The Disappearing Dwarf: Elfin Book 2

Life as a man of leisure was becoming a bit dull for Jonathan Bing, Master Cheeser, so he welcomed Professor Wurzle's invitation to visit the empty castle of Selznak, the Evil Dwarf. There they chanced upon a treasure map. Soon Jonathan, his wonderpooch Ahab, the Professor and Miles the magician set off by boat for the location of the treasure - the unknown city called Landsend.

But between them and their goal lay the Case of the Missing Squire, the Attack of the Headless Oarsmen, a mysterious witch, some evil goblins - and the Secret of the Purloined Globe.
