A man wearing a regulation face mask opened the door for them and handed Dunworthy a very damp flyer. Dunworthy asked at the admission desk for Mary and then read the flyer. In boldface type it said 'FIGHT INFLUENZA. VOTE TO SECEDE FROM THE EC'. Underneath was a paragraph: 'Why will you be separated from your loved ones this Christmas?
