The Mikado Jewel. Fergus Hume

again, for even in her poverty she shrank from taking money. "I don't like mysteries, and only accept your offer as I need money very badly. But for all the wealth in the world I would not go if I thought that there was anything wrong," and she looked searchingly at her companion.

      "How many times do you need me to assure you that there is nothing wrong," said Mrs. Pentreddle, impatiently; "you are singularly suspicious for a girl of your years. All that is necessary is for you to receive this tiny box from the man who will hand it to you."

      "How shall I know the man?"

      "There is no need for you to know him at all. The red light of the lantern will assure him that you are the person who is to receive the box. Well?"

      Miss Carrol rose nervously and ran her fingers through her hair, as she walked up and down the long room. Her instinct told her to refuse a mission about which she knew so little, but the prospect of earning five pounds in this easy manner was so alluring, that she could not find it in her heart to decline. After all, Mrs. Pentreddle was the sister of the woman who had been, and was, so kind to her, and in every way appeared to be an almost aggressively respectable person. It was worth risking, she thought, and at this moment, as though to clinch the matter, Mrs. Pentreddle's voice broke in on her uneasy meditations.

      "I can't wait much longer," said the old woman; "if you won't do what I ask, perhaps you will telephone to the nearest office, asking that a messenger-boy may be sent to get what I want. It will certainly be cheaper."

      This proposal banished Patricia's last scruple, as, if a messenger-boy could be employed, the errand, mysterious as it seemed, could not have anything to do with criminal matters. Miss Carrol picked up the lantern, with its faked red glass. "I shall go at once," she declared hurriedly, for now she feared lest she should lose the money, "but who will attend to your foot while I am away, Mrs. Pentreddle?"

      "I can stay here, as I am doing. Rest is the sole thing which can cure my sprain. You will only be away an hour, more or less. It is a quarter past eight now, and the distance to the Serpentine bridge is not far. Nine o'clock is the hour. You know exactly what you have to do," and she repeated her instructions, to which the girl listened carefully.

      "I am to show the red light standing on this side of the Serpentine at the right-hand corner of the bridge," she said slowly, to be sure that she knew what she had to do. "I understand. What shall I say to the man?"

      "Nothing. He will simply place a box in your hand and walk away. All you have to do is to bring the box to me, and then you shall know all about the matter which strikes you as being so strange. Don't lose any time, please."

      Indeed, there was no time to be lost, as it would take Patricia some minutes to get her out-of-door things on. She ran up the stairs, and assumed boots in place of slippers, a heavy cloak as the night was damp, a plain cloth toque, and gloves. She then took her umbrella in one hand, the lantern, unlighted, in the other, and descended to say a few last words to Mrs. Pentreddle; or, rather, to hear them, for the old lady gave her no opportunity of speaking. For such a grim, unemotional woman, Mrs. Pentreddle seemed quite excited, although she tried to keep herself calm. But a vivid spot of red was certainly showing itself on either pale cheek.

      "Show the red light and wait in silence," she directed; "do nothing more, and say nothing at all. Then when you receive the box come back with it at once to me. You thoroughly understand?"

      "I thoroughly understand."

      "I am glad. Finally, let me assure you once more that there is nothing dishonest or even wrong about the errand I am sending you on."

      There was nothing more to be said, and Patricia departed. When she closed the front door of The Home of Art, and found herself in the street, she became aware that the night was damp and dense with fog. The gas-lights, however, shone blurred and vague through the white mists, so there was no need for her to use the lantern. No one was about, not even a policeman--in the curve of the cul de sac at all events; but when she passed into the straight line of Crook Street, she almost fell into the arms of a constable who was standing under a lamp. Patricia paused to ask a question.

      "Will the fog get worse, officer?"

      "I think it will, miss," said the man, touching his helmet and bending to look at her face. "I should advise you not to go far."

      "I am only going to the Park to see a friend," answered Miss Carrol, heedlessly; and then remembering that it was a complete stranger whom she had to see, and one to whom she was not even to speak, she regretted having been so doubtfully truthful. "What is the time?" she asked, to cover her confusion.

      "Half-past eight o'clock, miss," said the constable, consulting a fat silver watch. "Best go home again, miss. You might get lost in this fog, and in the Park there are some rough characters about."

      "Oh, I am all right, thank you," said Patricia with a bright smile, and passed along. All the same she now began to feel uncomfortable, and to realize that Hyde Park on a foggy November night was not exactly the place for a young lady. Only the desire to earn the coveted five pounds nerved her to do that which she had agreed to do.

      Crook Street is not far from the main entrance to the Park on the Bayswater side, and, as the fog grew thin further on, Patricia found herself speedily on the broad path which leads directly to the Serpentine bridge. She knew this portion of the Park extremely well, as, having much time on her hands, she frequently wandered about the grassy spaces on idle afternoons. There were few people about, as the night was so disagreeable, and those she saw moved swiftly past her. Occasionally she caught a glimpse of vague forms under the trees: but she never looked closely at these night-prowlers, but, keeping in the middle of the path, moved steadily to her destination. At last she came to the bridge and took up her station at the right-hand corner on this near side. Having come to the end of her journey she lighted the lantern.

      Across the water the broad bridge stretched weirdly, vanishing into the fog, which here grew denser, like the Bridge of Life in the Vision of Mirza. Patricia had read Addison's fantastic story in some school-book, and it was suggested to her again by the sight before her. People came out of the mist and disappeared into it again: some passed, unconscious of the quiet figure at the corner, while others peered into her face. But no one addressed her, much to her relief, and the ruddy light of her lantern shone like an angry star. Then the expected happened in one moment and quite without preparation.

      A man came swiftly over the bridge--so swiftly, that it might have been said that he was running. She had no time to see what he was like in looks, or how he was dressed, before he caught sight of the red light and stopped for one moment to thrust a small box into her hand. Then he darted away to the left and disappeared along the bank on the Bayswater side. That was all!

       CHAPTER II

      WHAT HAPPENED

      For some moments Patricia stood still, with the box in her hand, and stared into the gloomy fog, behind which the man was retreating. Another man passed her swiftly, as if in pursuit of the first, but halted for one single moment to look at her. She was an indistinct figure in the misty air, but she could feel that his eyes were piercing her through and through. A few seconds later and he disappeared also, but whither he went she could not tell. The whole oddity of the episode startled her, although much that had taken place had been anticipated and described by Mrs. Pentreddle.

      As the name flashed across Miss Carrol's brain, she remembered that she had yet to complete her mission by taking back the box to the old lady. Almost mechanically, and with the lantern still burning, she began to retrace her steps in the direction of Bayswater. The fog was growing denser, but by her knowledge of the path and the feel of the hard gravel under her feet, she was enabled to avoid getting lost. A sudden sense of weariness, which no doubt came from the slackening of her nervous tension, overcame her, and she was glad to sink down on the first bench she came to. This was near a gas-lamp, and in the blurred circle of light she felt safe from the attentions of any night-bird. Then a strange thing happened.

      It was a sensation and nothing more: one connected
