Twists and turns abound in the final instalment of the Spiderwick Chronicles.
Bruised and battered, Jared, Simon and Mallory return home to find their house completely ransacked and discover that Mulgarath has made off with their mother and Spiderwick's Guide. Its up to the Grace kids, with only the help of Thimbletack, Hogsqueal and Byron, to defeat the evil Mulgarath and his goblin army. But first they have to rescue Arthur Spiderwick from Lorengorm and the elves!
