Greet Liégeois is the wife of comic scriptwriter Hugo Renaerts. She has helped her husband with the scripts for series like 'Bessy' and 'Silberpfeil', that were produced for the German market in the 1970s and 1980s. When Frank Sels, the artist of 'Silberpfeil', couldn't keep up with the production, she ghosted as an artist on several 'Silberpfeil' stories. Since Liégeois and Renaerts live in Spain, for many years there has been a rumour among fans that there was an anonymous Spanish artist working on the stories. Greet Liégeois has also written scripts for the Jeff Broeckx series 'Sloeber' and 'Dag en Heidi' in the 1980s.
