After Spare's death, Grant began to focus more on his own writing career. From 1959 to 1963, Grant privately published the Carfax Monographs, a series of short articles on magic published in ten instalments, each at a limited print run of 100. Nine of these volumes included original artworks produced by Steffi, reflecting the increasing collaboration between husband and wife which would be reflected in many of Grant's subsequent publications. The Carfax Monographs would eventually be assembled together and re-released as Hidden Lore in 1989. In 1966 he also privately published a small book of his poems, Black to Black and Other Poems. During the 1950s and 1960s Grant also authored a number of novellas, although these would only be published by Starfire Publishing between 1997 and 2012.
