I see. Thanks!
This is the final conversation between Dijkstra and Philippa in Lady of the Lake. (I am reading the fans translation)
‘The half-elf who murdered the king,’ Dijkstra lowered his voice even more, ‘was definitely crazy. But he was not alone.’
‘What are you saying?’
‘Quiet,’ hissed Dijkstra. ‘Hush, Phil.’
‘Do not call me Phil. Do you have evidence? What? From where?’
‘You’d be surprised, Phil, if I told you where. When can I expect an audience with Your Ladyship?’
Philippa Eilhart’s eyes were like two black bottomless lakes.
‘Soon, Dijkstra.’
Bells rang. The crowd cheered hoarsely. The troops marched. The petals of flowers fell like snowflakes on the pavement of Novigrad.
After this, Dijkstra had to flee the northern kingdoms and became a fugitive with assassins on his trail, because he "said the wrong word to the wrong person". This implies Philippa was in on the assassination of Vizimir. And I find this unconvincing.
Firstly, what was her motive in killing Vizimir and supporting the Nilfgaard invasion ? I suppose the Lodge knows nothing about this, perhaps only Philippa and Vilgefortz. Vilgefortz was trying to gain Emhyr's trust I understand. But Why did Vilgefortz need Philippa's involvement ? (I suppose she could break his magic shield ?). Also weren't they on opposite side at the Thanedd coup ?
Secondly, even if she was guilty of regicide, why did she need to order a hit on Dijkstra ?
She already has a scapegoat, Vilgefortz, who was dead, Schirru was also dead, how can this be traced back to her ?
Furthermore, she's supposed to be a powerful sorceress, if she wanted to kill him why couldn't she do so during their secret meeting ? why hired assassins and made the whole thing much less certain ?
Perhaps I am misunderstanding something ...
