In 1980, Eclipse Enterprises published "Detectives Inc.: A Remembrance of Threatening Green", the first of what would become two graphic novels in this series, both written by McGregor. This initial book featured black-and-white art by penciler-inker Marshall Rogers. The second book, "Detectives Inc.: A Terror Of Dying Dreams", followed in 1985, drawn by Gene Colan, and printed directly from his detailed pencils; a later comic-book reprinting added a sepia-tone wash in place of inking. In the American comics market, these two graphic novels were among the first not featuring superhero or science fiction/fantasy stories, and "A Remembrance of Threatening Green" (1980) was the first naturalistic graphic novel to follow Will Eisner's influential "A Contract with God". The Gay League's "LBGT Comics Timeline" cites the book as "featuring the first lesbian characters in mass-market comics".
