Opened in February 1912. Ran 100 performances, to about April 1912. The Greyhound is a 1911 play written by Paul Armstrong and Wilson Mizner. It is a melodrama with four acts, six settings, a large cast and fast pacing. The story is episodic, following four criminals working likely victims on an ocean liner, and showing how they are thwarted. Although containing elements of a thriller, comedy dominates, as a glance at names of featured characters suggests. The title comes from the contemporary description of fast transatlantic passenger ships as "ocean greyhounds". Wiki link
