Curtain at Eight

Curtain at Eight is a 1933 American PreCode film directed by E. Mason Hopper.

That leads him to question Loveley Holmes about the Thorntons and the gambling debts. Handley returns to the theater to find a crowd outside the Property Room. He goes in and finds the room in disorder and Geraldine on the loose. Firing a shot, he orders her to get back in to her cage, to which she complies. Handley then finds the prop master in the room, dead. Gallagher arrives and quickly wraps up the case. As Handley is leaving the theater, he meets Lola. He tells her that he would have done the same thing if that was his sister, meaning that he would have shot Thornton just as she had. He tells her that she does not have to worry, as Gallagher proved it was the chimpanzee that shot Wylie Thornton and that Lovely Holmes will be charged with shooting Alma Thornton.
