In a series of flashbacks over Professor Figwort’s eighty-year life, we learn of his first
love letter (the failure of which prompted his discovery of time travel) and his three
subsequent great discoveries.
It was then that he devined a solution to his new-found problems: he would travel back in
time and stop himself from disturbing Miss Bonsoir in the first place—on any level,
molecular or otherwise. Yes, that ought to do it. While he was there, he might even
return those now-overdue library books.
