I’ve watched many many episodes w my daughter throughout her teen years. We just rewatched the insanity that is the Sword of Guillame and decided it is the quintessential MM episode. It has everything!
shady land deal, ancient ancestors, imperious titled family, beheadings, priest, anonymous letters, blocked walking path, Barnaby getting hit on by town sexy woman, bus trip to the sea, absolutely bizarre motive, town council meetings and Jones on a tear the entire episode! All because his lunch was interrupted! He does his best work hangry!!
