A famous artist, Ms. Monet, is found dead in her locked studio. There are no signs of forced entry, and the only thing out of place is a single, empty coffee cup on the floor beside her. The detective are baffled. Can you crack the case?
Solution: The artist was poisoned. The key is the empty coffee cup. If someone had broken in to rob or harm Ms. Monet, they likely wouldn't have bothered to drink her coffee. Therefore, the killer must have been someone Ms. Monet knew and trusted enough to share a cup of coffee with.
