This photo in today's Le Figaro reminded me of the last episode of one of Jack's earlier short stories, in which a small elite tries to keep a certain monopoly as long as possible. That proves finally impossible, leading to a conclusion similar to the scene depicted (if one overlooks the ropes and attributes the acrobats' elevated positions to a newly acquired skill). The title of the story was used in the Netherlands as the general title of a collection of Jack's lesser known short stories. The title is also identical with a Hungarian noun meaning "building plot" which is also used as a surname, although the adjective ending in -i derived from this noun is more popular as a surname (a famous Hungarian family of counts bears that name, among them a controversial prime minister between WW I and WW II and a famous Hungarian explorer of the unknown East-African highlands;he "discovered" a big lake, now famous for its paleolithical remains, although the locals had discovered it before him, of course). And finally, a google search reveals that it's also the name of a popular band on Papua New Guinea.
