A Glasgow institution has taken to Twitter after taking on a "starring role" in the new series of Shetland.
The hit BBC Scotland crime drama returned for its seventh series last week, which sees Jimmy Pérez and Alison "Tosh" McIntosh investigate a graphic novelist who has gone missing.
Eagle-eyed Glasgow viewers who tuned in may have noticed something familiar about the 'Shetland library' featured in the show.
