Philo Vance - The Left Handed Murder Case

Helen is awakened by her daughter Jan's scream, and runs to her room. Helen says "What happened? Did you have a bad dream?" Jan says "No, Mother. I saw Steve at my bedroom window. I haven't been able to sleep since we broke up, and I saw his face in the window". Helen says "I will call the police. Even if you were married to him, he had no right to do this". Jan says " the police will probably think I was dreaming, and he will deny that he was here. The police have been trying to get something on him for months, you know that". Helen says "We will talk about it in the morning. Your father has not returned from his meeting yet, I will leave him a message and stay in here with you tonight". The next morning, Helen is talking to Jan's father, David. She says "What are we going to do?". David says "I don't know, but I'm going to do something to make sure Steve doesn't bother Jan again".
