I thought I had read everything that Norman Hunter ever wrote by the time I was 10. But no! Here is some more! It's set in the same 'verse as The Dribblesome Teapots (and, apparently, as Professor Branestawm, since he is referenced as living in England) and is more of the same comedy Ruritanian shenanigans. One rather cringes, now, at the procession of 'oriental potentates' with silly names. (Everybody has a silly name, of course, but...) Apart from that, good fun.
