"It's all right—it's only a sleep dart," Kuryakin said. "Now...move away from that laser and put your hands up, quick!"

The girl moved like lightning. Spinning the three big barrels to put a different one in the place between the two ends of the equipment, she swung the whole apparatus around on the tripod so that the business end was pointing into the room.

"Down!" Illya yelled, hurling himself to the floor as the invisible beam swept over his head. Solo dropped like a stone and rolled under one of the benches.

There was a brilliant blue flash as the revolving equipment came to a halt and the beam stayed on the big transmitter. Smoke poured from the bench and he radio chassis, the plaster on the wall crumbled, and an instant later the whole side of the room was a mass of flame as the wooden laths behind caught fire.

Helga Grossbreitner leaped over Illya's prone figure, dodged around the beam and ran for the door. As Kuryakin took a shot at her and missed, he saw in the light of the flames a small alcove to one side of the door. On a wheeled operating table in the recess, lashed to the chromium rails of the trolley and gagged with insulating tape, lay the almost naked unconscious figure of Sheridan Rogers.

"Sherry!" Illya shouted. "Get her out of here, Napoleon. I'll look after the woman..." He struggled to his feet, bent double to run under the laser beam and made for the doorway through which Helga had vanished.

Before he was halfway across the room, there was a low rumbling and armored steel shutters dropped heavily down to seal off both door and window.

Chapter 15 — All the fun of the fair

Illya launched himself at the doorway and beat upon the smooth metal curtain—but the armored shutter ran tightly in steel channels and would not move. Behind him, Solo ran the wheeled operating table out of the alcove and away from the flames, wrestling with the thin cords binding Sherry Rogers to the frame. The fierce flare of light emphasized the hollows of her supple body, sculpturing the contours.

Choking in the smoke which was now filling the room, Kuryakin was back at the laser. Throwing off the master switch, he wheeled the apparatus around to point at the steel-curtained door. "If the barrel in position is a ruby rod laser," he gasped, "it should be able to cut through that shutter—providing it's not more than three-eighths of an inch thick...Stand back, Napoleon: we'll have a go!"

He flicked the switch back to the 'on' position. Immediately, there was a blinding flash of crimson light and a shower of sparks from the metal surface walling them in. In less than a second, the concentrated energy of the laser beam had punched a hole in the steel. Shepherding the long barrels up and around by means of the control wheel, Illya slowly carved with the beam an irregular circle about two feet in diameter. In the confined space, the heat of the blazing wall, the roar of the flames and the acrid attack of the smoke were almost unbearable. The two agents were bathed in sweat by the time Kuryakin had completed the circle and the roundel of steel inside it fell outwards with a dull clang.

"You go after her, Illya," Solo yelled. "I'll get these birds out of here if I can and join you later." As Kuryakin dived head first through the ragged hole in the shutter, he was dragging the unconscious figures of Celeste and Sherry towards the door.

On the landing, Illya paused to drag a few gulps of cold air deep into his tortured lungs. Which way had Helga Grossbreitner gone? Up or down?

For a second, he paused, irresolute. Then a faint draft from the open trapdoor in the ceiling decided him. He sprang for the ladder and climbed rapidly to the attics.

Wisps of smoke curled from the landing walls and the wooden floor of the rooms under the roof was already ablaze. Lifting his feet high to avoid the flames, the Russian dashed past the figure of Larsen, still slumped in the chair where they had left him, and jumped onto the steel gray console Solo had seen from the roof. Above his head, the skylight yawned open to the sky.

Reaching up, Illya grasped the edge and hauled himself to the tiles.

Helga Grossbreitner was three roofs away, poised on the edge of a six-foot gap where an alley ran between two houses. She was wearing knee-high boots, skin-tight black leather pants and a white shirt—and her ripe figure was silhouetted against a strange orange glow which suffused the sky beyond the far end of the village.

As Illya hastened crabwise after her across the tiled slopes, dodging chimney stacks and television aerials and water tanks, the glow deepened to scarlet and then began to flicker as great clouds of smoke bellied across the skyline. The fireworks display was over and the symbolic reconstruction of the sacking of St. Paul by the Saracens had begun.

The girl hesitated a moment longer and then gathered herself and jumped the gap. She landed awkwardly; lost her footing, fell, and slid almost to the guttering before her desperately scrabbling hands found enough leverage among the curved tiles to arrest her progress.

Catfooted, the Russian raced across the roofs to close the gap between them. The girl must have heard his hurrying footsteps as she struggled to her feet, for she paused, looked back over her shoulder, and then raised her right arm in his direction. An orange flower bloomed suddenly from her hand. Illya ducked back behind a chimney, listening to the simultaneous crack of the explosion and the shrill whine of the bullet as it hit a coping and ricocheted away into the night.

After a second, he peered cautiously around the brickwork. Helga was just disappearing over the edge of the roof onto a fire escape.

He set off again at a run, taking the space over the alleyway in his stride, almost losing his balance as he landed, and then, righting himself, dashing on to the far end of the roof and the fire escape. As he looked over, there was a flash and a crack from below. A bullet spanged off the iron staircase just below the level of the roof.

Having waited a moment, he raised his head and gazed over the parapet again. The sky over the rooftops was a deep crimson now; a menacing glare reflected fitfully from the dense clouds of smoke billowing from the ramparts. In the blood-red light he located Helga standing at the foot of the fire escape—and once more flames blossomed twice from the gun in her hand. He drew back, looked over again, and for the third time a bullet sent him scurrying back into cover like a tortoise into its shell. Obviously the girl was prepared to keep him tied down there.

His own gun, loaded with sleep darts, was useless at this range. He would have to try and outflank the girl. Worming his way back, he inched down to the guttering at the side of the house. The wall was covered with the branches of an ancient vine.

Groping about in the leaves until he found the main stem, he seized hold of the gnarled wood, swung his legs over the gutter, and began to lower himself, hand over hand, slowly to the ground four stories below. Dust, insects and small twigs showered upon his head and threatened to choke him as he descended, but at last his exploring toe discovered firm ground and he found himself in a small walled garden.

Skirting an ornamental pond, he pushed through a row of dwarf cypresses, stepped up onto a garden roller and straddled the six-foot wall. On the far side was a small cobbled square. The tight, shining hemispheres of Helga Grossbreitner's leather-clad rump were just disappearing through an archway opposite.

Illya looked back and up along the roofline of the houses he had just left. From the upper windows of the THRUSH headquarters, flames and smoke were streaming. As he watched, a shower of sparks burst through the skylight, and a moment later a column of fire exploded into the night and licked hungrily at the sky. He wondered if Solo had managed to get the women safely out of the burning building, shrugged, and dropped quietly to the ground.
