A Scanner Darkly was one of the few Dick novels to gestate over a long period of time. By February 1973, in an effort to prove that the effects of his amphetamine usage were merely psychosomatic, the newly clean-and-sober author had already prepared a full outline. A first draft was in development by March. This labor was soon supplanted by a new family and the completion of Flow My Tears, The Policeman Said (left unfinished in 1970), which was finally released in 1974 and received the prestigious John W. Campbell Award. Additional preoccupations were the mystical experiences of early 1974 that would eventually serve as a basis for VALIS and the Exegesis journal; a screenplay for an unproduced film adaptation of 1969's Ubik; occasional lectures; and the expedited completion of the deferred Roger Zelazny collaboration Deus Irae in 1975.
