Joan has also written radio plays and documentaries, plus many features for Police Review, the leading police magazine, and Red Herrings, the journal of the Crime Writers Association. The CWA awarded her a Red Herring for her services and the Leo Harris Award for the best contribution.

Dead Centre is the latest of these.
