Episode 2: The Mystery of the Sleeping House
R: Howell Hansel, Frederick Sullivan. B: Lloyd Lonergan (scenario), Daniel Carson Goodman (story). K: Carl Gregory. D: Marguerite Snow, James Cruze, Harry Benham, Sidney Bracey, Frank Farrington, Mary Elizabeth Forbes. P: Thanhouser Film Corporation. USA 1914

“This is Episode 2 of the Zudora series. It carries with it an air of Oriental mystery. Zudora saves her lover from certain death in the contracting cell. The use of fumes from the lotus flower to put the Hindu band to sleep was a novel feature. This pays particular attention to settings and costumings and proves an attractive offering throughout. Zudora gives a good account of herself in working out this problem, and the series promise as well for the future.”
