I always figured that in the world of Missing Monday there would be rumors that the clocktower is haunted. Someone's cousin's best friend absolutely witnessed weird stuff happening there so all the locals stay away from it, you know? I tried writing a short comic about it but it never quite came together (though I was happy to get to reference that idea again in a much later chapter).

Suffice to say even in world, Foyle should absolutely not OPEN THAT DOOR.
