The Puzzle: A renowned clockmaker was found dead in his locked workshop. The only things in the room were:

• A grandfather clock, stopped at 3:17.
• A table with tools and clock parts.
• A note with the following inscription: "Time waits for no one, but a broken chain binds all."
• A single, perfectly formed ice cube on the floor, slowly melting.
• A window, securely locked from the inside. The police have ruled out natural causes and suicide. How did the clockmaker die?
