As it struck me I should not find my theory in Italy, I packed up my belongings and hastened from Verona. At Naples I picked up a Messageries Maritimes steamer and began a circular tour in the Levant. At Alexandretta I went ashore, and inquired my way to the dwelling of the Prefect of Police. I did not call on Hamdi Effendi. But I wandered round the walls and wondered in a moody, heart-achey way where it was that Carlotta sat when Harry came along and whistled her like a tame falcon to his arm. It was a white palace of a house with a closed balcony supported on rude corbels and tightly shuttered. At the back spread a large garden surrounded by the famous wall. There was no doubt that Hamdi was a wealthy personage, and that Carlotta’s nurture had been as gentle as that of any lady in Syria. But the place wherein Carlotta’s childhood had been sheltered had an air of impenetrable mystery. I stood baffled before it, as I had stood so often before Carlotta’s soul. The result of this portion of my search was the discovery, not of a new theory, but of an old pain. I went back to the ship in a despondent mood, and caused deep distress to one of the gentlest creatures I have ever met. He was a lean, elderly German, who no matter what the occasion or what the temperature wore a long, tight-buttoned frock-coat, a narrow black tie, and a little bluish-grey felt hat adorned with a partridge’s feather which gave him an air of forlorn rakishness. His name was Doctor Anastasius Dose, and he spent a blameless life in travelling up and down the world, on behalf of a Leipsic firm of which he was a member, in search of rare and curious books. For there are copies of books which have a well-known pedigree like famous jewels, and whose acquisition, a matter of infinite tact, gives rise, I was told by Herr Dose, to the most exquisite thrill known to man. He brought me on that morose afternoon a copy of the “Synonima,” in Italian and French, of St. Fliscus, printed by Simon Magniagus of Milan in 1480, and opened the vellum covers with careful fingers. “In all the assemblage of human atoms that inhabit this vessel,” said he, “there is but one who is imbued with reverence for the past and a sense of the preciousness of the unique. I need not tell you, Herr Baronet, who are a scholar, that of this book only two copies exist in this ink-sodden universe. One is in the University Library of Bologna; the other is before your eyes. It is also the only book known to have been printed by Magniagus. See the beautiful, small Roman type--a masterpiece. Ach, Herr Baronet! to have accomplished one such work in a lifetime, and then to sit among the blessed saints and look down on earth and know that the two sole copies in existence are cherished by the elect, what a reward, what eternal happiness!” I turned over the pages. The faint perfume of mouldy lore ascended and I remembered the smell of the “Histoire des Uscoques” in the Embankment Gardens.
