Poisoning at the Biarritz opera house
📄 Initial report (story and known facts)
📜 Story
The end-of-season party was in full swing at the Biarritz opera house. Victor Lebœuf, boss of the cannery and the opera's great patron, was due to make an announcement. He never had the time: he suddenly went pale in the artists' dressing rooms. Poisoning. The victim has been saved; the culprit is still at large, and several members of the troupe are lying about their evening.
🎯 Your goal: turn over all 40 cards in the 3 tabs (People, Places, Objects). A card only turns over if the clues prove it (no guessing allowed), and every card you turn over gives you a new clue.
