“Then it was romantic, after all?”

“Oh, no, it wasn’t. I am sometimes inclined to think that nothing ever is. But I thought it was romantic. I was as bad in that respect as you are. He had something on his mind, which he wished to tell me. He was to leave the hospital next day—I could not go to see him, nor would it be safe for him to call at my house. I had servants who knew him. He gave me the name of one of them, and quite correctly too. I have no idea how he got hold of it. Would I give him a meeting one evening in the Square garden? What he had to tell me was a matter of life and death. It was a matter, in fact, that concerned the life of the greatest in the land. He was most urgent and most serious. If it were found out that he had betrayed the plot his own life would be forfeited. I told him that luckily I was in the habit of walking in the Square garden on fine summer evenings. I am inclined to think that he knew this already. I would go to the summer-house in the middle of the garden, and half an hour later he might join me there, coming in from the other side of the Square. Well, he came.”

“Wasn’t it very rash of you?”

“Very likely. I may be a lot of other things, but I am not a funk. I carried a useful weapon—it was not a dagger or revolver, but merely a police whistle. I was not in the least afraid of him. He kept it up splendidly to the very end. He told me a long and beautiful story, illustrated by plans of Buckingham Palace. The plans looked quite all right, but no woman can understand plans, and my knowledge of the interior of Buckingham Palace is very limited. He accepted ten sovereigns, under protest, to enable him to get out of the country. As I left the summer-house he helped me on with my cloak. That was his opportunity. I did not discover the loss until I got back to my own house. Even then, when I felt certain that he had stolen my necklace, I could not quite bring myself to disbelieve his story. It was so circumstantial, so full of details, so correct in every point in which I was able to check it. I drove at once to Scotland Yard, and it was not till I was actually there that I made up my mind to say nothing about my Italian friend and his story. I dreaded the courteous smile of an inspector who could put his hand at any time on any Anarchist in London. I merely notified them that I had lost the pearl necklace and gave a description of it. I wished to recover it and to let my cook friend go scot-free—not on his own account, but because I could not bear that my friends should know what an idiot I had made of myself.”

“And what about that servant who knew the Italian?”

“Simplicity itself. He did not know the Italian, nor did the Italian know him. The Italian merely knew that I employed a man of that name. Naturally, one of the first things I did was to satisfy myself on that point. Really, do you know, when I remember how my advertisement was worded, it seems to me that you have earned the reward. Won’t you let me write that cheque?”

“Thanks, very much,” I said, “but I’m afraid I don’t feel as if I’ve earned it myself. And so I can’t take it. I am sorry to have wasted your time with my mistakes.” I held out my hand to say good-bye.

She glanced at the clock nervously. “But you mustn’t go yet—not until you have seen the pearls.” She rang and had the necklace brought to her. It was just an ordinary necklace, and I could not imagine why she had bothered about it. I admired it and again said good-bye.

“But you must stay and have some tea with me. I am quite alone, and it would be so kind of you. I want you to tell me all about this marvellous memory of yours. I would give anything if I could cultivate it in myself.” Once more she glanced at the clock.

It was quite obvious, for some reason which I could not discover, that she was trying to keep me. I was determined to go. She implored me to wait at any rate until her carriage could be brought round to drive me back. She could not bear to think of the amount of trouble I had taken for her, an entire stranger to me. I might at least let her carriage take me home. But I immediately determined to walk. She still tried one or two frantic excuses for keeping me, but I was firm, and a minute or two later I was outside in the Square. I walked round to the other side of it, and there, in the Square garden, pacing up and down, was a man of about forty, of a foreign appearance, wearing a dark suit, a dark blue overcoat with a velvet collar, and a hard felt hat.
