Arnold lived most of his life in anonymity. After leaving school, he spent most of his time working as a bookmaker; initially for his uncle and then for himself after he inherited his uncle’s business. He remained in the trade until his death. He never married or had children and lived alone as far as anyone knows. He probably should have been a serial killer.
Fortunately, he found a different hobby, that of writing. He seems to have produced mainly for his own entertainment rather than with the aim of getting published. But he did not go unnoticed forever. A friend, who read one of his novels, was impressed. After some cajoling, Arthur contacted a few publishers. Greenlane Publishing took a risk and Arthur met with middling success in the late seventies and early eighties with his Technomancy series. In the vein of Edgar Rice Burroughs Barsoom, Technomancy features a central hero engaged in a series of adventures against a collection of exotic enemies. The series is known for its use of pseudo-technology in place of traditional magic. It is also notable for its central hero being female.
Although Arthur never found large-scale success, with the seven volumes of the Technomancy series being his only published work, his creations have been cited as sources of inspiration by later authors. A man of few words in every other aspect of his life, Arthur was happy to let his novels stand on their own merit. Out of print since the end of the eighties, the first three novels will be available again as e-books sometime later this year.
