An old wealthy man of great property invites all his children and their consorts to dinner to tell them he is changing his will. He intends to give over his great mansion to his son Henry, on condition that he gives up his fiancée, a lovely young actress. Henry of course is infuriated and walks out, and his girl tries to run away from the house. Meanwhile the old man gets shot in his library, his other son was there with him and is holding a gun when the others enter all upset, but that gun is not smoking. He claims he saw another person out in the dark, whom he tried to pursue and shoot at but did not get, using his father's pistol. His wife is Greta Gynt and the leading character here, a thriller writer, who if anyone should be able to figure out the mystery, which she eventually does. But the murderer once again gets away in the night.
It's almost an Agatha Christie mystery involving poisoning and a suspected butler, while there is only one person above suspicion - Katie Johnson, who would have inherited the lot if Henry had stuck to his love, which he did. They get away to get married. It is great entertainment with a wonderful dialog, and you won't risk falling asleep - the intrigue keeps constantly thickening.
