S6·E83 Episode 405 (Tue 15th Nov 1977)

It is night time, and Matt has just dropped Dolly at the Vicarage after a night out. As he drives past The Woolpack, a shadowy figure passes in front of his headlight, going away from the pub. Meanwhile in The Woolpack, Henry discovers that the front door is open. He accuses Amos of having neglected his duties but Amos fervently denies this. He wants to call the police but as nothing seems to have been stolen or damaged, Henry tells him not to be so silly. Amos' fears are proved justified the next day though when Sam, in The Woolpack, spots a vacant niche where the Butterworth Ball should be and realises someone has taken it.
