Glass tells the story of Günter Glass, an ex-milkman and aspiring window-cleaner.
Naïve young Günter has a head for heights and, ever since he visited a glassblower’s workshop as a child, an unusual fixation with glass. When a minor adventure up the spire of Salisbury Cathedral makes Günter a local celebrity, John Blades – window-cleaner to the stars – comes calling. He wants Günter to join him in London to clean Europe’s tallest skyscraper, the newly constructed Shard in London Bridge. Will Günter find his way along the straight and narrow? Or will his innocence put him on collision course with the frequently baffling modern world?
