Originally written in 1974, Definitely Maybe is here presented in its first ever unexpurgated edition. Its protagonist, Dmitry Alekseyevich Malyanov is an astrophysicist; just as he begins to realise that he is on the verge of a revolutionary discovery worthy of a Nobel Prize, his life becomes plagued by strange events. Malyanov suspects that his discovery is in the way of someone (or something) intent on preventing the completion of his work. An explanation is proposed by Malyanov's friend: the force is the Universe's adverse reaction to mankind's scientific pursuit.
