Fire Drill Bookshop (Night of 05/01/2017)

I am working (possibly on a college course?) in Harrow. There is a fire-alarm. It is unclear whether or not it is a drill or a real fire. I am in a rush but decide that I must take my bag with me - even though I am aware that we are told to leave any possessions behind in the case of a fire. Once outside Id ecide that I might as well take this opportunity to visit a bookshop in the town centre. The bookshop is located at the end of a darkened and empty arcade, and is called something like 'Mole's Books' - referring to the fact that moles are nocturnal creatures existing in the dark - much like the bookshop.  I am unsure if the bookshop is open, but when I approach the window, I am relieved to see people walking about the bookshelves in the dim light of yellow bulbs. I enter the bookshop but am immediately concerned that my presence will be missed back at college, Surely they will take the register, and discover that I am missing - they will think I am in the building. I am afraid that I will get into trouble and immediately start working out whether I can return before my presence will be misssed.
