Pretty, young Catherine Harewood is walking to the market early one morning to surprise her father with some fresh mushrooms. As she passes a gambling house, she hears a gunshot and two young men emerge. One man falls dead on the pavement and the other is Henry Felitham, a handsome young man Cathy recognizes from seeing him previously at a dance. Henry is holding a smoking pistol in his hand. This incident propels the proper young Catherine into a world of prisons and courtrooms as a murder trial unfolds and the fate of Henry may rest with her testimony. But, what is the connection with the mysterious Spanish Woman, who lives in a grand house and supposedly has friends in 'high places'? Who else was in the gambling house at that time of the morning before it had opened? What about the whispered conversations between Cathy's father, Mr. Harewood, and his friend, Mr. Mead, a prominent attorney prosecuting the case? Things are not always what they may seem...
