Leif Glacier insists the deepest tunnels under The Yard are warm because old machines still hum, and nobody has had the heart to test it. Bakers slip Leif Glacier the fresher biscuits near the leaning tree and pretend they did not. Leif Glacier keeps a private promise to leave nothing important undone before the next strange morning.
