"Of course I shall help you," snapped the barrister, sharply. "I want to get at the truth as speedily as possible, so that we may be married. And to aid you in your search I now make a suggestion." Audrey looked at him with interest. "What is it?" "You say that your father admired Madame Coralie when she was Flora Arkwright of Bleakleigh. Very good! Flora Arkwright may have admired your father, and may have grudged him marrying your mother. Now, why not go to Madame Coralie straight away and rouse her jealousy?" "Rouse her jealousy?" "Yes. The Deceased Wife's Sister Bill is law now, and there is no bar against Madame Coralie marrying Sir Joseph." "Yes, there is. You forget Eddy Vail." "Oh, the deuce!" cried the barrister, in dismay, "so I do. Never mind, it is as well to try the experiment. Tell Madame Coralie that Sir Joseph is to marry Rosy Pearl, and see what she will say. For your dead mother's sake, if not for her own, she may resent the marriage." "Of course, the idea is absurd," said Audrey, pettishly. "My aunt has not a shadow of excuse to object to my father marrying anyone. What ever feelings she may have entertained for him once, they have been parted too long for such feelings to exist now." "Well, the experiment is worth trying," insisted Ralph, anxiously. Audrey thought for a moment, then rose and walked across the grass. "To set your mind at rest I shall see my aunt at once and tell her." "Good! I shall wait at the door of the Pink Shop and hear your report." With this understanding the two strolled across the Gardens to Walpole Lane, and while Ralph lingered on the pavement Audrey passed into the Turkish shop. She had chosen rather an awkward hour for an interview, as Madame Coralie's clients were rolling up in carriage and motor-brougham. But the proprietress of the shop was upstairs in the still-room, and sent down word that she would see Miss Branwin at once. The girl soon found herself in the presence of her aunt, while Badoura, who had introduced her, returned to look after the customers, who were being served by the other three girls. "I can only give you five minutes, my dear," said Madame Coralie, who was again wearing her yashmak. "Is there anything wrong?" "Nothing particularly; but I thought that it was just as well you should know that my father has made up his mind to marry again." "What!" Madame Coralie gave a roar like that of a wounded lioness. "Who is the woman?" "Miss Rosy Pearl, of the--" "That music-hall creature--impossible!" Madame Coralie clenched her hands, and her black eyes looked extremely angry. "Why, it was Rosy Pearl who was my other customer who slept in this house on the night of the crime!" "Oh!" Audrey grew pale. In a flash she saw what Madame Coralie meant. CHAPTER XIII A BLIND CLUE
