"Only in the half-darkness, when she came to the door at half-past eight to tell me that my mother would remain for the night."
"Then," said Perry Toat, rising, "go to the Pink Shop and see her now. You are so straightforward and earnest that you may succeed where I fail. Ask all the questions you can think of, and see what Madame Coralie looks like."
"Hear what she says, you mean."
"No, I do not. Hear what she says, of course; but you may be sure that if she has anything to hide she will be most guarded in her answers. But look into her face, and watch the change of colour, and--oh!" Miss Toat stopped in dismay. "I forgot, Madame Coralie wears a yashmak constantly."
"In that case I shall get her to remove it," said Audrey, quickly. "I see what you mean, and I shall manage in some way to see her face. If she is guilty I shall know somehow."
"I wish I could come with you myself," said Miss Toat, hastily following Audrey to the door, which opened into a small outer office; "but I fear that Colonel Ilse--ah! here he is."
Miss Branwin saw before her a slender and very straight man, with a grey moustache and grey hair, with a tanned face and a general military look. He had kind blue eyes, and when he saw so pretty a girl emerge from the dingy office of Perry Toat these same eyes lighted up with admiration. With a bow to the detective he stood on one side to let the girl pass. Audrey gave a swift glance at his clearly-cut face as she went out. There seemed to be something familiar about Colonel Ilse's countenance; but she could not say precisely what it was. Besides, her mind was too much taken up with the late conversation with Miss Toat to concern itself with so trifling a matter. The detective accompanied her to the outer door.
"See me to-morrow at three o'clock," she said, in a low voice, "and tell me if you have succeeded in getting Madame Coralie to remove her yashmak."
Miss Branwin readily promised this, as she felt that she needed Miss Toat's professional assistance in the quest which she was now undertaking. She felt eager to reach the Pink Shop and to question Madame Coralie, and her heart beat quickly as she climbed into a 'bus which would take her to Kensington. Sir Joseph would have been furious had he seen his daughter travelling on so humble a vehicle; but Audrey enjoyed the novelty of the sensation. Indeed, she was beginning to find out, for the first time since her mother's death, that life was worth living. And, although she did not know it, she was suffering from a severe attack of detective fever.
The progress of the 'bus seemed slow to the impatient girl; but in due time she came to Kensington High Street. Here she alighted, and turned into Walpole Lane without delay. Shortly she found herself before the mysterious door of the Pink Shop, and entered with a beating heart and a general sense that there was a crisis at hand.
