“Several people, signore. One man, well-dressed, like a gentleman, stood for a moment looking up at the window yonder as though he expected to see someone there. But he was apparently disappointed, and passed on.”

“What kind of man?” I inquired eagerly. “Describe him.”

“A signore with small, fair moustache, about forty. He carried an umbrella, so I could not see his face very well. He was tall, and walked erectly, almost like an officer. A four-wheeled cab waited for him up at the corner.”

“He didn’t actually pass the house?”

“No, signore. He merely walked down here sufficiently far to obtain a view of the window; then, having satisfied himself, turned back again.” In reply to my question, Enrico told me that he lived with his mother in Kirby Street, Hatton Garden, the thoroughfare running parallel with Saffron Hill. They have been five years in London: five sad, despairing years. Ah, the English! they were not cattiva. Oh, no! It was their amazing climate that made them what they were. He pitied London people. How happy they would all be if they only lived under the blue sky of rural Tuscany! And so he went on, just as every poor Italian does who is doomed to the struggle and semi-starvation of life in our grey metropolis.

I read the young fellow’s character like a book. He had served his military service at Bologna, and had been waiter in the officers’ mess. Then he and his mother emigrated to London from Genoa, attracted by the proverbial richness of the Inglese and the report that waiters in restaurants were well paid. On arrival, however, he had soon discovered that the supply of Italian waiters was much in excess of the demand; therefore, he had been compelled to invest the ten pounds he had in a second-hand organ, and he and his mother picked up a living as best they could in the unsympathetic streets of London.

He seemed a good fellow, quite frank, and possessing that easy-going, careless manner of the true Tuscan, which never deserts him even when in circumstances of direst poverty. Your true son of the Tuscan mountains looks at the bright side of everything; a child in love, a demon in hatred, over-cautious with strangers, but easy and tractable in everything. I chatted to him for some twenty minutes, at the end of which time I resolved that he should assist me further in my investigations.

I told him how I had only arrived from Italy a few hours ago, and he grew at once excited. My train had actually passed across the rippling Serchio within a few miles of Ponte Moriano, his own village! I told him of my long residence in Tuscany, a fact which attracted him towards me; for seldom your poor Italian of the curb becomes acquainted with an Englishman who understands his ways and his language. And when I explained that I wished him to assist me in a very important and secret undertaking he at once announced his readiness to do so.

“Very well,” I said, giving him the half-sovereign I had promised. “Go across to the public-house in Theobald’s Road and get some supper quickly, for I want you to remain on watch here all night. I must rest and sleep for a few hours; but we must ascertain who goes and comes here. Above all, we must follow anyone carrying a parcel. A book was stolen from me in Italy, and it has been taken there.”

“I quite understand,” was his response; and a few moments later he left me alone while he went to obtain something to eat.
