With only the very best of intentions, Monty Beaumont - Championship Afghan Hound - steals an Ancient Egyptian amulet that transforms him magically into a man and lands him in more bother than is good for anyone. He finds his comfortable world thrown into turmoil when his actions lead him on a cosmic treasure hunt, pitting him against a deadly, supernatural foe. To survive (and return himself to his true form) Monty must first solve a series of riddles that would baffle even the brightest of minds. With the help of several friends (including an enigmatic cat called Caligula) Monty embarks on an adventure that will take him from his sleepy little village to the big city, where more than just his own future will be decided.
