It is 1912, and at Cambridge University the modern age is knocking at the gate. Fred Fairly, a Junior Fellow at the college of St Angelicus, where for centuries no female, not even a pussy cat, has been allowed to set foot, lectures in physics. Science, he is certain, will explain everything. Until into Fred's orderly life come Daisy. Fred is smitten. Why have I met her? He wonders. How can I tell if she's quite what she seems? Fred is a scientist. To him the truth should be everything. But even scientists make mistakes.
