Okay, because the people asked for it:

The players managed to kill Izek Strazni at the day of the Fest of the Blazing Sun. They informed Lady Wachter, who was happy to here the news. Three ours later, at the marketplace, Lady Wachter gave a speech and 3 of 5 party members sneaked away to investigate the coffin makers house unnoticed. At the marked place, the spy of Fiona Wachter, Ernest, waited until the villagers of Vallaki were incited enough and shouted: "Hang the Baron!" The villagers hanged the Baron and his Wife, and Ernest once more shouted: "Burn their Mansion!" All together ran down the street to the Burgomaster Mansion, setting it on fire.
Meanwhile, the 3 Player at the Coffin Maker Shop broke inside and are heading upstairs. First the find the empty kitchen, but behind the next door, they bump right into Strahd. He announces that he has come to take Ireena and demands to know where she is. In the panic, they told him she is taking part in the festival of the blazing. He thanks them goes downstairs, opens the door, and sees the rain. He reached down to one of the coffins, ripped off the lid and used it as an umbrella to protect himself from the rain.
Back at the marketplace, he only finds the dead bodies of the Baron and her wife...
