There are moments when images flash into my mind and some of them even look a little like this poster. I'm sure that I've spent too much time reading pulp fiction and watching film noir.

OK, depending on how you start counting, we have either 39 or 40 steps going up the Armstrong building stairs -- there may well be many mysteries in the Armstrong building but I don't think these steps will lead to the answer!!! I think I will keep looking as I rather fancy the spiral stairs even though they appear to be out of bounds now.
