While Cluny plans to recapture the tapestry by burning down the abbey gates, Matthias determines to renew his search for Martin's sword but does not know where its keeper, Asmodeus, hides. He learns that only the fierce mouse-eating owl, Captain Snow, knows where he is. To ask him Matthias has to pass the gigantic marmalade cat, Squire Julian Gingivere, and the Shrew of Mossflower Wood! Matthias breaks off the search for the sword to return with his new allies to once again beat Cluny.
