A Plea for help

The party is greeted by Ismark Kolyanovich in the Blood on the Vine tavern in Barovia. After a short conversation he tells the party that they can't discuss too much here and offers them his home for the night. The party declines and stays in the tavern for the night. Meeting with Ismark in the morning he informs the party of his troubles. Is father is recently deceased and he needs help transporting the coffin to the Barvoia gravesite. He fears that if he is too occupied with the transport his sister Ireena Kolyanovich is vulnerable. The lord of Barovia, Strahd von Zarovich has been very interested in her. Ismark is unsure why but he is sworn to protect his sister. 
He asks the party to transport the coffin with him to the graveyard so his father can receive a proper burial
