July 19. — This very good detective story, by J. Searle Dawley, is the second in the "Kate Kirby Cases" and makes what probably is the best regular release of the last two weeks. The situation at the opening is finely dramatic and it gets a tremendous impetus from the early development of the plot. At the start, we find Bigelow Cooper and Bessie Learn about to be married. Bigelow has discovered that Bessie's older sister, May Abbey, is the one whom he really loves. She returns his love; but won't hear of his breaking Bessie's heart and insists on his going on with the ceremony. She has been interrupted while writing a note to him to this effect, and has slipped it down beside a settle. A few moments later the bride-to-be is found dead on the broad stairway. When the detectives come, it is found that Bigelow's knife killed her, and when May's unfinished note is also found, it looks as though he had murdered her. May does not know that he is innocent, nor does the spectator. One of the detectives is a woman, Laura Sawyer, and when the inspector, Robert Brewer, tries to wring the truth out of May, her sympathies are so worked up that she goes out to make further investigations, believing they will clear May and Bigelow. This we think is the picture's most brilliant scene; but the whole of it is very clever. The acting, photography and direction are all worthy of the best commendation.}} Kate Kirby's
