As greedy Doctor Klumpet and crafty Mister Scarab go about their business, they have no idea that they are being followed by a green floppy hat, a weather-stick, and a small nightingale. It is only when the Big People recover – surprisingly well – that they realise a tree-troll has been paying visits too.
Finnr is a talented medicine-maker. He knows which herbs and flowers to mix together; which seeds and leaves to collect. His notebook is a precious record of a lifetime's work and if lost, could never, ever be replaced.
But Doctor Klumpet is furious!
And Mister Scarab has a plan...
How can the tree-troll protect all that is dear to him?
Will he ever feel safe again?
