The Duke of Dullitch is in distress - several reports are coming in that the city is beginning to be over-run by a plague of rats. Naturally he has killed off all witnesses, but daily the problem is becoming more obvious. His corrupt council, led by the hapless ex-wizard Tambor has no solutions. He must send for mercenaries to rid his city of the rampant rodents. Heralds ride out from every gate, each hoping to bring back the saviour of the city.Part-time herald, full-time thief, and grandson to Tambor, Jimmy Quickstint is the lucky man - falling haphazardly upon the skills of Diek Wustapha - a charmer - recently inhabited by magic and suddenly irresistible to girls, sheep - and rats. Diek fulfils his task and is promised 500 pounds for his troubles. But once the rats have gone, the council renege on their deal. Full of anger (and magic), Diek charms the children of Dullitch out of the city, playing on his mouth organ, where he disappears into the caves and woodland of the surrounding area.The Duke is now in despair. Jimmy and his useless friends Groan, a barbarian mercenary, and Gordo, a dwarf - decide they will bring the children back, and garner a huge reward...
