Clockmaker's House

You have been summoned to the country house of Professor Archimedes Smith, also known as The Clockmaker for his notoriety in the design of automata and mechanisms for all sorts of applications. As admirers of Professor Smith's work, you also know that he is said to be quite obsessive and even paranoid, and in fact, he has been absent from the public scene for a long time. The invitation specifies that the caretaker of the estate will wait for you at the agreed time at the entrance and that he also has something to deliver to you... Will you accept the invitation?
