The Wind in the Willows

Burglary at Toad Hall (1x11)

:

Toad opens Toad Hall to the public in order to (modestly) show of his many family heirlooms. But the weasels have a dastardly plan to sabotage his efforts. All Toads possessions begin to disappear, causing him terrible embarrassment. Fortunately, Badger is on hand to save the day.
