The house -- actually a 5th Avenue apartent in New York City -- was designed by architect Eric Clough for a family of 6. After the father requested a poem he had written be hidden somewhere in the house, Clough went on a puzzle building spree intended to "spark a child's mind."
In any case, the finale involved, in part, removing decorative door knockers from two hallway panels, which fit together to make a crank, which in turn opened hidden panels in a credenza in the dining room, which displayed multiple keys and keyholes, which, when the correct ones were used, yielded drawers containing acrylic letters and a table-size cloth imprinted with the beginnings of a crossword puzzle, the answers to which led to one of the rectangular panels lining the tiny den, which concealed a chamfered magnetic cube, which could be used to open the 24 remaining panels, revealing, in large type, the poem written by Mr. Klinsky.
