In about a quarter of an hour the woman came out. She wore no veil, and, as it was still fairly light, I had no difficulty in seeing her face. She passed hurriedly by me in the direction of the Haymarket without observing me, and I recognized her at a glance. It was, as I thought, Rose Strent, and none other. In place of the waiting maid's linen dress she was arrayed in a smart tailor-made costume, and looked very fashionable indeed. Her face wore a triumphant expression, as though she had been successful with Felix. I guessed the interview had been for the purpose of extorting blackmail. With her knowledge of his secret Felix was certainly at her mercy. Following her up at some little distance, she went down the Hay-market and turned into one of the side streets; turned off there into a dirty little alley, and finally disappeared into a swing door over which was a lamp inscribed with some letters. I looked up and saw written thereon "Stage Door." "An actress!" said I, and went round to the front of the theater to inspect the play-bill. It was the Frivolity Theater, and they were playing the burlesque of "As You Don't Like It." Glancing down the list of characters, I saw that _Orlando_ was played by Miss Rose Gernon. "A leading lady," I thought, transfixed with astonishment. "A burlesque actress, doubtless, in the receipt of a good salary. What in Heaven's name took her to the Fen Inn?" This question I was of course unable to answer, but I guessed it had something to do with love and Felix Briarfield. Leaving the matter alone for a few moments, I secured a stall, and entered the theater. When _Orlando_ came on, I was thoroughly satisfied. Rose Strent was Rose Gernon, and I had seen her play the part of waiting maid at the Fen Inn on the 10th of June, that fatal night of the murder. CHAPTER X. A WOMAN SCORNED. When I told Dr. Merrick of my good fortune in finding Rose Strent, or, to use her stage name, Rose Gernon, he was considerably astonished. The case had taken hold of him so completely that he could think of nothing else. He had a large practice, and attended fairly well to his patients, but informed me that he did so in a mechanical fashion, more or less, as his brain was busy with the Fen Inn mystery. We were now wonderfully familiar, considering the short period of our acquaintance, but this was doubtless due to the interest we both took in the case. "Upon my word, Denham," said Merrick, rubbing his head irritably, "I wish you had not come near me with your hallucinations. Instead of attending to my business I think of nothing but your mysteries. The sooner we unravel this riddle the better will it be for me. You are an idle bachelor, so it does not matter much to you, but I am a busy medical man, and this infernal business worries me greatly. At this moment I ought to be attending to a patient, instead of which I am wasting my time with you." "Shall I go away?"
