Blaine Malcomess was oblivious of all else as he followed the prime minister's speech. Shasa saw the messenger reach him and hand him the note.

Shasa looked back at the gallery and Tara was still concentrated on her father. After all the years Shasa could read her expression, and he had never seen her so worried and concerned, even when one of the children was gravely ill.

Then her face cleared with patent relief and Shasa glanced back at Blaine. He had unfolded the note and was reading it. Suddenly Blaine leapt to his feet and hurried towards the main doors.

Tara had summoned her father - that much was obvious. Shasa stared at her, trying to divine her purpose. Almost as though she sensed his gaze, Tara looked directly at him, and her relief crumbled into horror and wild guilt. She turned and fled from the visitors' gallery, pushing aside those who stood in her way.

A second longer Shasa stared after her. Tara had enticed her father out of the chamber, and her concern could only have been so intense had she believed he was in some kind of dire danger. This was followed by guilt and horror as she realized that Shasa was watching her. It was clear to Shasa then that something terrible was about to happen. Moses Gama and Tara - there was danger, mortal danger and Tara was trying to save her father. The danger was pressing and imminent - the wires in his office, the chest, Blaine and Tara and Moses Gama. He knew they were all interwoven and that he had little time in which to act.

Shasa jumped to his feet and strode down the aisle. Verwoerd frowned and checked his speech, watching him, while all around the chamber heads turned. Shasa quickened his stride. Manfred De La Rey reached out to touch him as he passed his bench, but without a glance at him Shasa brushed past his outstretched hand and went on.

As he hurried out into the lobby Shasa saw Blaine Malcomess near the front door talking agitatedly to the janitor. As soon as he saw Shasa he said, 'Thank God!" and came towards him across the chequered marble floor.

Shasa turned away from him and looked up the staircase. From the top Tara stared down at him, white-faced and terrified, held by some unnatural passion.

'Tara!" Shasa called and started towards the foot of the staircase, but she whirled and disappeared around the angle of the corridor.

Shasa flew at the stairs, taking them three at a time.

'What's happening, Shasa?" Blaine called after him, but Shasa did not answer.

He came out of the staircase still at a run, and as he rounded the corner Tara was halfway down the corridor ahead of him. He did not waste time by shouting at her, and instead flung himself forward, and sprinted after her. As she ran, Tara glanced over her shoulder and saw him swiftly overtaking her.

'Moses!" she screamed. 'Look out, Moses!" It was futile, the panelled walls of Shasa's office were too thick and soundproof for her warning to reach him, and her cry confirmed all Shasa's worst suspicions.

Instead of running straight on towards the front door of his suite as Shasa expected, Tara jinked suddenly into the side passage, ducking under Shasa's outstretched arm and he tried to turn with her but he was off balance as she disappeared into his blind spot.

Shasa ran into the corner of the wall, crashing into it head-first, taking it on the brow above his blind eye. The silk patch cushioned the impact slightly, but still the skin split and blood poured down his cheek. Although he was stunned, Shasa managed to keep his feet.

He staggered in a full circle, still dazed. Blaine was following him, his face flushed with effort and concern as he ran down the corridor.

What the hell is going on, Shasa?" he roared.

Shasa turned from him, and saw Tara at the door to the back entrance of his office. She had a key, but she was in such a state that her hands were shaking too wildly to insert it in the lock.

Shasa gathered himself, shaking the darkness out of his head, and the droplets of his blood splattered the wall beside him. Then he launched himself after Tara. She saw him coming and dropped the key, it tinkled at her feet, and she clenched her fists and beat with them on the closed door.

'Moses!" she screamed. 'Moses!" As Shasa reached her the door was jerked open from the inside, and Moses Gama stood in the threshold. The two men confronted each other over Tara's head until Tara ran forward.

Moses, I tried to warn you,' she screamed and threw both arms around him.

In that instant Shasa looked beyond the pair and saw that the altar chest stood open, its contents piled on the carpet. The coil of wire that he had found behind the encyclopaedias had been laid across the floor to his desk and connected to some kind of compact electrical apparatus. Shasa had never seen one before, but he knew instinctively that it was a detonation device and that it was ready to fire. On the desk top beside it lay an automatic pistol.

As a firearms enthusiast and collector, he recognized it as a Tokarev 7.62 men, the standard Russian military issue. On the floor behind his desk Tricia lay on her side. She was gagged and bound at wrists and ankles, but she was wriggling desperately and giving little muffled cries.

Shasa lunged forward to tackle Moses Gama, but the black man gathered Tara in his arms and hurled her into Shasa's chest. The two of them reeled backwards against the jamb of the door. Moses spun around and leapt to the desk, as Shasa tried to get free of Tara. She was clinging to him and moaning. 'No! No! He must do it." Shasa broke her grip and flung her aside, but across the room Moses was standing over the electrical transmitter. He pressed a switch and a bulb on the panel of the casing glared redly.

Shasa knew that he could not reach Moses across the floor before he fired the device, but his mind was racing ahead of his limbs and ( body. He saw the wire strung out across the carpet, almost at his feet, and he stooped and took a twist of it around his right hand and heaved back against it with all his strength.

The end of the wire was firmly attached to the transmitter, and as Shasa hauled on it the device was jerked out of Moses' hands and flew off the desk top to clatter across the floor, midway between the two of them.

They both leapt for it at the same instant, but Moses was by a fraction of a second the quickest, and his hands scrabbled on the transmitter. Shasa was in full stride, and he did not check. He leaned forward, and transferred all the weight and power of his body into his hips, swinging his right leg into the kick he aimed at Moses' head.

The kick caught Moses in the side of the temple, and snapped his head over. The transmitter tumbled from his grip and he was flung over backwards, rolling until he crashed into the desk.

Shasa followed him and aimed another flying kick at his head, but Moses caught his foot on his raised forearm and seized his ankle. He twisted violently, lifting the ankle and Shasa was caught on one foot with his weight backwards, and he fell heavily.

Moses pulled himself up the side of the desk and reached out for the Tokarev pistol, and Shasa scrambled after him on hands and knees. As Moses swung the pistol around, Shasa lunged at him again and grabbed his wrist with both hands. They wrestled over the floor, rolling and kicking and grunting, fighting for the Tokarev.

Tara had recovered and now she ran into the room and picked up the fallen transmitter. She stood helplessly with it in her hands.

'Moses, what must I do?" she cried.

Moses grunted with a supreme effort as he rolled on top of Shasa.

'The yellow button. Push the yellow button!" At that instant Blaine Malcomess ran in through the open door.

'Stop her, Blaine!" Shasa yelled. 'They are going to blow --' Moses' elbow hit him in the mouth and cut off the words.
