Ciri's Room
Grab this quest as you're doing part of the Bloody Baron, just after you've played as Ciri and investigated the Baron's wife's bedroom.
Inside Ciri's room you'll find a book that you should read, and then examine the spinning top, which will send you to see Gretka in the kitchen. Then go back into Ciri's room and check the clothes on the floor. Ciri left in a hurry... and that's it.
