Magic died out in 1851, with the advent of the technological age brought about by the Great Exhibition, but through an ingenious use of quantum physics, magic is reborn again in the present day, allowing members of D.O.D.O. to travel back in time to conduct missions which change our own socio-political realities. A satire on government bureaucracy and a brilliantly staged thought experiment on quantum physics. A time travel race-against-time thriller.
