After seeing the beastly Margoletta moored clean across the nests of his beloved coots, Tom set the motorcruiser adrift. Now the enemy have offered a bounty on his head. Can they save the birds' nest from almost certain destruction? Will they avoid being caught by the awful Hullabaloos? Only some brave friends and quick thinking stands between them and disaster...
