On the fourth day he returned, for I saw him in his big yellow car driving along the Via Calzajoli. An elegant Italian, the young Marchese Cerretani, was seated at his side, and both were laughing together. Twice I had been up to the Villa Clementini, and wandered around its high white walls which hid the beautiful gardens from the public gaze. Surely there was no fairer spot in all sunny Italy than that chosen by the rich man as his abode. To the hundreds of visitors of all nations, who came up by train to Fiesole from Florence to lunch or dine at the various pleasant little restaurants, the great imposing place was pointed out as the residence of the rich "Inglese"--the man who possessed more money than any of the most wealthy in the kingdom of Italy. When I thought of that fateful night in Stretton Street, I waxed furious. Was it possible, that, by the possession of great riches, a man could commit crime with impunity? Perhaps what goaded me to desperation more than anything was the foul trick that had been played upon me--the administration of that drug which had caused me to lose all sense of my own being. That subtle odour of _pot-pourri_ had gripped me until I felt faint and inert beneath its perfume, and it often returned to me--but in fancy, of course. In the winter sunshine I wandered about the busy, old-world streets of Florence, idling in the cafés, gazing into the many shop-windows of the dealers in faked pictures and faked antiques, while often my wandering footsteps led me into one or other of the "sights" of the city, all of which I had visited before--the National Museum at the Bargello, the Laurenziana Library, with its rows of priceless chained manuscripts, the Chiostro dello Scalzo, where Andrea del Sarto's wonderful frescoes adorn the walls, or into the Palazzo Vecchio, or the galleries of the Pitti, or the Uffizi. I was merely killing time in the faint hope that the good-natured Robertson might get for me the information which, in the circumstances, I was naturally most eager to obtain. In the course of my erratic wanderings through the grand old city, with its host of monuments of a glorious past, I was one morning passing the great marble-built cathedral and noticed a number of people entering. There seemed to be an unusual number of visitors, so having nothing to do I passed through the narrow door into the sombre gloom of the magnificent old place--one of the most noteworthy and most beautiful sacred buildings in the world. At first, entering from the bright sunshine of the piazza, I could scarcely see, so dim was the huge interior, but slowly my vision, rather bad since my strange adventure, grew accustomed to the half-darkness, and I saw that upon the high altar there were many long candles burning in their brass sconces and before the high altar three priests in gorgeous vestments were kneeling.
