‘Why did Lydia have to die, Vilgefortz? Why did you order her death? She was meant to distract attention from you, wasn’t she? She was meant to give you time to become resistant to dimeritium, to send a telepathic signal to Rience, wasn’t she? Poor Lydia, the artist with the damaged face. Everyone knew she was expendable. Everyone knew that except her.’

‘Be silent.’

‘You murdered Lydia, wizard. You used her. And now you want to use Ciri? With my help? No. You will not enter Tor Lara.’

The sorcerer took a step back. Geralt tensed up, ready to jump and strike. Vilgefortz did not raise his hand, however, but simply held it out to one side. A stout, two-yard staff suddenly materialised in his hand.

‘I know,’ he said, ‘what hinders you from making a sensible assessment of the situation. I know what complicates and obstructs your attempts at making a correct prediction of the future. Your arrogance, Geralt. I will disabuse you of arrogance. And I will do so with the help of this magic staff here.’

The Witcher squinted and raised his blade a little.

‘I’m trembling with impatience.’

A few weeks later, having been healed by the dryads and the waters of Brokilon, Geralt wondered what mistakes he had made during the fight. And came to the conclusion he hadn’t made any. His only mistake was made before the fight. He ought to have fled before it even began.

The sorcerer was fast, his staff flickering in his hands like lightning. Geralt’s astonishment was even greater when, during a parry, the staff and sword clanged metallically. But there was no time for astonishment. Vilgefortz attacked, and the Witcher had to contort himself using body-swerves and pirouettes. He was afraid to parry. The bloody staff was made of iron; and magical to boot.

Four times, he found himself in a position from which he was able to counterattack and deliver a blow. Four times, he struck. To the temple, to the neck, under the arm, to the thigh. Each blow ought to have been fatal. But each one was parried.

No human could have parried blows like that. Geralt slowly began to understand. But it was already too late.

He didn’t see the blow that finally caught him. The impact drove him against the wall. He rebounded from it but was unable to jump aside or dodge. The blow had knocked the breath out of him. He was caught by a second blow, this time on the shoulder, and once again flew backwards, smashing his head against a protruding caryatid’s breast on one of the pilasters. Vilgefortz leapt closer, swung the staff and thumped him in the belly, below the ribs. Very hard. Geralt doubled up and was then hit on the side of the head. His knees suddenly went weak and crumpled beneath him. And the fight was over. In principle.
