Picking up the doughnuts from the patisserie

1. During the conversation with Ligia, you can mention your favourite type of doughnuts, but this doesn't affect the quest in any way.
2. For the doughnuts, you need to travel to Northern Srodmiescie and visit the patisserie in its eastern part. To get the package, talk to Jagoda.

Waiting for the lecture

Meeting with members of Flying University

Solving the case of the missing book

2. Return to the book vendor and ask him about found coats - you'll unlock Waldemar observation and Who is the Thief? conclusion.

You'll unlock Waldemar's Testimony observation and receive a new objective to follow Waldemar's thoughts. The red trail will lead the hero to the bed shown in the screenshot above.
2. The book is here - you'll unlock What Was Lost Has Been Found observation. There is a letter attached to the book - check its contents. You'll unlock Note Hidden in the Volume observation and Lost Volume conclusion.

Returning the book

1. Once again, return to the book vendor. Thanks to obtained evidence, Wiktor can accuse 2 characters - Waldemar for stealing the volume and Cecylia for persuading him to do that.
