Cole wrote at least seven books for the Left Book Club, all of which were published by Victor Gollancz Ltd. They are marked with LBC in the list of his books given below. He and his wife, Margaret Cole, together wrote 29 popular detective stories, featuring the investigators Superintendent Wilson, Everard Blatchington and Dr. Tancred. Cole and his wife created a partnership but not a marriage. Cole took little interest in sex and he regarded women as a distraction for men. Margaret documented that comprehensively in a biography she wrote of her husband after his death.
