As he tries to revive her, he hears a shout for help, then gunshots and when he goes to investigate, the woman drives away in his car. He is soon able to trace her to nearby Greystone Manor and when he goes there to meet her she introduces herself as Phyllis Clavering and urges him to help her get out of a desperate situation.
