One or two features of the problem now became more than ever puzzling. First, in view of the fact that I had seen Gabrielle Engledue lying dead and had, for a bribe of five thousand pounds, signed a death certificate purporting to be from Doctor Gordon Garfield, of Queen Anne Street, Cavendish Square, it seemed beyond credence that the girl who had died and been cremated should be led about the streets of Florence by this Italian, Doctor Moroni. Oswald De Gex's denials were, in themselves, only thin, and yet they were all very clever and carefully prepared. The story of how his wife had left his little son in Westbourne Grove to be discovered by the police was no doubt well thought out. De Gex and his wife were actually on most affectionate terms, hence the tale he had told had been purposely concocted, in order to mislead me. Besides, his pretence that the dead girl had been his niece was, of course, a similarly concocted story to mislead me, and also to discredit me if perchance I made any unwelcome inquiries. That I had been half asphyxiated and then drugged until my mental balance had been upset, was quite plain. And it was equally plain that De Gex did not intend that I should be capable of making inquiries concerning the events of that memorable November night. When I had been thrown out of the motor-car on that French highway, near St. Malo, the bank-notes had been purposely left in my pocket. I had already copied the numbers, and had called upon the millionaire's bankers in Pall Mall, but there was no record that any of them had been issued to him. That payment had evidently been very well concealed. On every hand it appeared quite plain that I had been the victim of some strange and remarkable conspiracy, the motive of which was entirely obscure. Surely I must have been watched, and my habits noted. De Gex had known that I frequently passed his door on my way to visit my uncle, and further, he must have known that I should pass on that fateful night in November when Horton was sent out to entice me within. But the chief point of that complex puzzle was the fact that there, in Florence, within a mile or two of the millionaire's almost regal residence, I had encountered a living girl who, in every feature, was the exact counterpart of the poor girl whose death and cremation stood recorded in the official registry at Somerset House! When in London I had been half inclined to call upon Doctor Gordon Garfield and explain the situation. But such confession must, I knew, lead to my prosecution and inevitable imprisonment. I had taken a false step while under the baneful influence of some drug which had stultified my own volition and held me powerless to resist the temptation. I was now endeavouring to seek the truth.
