THE GATE OF THE SUN The spring morning was grey and rather threatening as I left the Hôtel de la Paix in Madrid and walked from the Puerta del Sol past the smart shops in the Carrera de San Jeronimo and across the broad handsome Plaza de Canovas, in order to meet Hambledon at a point which he had indicated in the Retiro Park. Late on the previous night I had arrived in the Spanish capital, and while Hambledon was at the Palace Hotel in the Plaza de Canovas I had gone to the Paix in the Puerta del Sol. I had been in Madrid only once before in my life, and as I walked through the gay thoroughfares I recalled that proud saying of the Madrileños: "De Madrid al cielo y en el cielo un ventanillo para ver á Madrid" (From Madrid to Heaven, and in Heaven a loophole to look at Madrid). The Spanish capital to-day is indeed a very fine city, full of life, of movement, and of post-war prosperity. Crossing the Prado, where the trees were already in full leaf, I took that straight broad way which led past the Royal Academy, and again crossing the Calle de Alfonso XII came to the Alcahofa fountain, the Fountain of the Artichoke, near which I waited for the coming of my friend. I stood there upon ground that was historic, and as I gazed around upon that sylvan scene, I wondered what would be the result of our long journey from Rivermead Mansions. That beautiful park which, in the seventeenth century, had been laid out with such taste by the Conde-Duque de Olivares, the favourite of Philip IV, had been the scene of innumerable festivals which swallowed millions of money, and gave rise to many biting "pasquinas" and "coplas." To-day it is the Hyde Park of Spanish Society. There all the latest Paris fashions are seen at the hour of the promenade, and everybody who is anybody in Spain must be seen walking or riding along its picturesque paths. I had not long to wait for Hambledon, for after a few moments his familiar sturdy figure came into sight. "Well, Hughie!" he exclaimed, as we sank upon a seat together. "There's some deep game being played here, I'm certain!" "What game?" I asked quickly. "Ah! I can't yet make it out," he replied. "But I'll tell you what's occurred. Suzor, on arrival, went to the Ritz, where he has a private suite, and after I had watched him safely there I took up my quarters at the Palace on the other side of the Square, and started to keep a watch upon our friend. I got the concierge at the Ritz to do something for me for which I paid him generously, so as to pave the way for information concerning Suzor, in case we may want it." "Good," I said. "There's nothing like making friends with a concierge. He knows everything about the visitors to his hotel, and about their friends also."
