It was dark when I reached the visconte’s house to wait for Vasco, and I had no fear that he would penetrate my disguise.

There was one trouble I had to guard against—the danger of the streets. The fact that a man of my apparent position was lurking about in such a neighbourhood might easily attract the attention of the police, but I was saved from that embarrassment by Miralda’s punctuality.

I had scarcely found a hiding-place when a carriage drove up and she and Inez alighted from it and entered the house. She had gone to Inez in order not to meet Vasco until the hour we had agreed.

Three minutes afterwards he came out and hurried away at a rapid pace, and the spy work commenced in earnest. While we were in the quieter streets, I followed at just sufficient distance to keep him in sight; but when he turned into the Rua Sao Benito I hastened to close up, for fear of losing him in that somewhat busy street.

As I hurried round the corner I nearly plumped into him. He stood looking about him, and I stopped and rolled a cigarette to fill the pause.

It turned out that he was waiting for a tram-car, and when he boarded it I had no option but to risk discovery and follow him. He sat close to the door and I passed him, with my face averted, choosing a seat on the same side, but at the other end.

He was in a condition of extreme nervous excitement and had been drinking freely, probably to drown his fears. He sat with his hands plunged in his pockets and took no notice of any one; and even when the other passengers got out at the Square of St. Paul, leaving him at one end of the long seat and me at the other with no one between us, he took no notice of me.

I had now lost Burroughs, of course. He had hung behind until he had missed the car; but this was perhaps all the better. If he had been in the car, Vasco might have recognized him.

When we reached the Praca do Commercio, Vasco got up and jumped off and hurried along the Rua da Alfandega. There was little fear of my attracting notice here as there were still plenty of people about, and I had no difficulty in following him.

I guessed now that he was making for the landing-stage near the Artillery Museum, and just as he reached that building he was accosted by two men in the dress of sailors. He drew back nervously at first, with a sharp stare; then began to talk to them; and they walked on together.
