Brian Jacques: The Pearls of Lutra

This story is another in the series of Redwall (surprise, surprise). In the beginning, a army of corsairs and sea rats attacked and destroyed the small fort of Lutra, in order to steal the Pearls of Lutra, huge creamy rose coloured Pearls, for there hypnotic master, 'Mad Eyes'. But on the way back a rat took the gems from the ships and ran away, leaving the others to face the wrath of the crazy weasel. Finding the gems gone, Mad Eyes sent his army of monitor lizards to do the deed. Meanwhile, the rat makes his way to Redwall and befriend a old squirrel who helps him hide the gems around the abbey with clues that only the cleverest and bravest animals could follow. When the evil lizards arrive in Mossflower forest they secretly kidnap the abbot and a young hedgehog and ask for the gems in return for them. while three abbey-dwellers search for the pearls, Martin of Redwall takes chase of the lizards and finds the only suriver from Lutra who has also sworn to kill the corsairs together they set off to a lonley island on which the fort of Mad Eyes stands...
