Imagine, you are a servant of a dying philanthropist. One day, that philanthropist, did in fact, die, but orders you to take care of his mansion even after his death. He has no heirs and has nobody to track your every move inside his house. What would you do? Well, Gran would become more than a decent servant and maintain the mansion, and on top that, make everything a routine for 20 years. Timed and clockwork. However, now, get this. You are Gran. You have made a habit of waking up, cleaning the house, read, then sleep... for 20 years, and suddenly, a strange letter from your late master suddenly arrives at your doorstep telling you to do odd things. Would you follow it? Gran definitely would.
