“They appear to be in high feather just now,” I remarked.

“Yes: they are connected, I suspect, with the gang who cleaned out young Garslade last week in Jermyn Street. I’d lay a trifle,” added my friend, as I turned to leave him, “that one or both of them will wear the queen’s livery gray turned up with yellow, before many weeks are past. Good-by.”

About a fortnight after this conversation, I and my wife paid a visit to Astley’s, for the gratification of our youngsters, who had long been promised a sight of the equestrian marvels exhibited at that celebrated amphitheatre. It was the latter end of February; and when we came out of the theatre, we found the weather had changed to dark and sleety, with a sharp, nipping wind. I had to call at Scotland-Yard; my wife and children consequently proceeded home in a cab without me; and after assisting to quell a slight disturbance originating in a gin-palace close by, I went on my way over Westminster Bridge. The inclement weather had cleared the streets and thoroughfares in a surprisingly short time; so that, excepting myself, no foot-passenger was visible on the bridge till I had about half-crossed it, when a female figure, closely muffled up about the head, and sobbing bitterly, passed rapidly by on the opposite side. I turned and gazed after the retreating figure: it was a youthful, symmetrical one; and after a few moments’ hesitation, I determined to follow at a distance, and as unobservedly as I could. On the woman sped, without pause or hesitation, till she reached Astley’s, where I observed her stop suddenly, and toss her arms in the air with a gesture of desperation. I quickened my steps, which she observing, uttered a slight scream, and darted swiftly off again, moaning and sobbing as she ran. The slight momentary glimpse I had obtained of her features beneath the gaslamp opposite Astley’s, suggested a frightful apprehension, and I followed at my utmost speed. She turned at the first-cross street, and I should soon have overtaken her, but that in darting round the corner where she disappeared, I ran full butt against a stout, elderly gentleman, who was hurrying smartly along out of the weather. What with the suddenness of the shock and the slipperiness of the pavement, down we both reeled; and by the time we had regained our feet, and growled savagely at each other, the young woman, whoever she was, had disappeared, and more than half an hour’s eager search after her proved fruitless. At last I bethought me of hiding at one corner of Westminster Bridge. I had watched impatiently for about twenty minutes, when I observed the object of my pursuit stealing timidly and furtively towards the bridge on the opposite side of the way. As she came nearly abreast of where I stood, I darted forward; she saw, without recognising me, and uttering an exclamation of terror, flew down towards the river, where a number of pieces of balk and other timber were fastened together, forming a kind of loose raft. I followed with desperate haste, for I saw that it was indeed Mary Kingsford, and loudly calling to her by name to stop. She did not appear to hear me, and in a few moments the unhappy girl had gained the end of the timber-raft. One instant she paused with clasped hands upon the brink, and in another had thrown herself into the dark and moaning river. On reaching the spot where she had disappeared, I could not at first see her in consequence of the dark mourning dress she had on. Presently I caught sight of her, still upborne by her spread clothes, but already carried by the swift current beyond my reach. The only chance was to crawl along a piece of round timber which projected farther into the river, and by the end of which she must pass. This I effected with some difficulty; and laying myself out at full length, vainly endeavored, with out-stretched, straining arms, to grasp her dress. There was nothing left for it but to plunge in after her. I will confess that I hesitated to do so. I was encumbered with a heavy dress, which there was no time to put off, and moreover, like most inland men, I was but an indifferent swimmer. My indecision quickly vanished. The wretched girl, though gradually sinking, had not yet uttered a cry, or appeared to struggle; but when the chilling waters reached her lips, she seemed to suddenly revive to a consciousness of the horror of her fate: she fought wildly with the engulphing tide, and shrieked piteously for help. Before one could count ten, I had grasped her by the arm, and lifted her head above the surface of the river. As I did so, I felt as if suddenly encased and weighed down by leaden garments, so quickly had my thick clothing and high boots sucked in the water. Vainly, thus burdened and impeded, did I endeavor to regain the raft; the strong tide bore us outwards, and I glared round, in inexpressible dismay, for some means of extrication from the frightful peril in which I found myself involved. Happily, right in the direction the tide was drifting us, a large barge lay moored by a chain-cable. Eagerly I seized and twined one arm firmly round it, and thus partially secure, hallooed with renewed power for assistance. It soon came: a passer-by had witnessed the flight of the girl and my pursuit, and was already hastening with others to our assistance. A wherry was unmoored: guided by my voice, they soon reached us; and but a brief interval elapsed before we were safely housed in an adjoining tavern.

A change of dress, with which the landlord kindly supplied me, a blazing fire, and a couple of glasses of hot brandy and water, soon restored warmth and vigor to my chilled and partially benumbed limbs; but more than two hours elapsed before Mary, who had swallowed a good deal of water, was in a condition to be removed. I had just sent for a cab, when two police-officers, well known to me, entered the room with official briskness. Mary screamed, staggered towards me, and clinging to my arm, besought me with frantic earnestness to save her.

“What is the meaning of this?” I exclaimed, addressing one of the police-officers.

“Merely,” said he, “the young woman that’s clinging so tight to you has been committing an audacious robbery”——

“No—no—no!” broke in the terrified girl.

“Oh! of course you’ll say so,” continued the officer. “All I know is, that the diamond brooch was found snugly hid away in her own box. But come, we have been after you for the last three hours; so you had better come along at once.”

“Save me!—save me!” sobbed poor Mary, as she tightened her grasp upon my arm and looked with beseeching agony in my face.

“Be comforted,” I whispered; “you shall go home with me. Calm yourself, Miss Kingsford,” I added in a louder tone: “I no more believe you have stolen a diamond brooch than that I have.”
