Ori Reuven
From Witcher Wiki
Oribasius Giafranco Paolo Reuven, the personal assistant of Sigismund Dijkstra, the head of the Redanian secret service. He wrote the book Shadow People, or the story of His Majesty's Secret Service.
Later, Ori was arrested and interrogated and he ultimately succumbed to old age in a temple hospice, his body wrecked by asthma, anaemia and glaucoma.
[edit] In The Witcher computer game
In the computer game, you can meet a bootblack in the alley outside Detective Raymond's place in the Temple Quarter. He is a good source of general information but you quickly notice that he seems rather well-informed for a bootblack. When you challenge him on this, he clams up and won't speak to you again until you have left the area completely and come back.
If you have previously engaged in a drinking contest with Thaler, you have a seemingly useless book, Shadow People, or the story of His Majesty's Secret Service. If you speak to the bootblack a second time, you'll notice that you now have the option to give him a gift. Give him the book.
At this point, he says "You know who I am... ahem, I thought that scroll had disappeared for good.", which confirms that he is in fact Ori Reuven. After a bit more conversation, he gives you The Prophet Lebioda's signet ring, which is rumoured to allow one to get past Grandma at Shani's place.
