The train was a slow omnibus one, and it was past midnight before we drew into the station of Tivoli. I held back, allowing all three to alight before me, and saw that, on the platform, they separated and passed out singly, as though unacquainted. A detective was idling at the barrier as is always the case in Italy, but their appearance did not attract him and they took the dark road leading towards the ancient town which in the daytime commands such beautiful views of Rome and the Campagna, the town that has always been a popular summer resort even since the Augustan age when Maecenas, Hadrian and the Emperor Augustus himself had their villas there, and gave their marvellous fetes. As I followed the trio, who still walked separately, I could hear the quiet of the night was broken by the thunder of the giant waterfalls, for me a fortunate circumstance, as the sounds of my footsteps were deadened. In Miller a strange transformation had been effected. He had been conspicuous in his suit of white, yet now he was in dark clothes. He had adopted the trick often practised by malefactors of wearing one suit over the other, so as to be able to enter a place wearing a light suit and gay-coloured scarf, and leave it three minutes afterwards dressed entirely differently. He had simply slipped off his white cotton suit while in the train and had either thrown it out of the window, or left it beneath the seat of the railway-carriage. Railway searchers and platelayers, even in England, find complete suits of clothes more often than one would imagine. From the station at Tivoli the road to the town, part of the ancient Valeria, runs down to the St Angelo Gate. There it branches out in two ways, one entering the town across a high bridge, and the other continuing up the hill and out into the country. The three men took this latter road, a winding tortuous one which led up past an ancient castle and away to the heights behind. There were no lights, but the night was not exactly dark, and I could distinctly see the white road before me and the figures moving forward. One had gone on rapidly in front, while the other two also walked separately as though strangers. Suddenly I saw the figure nearest me leave the road and pass into a vineyard. Then a few minutes later, as I went on, I lost sight of the other two and at the same time found that we had reached a splendid old _cinquecento_ villa, an enormous place the back of which abutted on to the road. Its great square windows were closely barred as they had been in those old turbulent days when every house had been a fortress, and from the great entrance gate with its crumbling stone lions on either side ran a long dark cypress avenue. The ponderous gate was covered with sheet iron so that I could see only the tops of the trees within. This was, I supposed, the Villa Verde, the country-house of the man who had died unrecognised in the boarding-house in Shepherd's Bush.
