second shot followed him from the staircase, and Ventress moved down from his vantage point behind the banister. His tight face hidden behind the stock of the shotgun, he beckoned Sanders away from the entrance to the drawing room. The mulatto hiding by the bookcase ran across the room, firing once as he stopped below the chandelier, the impact of the explosion showering the light from the cutglass pendants like rain over his cropped head. He shouted at a tall white-skinned man in a leather jerkin who stood by the far wall, with his back to the staircase opening a safe over the ornamental fireplace.

Covering him, the mulatto fired through the door. The man by the safe dragged a small strongbox from the upper shelf as Ventress upended the mahogany hall stand across the archway. The strongbox fell to the floor, and dozens of rubies and sapphires scattered between the tall man's feet. Ignoring Ventress, who was trying to get in a shot at the mulatto, he bent down and scooped some of the stones into his big hands. Then he and the mulatto turned and ran for the French windows, crushing aside the light frames with their shoulders.

Leaping over his barricade, Ventress entered the drawing room, darting in and out of the overstuffed settees and armchairs. As his quarry disappeared through the trees Ventress reached the windows, then reloaded his gun with the shells in his pocket and fired a parting shot over the lawn.

He moved the barrel in Sanders's direction as the latter stepped over the hall stand into the room.

"Right, Doctor, all clear?" Ventress was breathing rapidly, his small shoulders moving about in an excess of nervous energy. "What's the matter? He didn't touch you, did he?"
