Lord John in New York. Williamson Charles Norris

that she had openly visited the Tostinis at their small villa between Posilipo and Naples. The family had also called and dined at her hotel, where they were not unknown. After that their circumstances had apparently improved, and it appeared not improbable that Marian Callender had helped her late lover's people.

      When she returned to New York it was to find that Grace was being bombarded with love letters at school, and that the hotel in the village near by had for its principal clients a crowd of young men whose whole business in life was lying in wait for the heiress. In consequence, Marian brought her niece back to the house in Park Avenue; and soon after, before the girl had been allowed to come out in society, Antonio, the younger brother of Paolo Tostini, arrived in New York. His business was that of an analytical chemist. He had first-rate recommendations, and was an extremely brilliant, as well as singularly good-looking young man, some (who remembered the tenor) thought even handsomer than Paolo. Antonio Tostini, thanks to his own ability and the introductions he had from Miss Callender and others, got on well both in business and society. No one was surprised, and no one blamed her, when Marian Callender threw the clever young Italian and Grace Callender together – except that the girl was young to make up her mind, and her dead father had favoured a match with one of the disinherited cousins.

      From these rough notes, crudely classifying Antonio Tostini's courtship of Grace Callender, I gathered that the young Italian had fallen desperately in love with the girl. He had assured friends whom they had in common that even if, to marry him, she were obliged to give up her fortune, he would still think himself the happiest man on earth to win her. Grace's aunt, who had tried to keep the girl out of other men's way, evidently favoured her old love's brother. She chaperoned a yachting party, of which Grace and Antonio were the most important members, a party in which the Callender-Grahams were not included, though they wished for invitations. This match-making effort on Marion's part stifled all suspicion that she discouraged Grace from marrying in order to retain a charming home, a large, certain income, and all kinds of other luxuries for herself. She had taken Grace's refusal of Antonio Tostini almost as hard as he had taken it himself. She had even been ill for several weeks when for the third time Grace had sent him away, and he returned in despair to Italy. It was not long after this affair (the dossier informed me) that, in accordance with her father's desire, the girl engaged herself to Perry Callender-Graham, and Marian consented to the inevitable. Her affection and support during the tragic experiences that followed had given great comfort to Grace, and, so far as was known, Antonio Tostini had had the good taste never to appear on the scene again.

      Here were many details which I had been anxious, but not decently able, to learn, as the Misses Callenders' shipboard friendship had confined itself to lending me books, telling me what to do in New York, inviting me to call, listening to talk about the war or the play, and allowing me to snapshot them on deck.

      Having looked through the dossier, I took my departure with the key. It was only a duplicate, yet I couldn't rid myself of a queer, superstitious feeling for the thing, as if it were offered to me by the unseen hand of a dead man.

      I taxied back to my hotel and mentioned to a clerk that I wanted to see houses and flats in the direction of Riverside Drive. Could he direct me to an agent who would have the letting of apartments in that neighbourhood? If my foreign way of expressing myself amused him, he hid his mirth and looked up in a big book the addresses of several agents.

      I had not cared to be too specific in my questions, but I chose the address nearest the street I wanted, taxied there, found the agent, and inquired if there were anything to be let. It was the street in which Perry Callender-Graham and Ned, his brother, had met their death.

      "I have been recommended to that particular street by an American friend in England," I said. "He has told me that it's very quiet. There are several apartment houses in it, are there not?

      "Yes," replied a spruce young man who looked willing to let me half residential New York. "But it's a favourite street; I'm afraid there's nothing doing there now. As for houses, they're all owned, or have been rented for many years. A little farther north or south – "

      "Hold on," I pulled him back. "Somebody might be induced to let. My friend was telling me about a charming flat – oh, apartment you call it? – in that street which a friend of his took – let me see, it must have been three years ago or thereabouts. Anyhow, not later. He had reason to believe I might get that very flat. Stupid of me! I can't remember the number or name – whichever it was – of the house. I know the flat was a furnished one, however; and if your agency – "

      "Oh, if the apartment was furnished, and changed hands three years ago, there's only one it could be, if you're sure it's in that street?"

      "I'm sure," I replied. I staked all on that sureness, though logically – But I would not let my mind wander to any other deduction than the one to which, for better or worse, I pinned my faith.

      "We had the letting of a furnished apartment in the Alhambra, as the house is named, put into our hands three years ago on the 30th of last month," said the youth, referring to a book. "To my certain knowledge no other furnished one was to be had in the street at that time, and there hasn't been since. Isn't likely to be either, so far as I can see. That was the grand chance. German-American lady and gentleman, Mr. and Mrs. Maurice Lowenstein, going unexpectedly to Europe, and glad to get rid of their apartment to a good tenant at a nominal price."

      "You found the good tenant?" I asked.

      "We did, sir – or the tenant found us. Wanted a furnished apartment, not too large or expensive, in a quiet street, quietness the great consideration. Above all, the proprietors mustn't want to use the place again for at least five years. That just fitted in, because our clients were anxious to let for seven years; the husband had a business opening in Hamburg. The new tenant took the place for that period; and as there's a long time to run yet, I shouldn't have thought there was much hope for you. However, your friend may have private information."

      "Does the new tenant live there altogether?" I wanted to know.

      "Only comes up from the country occasionally. Expensive fad, to rent a New York apartment that way. But what's money for? Some people have it to burn."

      "Quite so," I admitted. "Have you ever met the tenant?"

      "Only once – when the apartment was engaged; fixed up in one interview. The rent comes through the post."

      "It must be the apartment my friend talked about!" I exclaimed.

      "Can't be any other. Is the name of your friend's friend Paulling?"

      "Why, yes, I have the impression of something like that. By the way, I might be able to find an old photograph, to make quite sure. Would you recognise it?"

      "I might – and I mightn't. Three years is a long time."

      "Well, I'll do my best through some acquaintances," I finished. "If we're speaking of the same person, you may be able to introduce me and save the delay of communicating with my friend in England."

      Each was flattering himself on his discretion, the whole catechism having been gone through without the question on either side, "Is the person a man or a woman?" Eventually we parted with the understanding that I should return later if, after looking at the Alhambra from the outside, I fancied it as much as I expected to do. And then I was to bring the photograph with me.

      So far so good. But the next steps were not so simple.

      I stopped my taxi at the corner (not to advertise myself with unnecessary noise) and limped the short distance which Perry Callender-Graham and his brother Ned must have travelled on the secret errands that led them to their death. The Alhambra was neither as picturesque nor as imposing as its name suggested. It was just a substantial brick building, six or seven storeys in height, with facings of light-coloured stone, and large, cheerful windows. Luckily for my lame leg, the entrance was but a step above the street level. As I arrived the door was opened by a chocolate-brown negro in chocolate-brown livery. He helped a smart nurse to pass out with a baby in a white and gold chariot, and while he was thus engaged I hobbled into the hall. A hasty glance at a name board on the wall opposite gave me the list of occupants and the floor on which each tenant lived. Evidently there were two flats to each storey. T. Paulling had an apartment on the third,
