Ever since he arrived in Paris, Henry the Rat has made a pretty good living selling "magic" swords to gullible knights. But when Henry sells one to Geoffrey Plantagenet, brother to King Richard, his happy days are over for good. Geoffrey forces Henry into a dangerous, uncomfortable quest for the most famous magic sword of all time, Excalibur, even though Henry is certain that it's just a myth.
