Death of a Patron

The Rabbinate of the Prague Jewish Community is holding a two-day Sabbath celebration for its members and other interested parties. After the event, two dead bodies are found in the rented wellness centre where the Sabbath was held. One belongs to Alois Sváček, the building's elderly maintenance man. The other is Kamil Novák, a wealthy businessman who is a generous sponsor of the Rabbinate. Both were killed with a knife. What role does the beautiful cleaner from the wellness centre play in the case? And who exactly is this patron, in whose villa Jewish ritual objects are found?
