"Ah! Mr. Garfield. It is a great trial to me. Poor child! I cannot think what happened to her. Nobody can tell, she least of all. Doctor Moroni has been very good, for he is greatly interested in her case. They have told me that you called some time ago and evinced an interest in her." "Yes, Mrs. Tennison," I said. "I feel a very deep interest in your daughter because--well, to tell you the truth, I, too, after a strange adventure here in London one night completely lost my sense of identity, and when I came to a knowledge of things about me I was in a hospital in France, having been found unconscious at the roadside many days after my adventure in London." "How very curious!" Mrs. Tennison remarked, instantly interested. "Gabrielle was found at the roadside. Do you think, then, that there is any connexion between your case and hers?" "Yes, Mrs. Tennison," I replied promptly. "It is for that reason I am in active search of the truth--in the interests of your daughter, as well as of those of my own." "What do you suspect, Mr. Garfield?" asked Gabrielle's mother, as we sat in that cosily-furnished little room where on the table in the centre stood an old punch-bowl filled with sweet-smelling La France roses. "I suspect many things. In some, my suspicions have proved correct. In others, I am still entirely in the dark. One important point, however, I have established, namely, the means by which this curious, mysterious effect has been produced upon the minds of both your daughter and myself. When one knows the disease then it is not difficult to search for the cure. I know how the effect was produced, and further, I know the name of the medical man who has effected cures in similar cases." "You do?" she exclaimed eagerly. "Well, Gabrielle has seen a dozen specialists, all of whom have been puzzled." "Professor Gourbeil, of Lyons, has been able to gain complete cures in two cases. Orosin, a newly discovered poison, is the drug that was used, and the Professor has a wider knowledge of the effect of that highly dangerous substance than any person living. You should arrange to take your daughter to him." The pale-faced widow shook her head, and in a mournful tone, replied: "Ah! I am afraid it would be useless. Doctor Moroni took her to several specialists, but they all failed to restore her brain to its normal activity." "Professor Gourbeil is the only man who has ever been able to completely cure a person to whom orosin has been administered--and that has been in two cases only." "So the chance is very remote, even if she saw him," exclaimed the widow despairingly. "I think, Mrs. Tennison, that Gabrielle should see him in any case," I said.
