But instead of looking back by 365 days (or 366, this year is a leap year, isn't it?), let's look back a whole lot longer - to the time of expert of prediction, Michel de Nostredame, commonly known as Nostradamus.
In the mid sixteenth century, Nostradamus wrote this:
And lo, in the Templar school,
In seven and thousands two,
Under a new man's rule,
In air, death will blow through.Quatrain 47, Nostradamus
Did Nostradamus predict the chlorine leak? Did the staff ignore the blatant clues? Did everyone at BSF forget swimming pools use chlorine? Has the government covered up students' deaths? Is the new building a way to shamelessly hide Temple Moor's terrible past? Did that idea backfire stunningly? The answer to all of these is a clear and definite yes.
