Nemesis Reading #8

The woman who was injured, Mrs. Temple has asked to see Jane Marple at the hospital when she returns to conciousness. Proffessor Wanstead tells Jane more about the accident that had occured several days before. Joanna Crawford and Emlyn Price, two young people also on the tour, told the Proffesor that they had seen the silhouette of a person on a hill above Mrs. Temple that pushed the boulder to roll on top of her. Joanna said she could not identify if it was a man of a woman, but she did identify what they were wearing for clothing. I don't understand why they would come out and tell people days after the accident occured; it seems rather odd and suspicious to me.
