There is a kerfuffle in the conservatory. A purse has been stolen from a handbag. Steffi Braun saw only the hands of the thief that took her purse. But that may be all the evidence that Holmes needs.

Holmes: Your purse was stolen? Please tell me more.

Steffi: It was in my handbag by my chair when I was taking tea in the conservatory. There must have been someone behind the curtain by the window. I just saw her hands that's all. And of course, there is this earring that she dropped.

Holmes: So you saw both hands? Tell me, was she wearing a wrist watch?

Steffi: No, she wasn't.

Holmes: Watson, did you know that generally only people over 25 wear wrist watches?!

Watson: Well bless me Holmes. How do young people tell the time?

Holmes: They don't Watson. That's why they are always late. Come on. Let's go and arrest the young thief.
