• Helen is already understandably frightened at having to sleep in the room where Julia died and to sleep in her sister's bed. But then when she hears the "low whistle" Julia told her about she becomes terrified. This whistling is what prompts her to travel to London early the next morning and consult Sherlock Holmes.
