“Not the man whom you know as Ashwicke, but another,” she responded. “He was interested in the occult sciences, apparently wealthy, and much enamoured of me. In the six months of our courtship I learned to love him madly, and the result was that we were married at the Municipio, in Milan, which stands exactly opposite the entrance to the theatre. A month afterwards, however, he decamped with my jewels and the whole of the money I had saved, leaving behind him, as his only personal possessions, a box containing some rare old vellum books which he had purchased somewhere down in the old Tuscan towns, and of which he had been extremely careful. At first I could not believe that he could have treated me thus, after all his professions of love; but as the weeks passed and he did not return, I slowly realised the truth that I had been duped and deserted. It was then that I made a vow of revenge.

“Ten endless years passed, and, my personal beauty having faded, I was compelled to remain on the stage, accepting menial parts and struggling for bread until, by the death of a cousin, I found myself with sufficient to live upon. Though I had no clue to who my husband was, beyond a name which had most probably been assumed, I nevertheless treasured his books, feeling vaguely that some day they might give me a clue. In those years that went by I spent days and days deciphering the old black letters, and translating from the Latin and Italian. They were nearly all works dealing with the ancient practice of medicine, but one there was dealt with secret poisons. I have it here;” and unlocking a drawer in a rosewood cabinet, she took therefrom a big leather-covered tome, written in Latin upon vellum.

There was an old rusted lock of Florentine workmanship upon it, and the leather was worm-eaten and tattered.

“This contains the secret of the vayana,” she went on, opening the ponderous volume before me upon the table. “I discovered that the poison was the only one impossible of detection, and then it occurred to me to prepare it, and with it strike revenge. Well, although I had been in London a dozen times in search of the man I had once loved, I came again and settled down here, determined to spare no effort to discover him. Through four whole years I sought him diligently, when at last I was successful. I discovered who and what he was.”

“Who was he?” I inquired.

“The man you know as Major Tattersett. His real name is Ashwicke.”

“Tattersett?” gasped Beryl. “And he is your husband?”

“Most certainly,” she responded. “I watched him diligently for more than twelve months, and discovered that his career had been a most extraordinary one, and that he was in association with a man named Graham—who sometimes also called himself Ashwicke—and who was one of the most expert and ingenious forgers ever known. Graham was a continental swindler whom the police had for years been endeavouring to arrest, while the man who was my husband was known in criminal circles as ‘The Major.’ Their operations in England, Belgium, and America were on a most extensive-scale, and in the past eight years or so they have amassed a large fortune, and have succeeded in entering a very respectable circle of society. While keeping watch upon my husband’s movements, I found that he, one evening a few months ago, went down to Hounslow, and, unobserved by him, I travelled by the same train. I followed him to Whitton, and watched him meet clandestinely a lady who was one of the guests.”

“It was myself?” Beryl exclaimed, standing utterly dumbfounded by these revelations.

“Yes,” the woman went on. “I was present at your meeting, although not sufficiently near to overhear your conversation. By your manner, however, I felt confident that you were lovers, and then a fiendish suggestion—one that I now deeply regret—occurred to me, namely to kill you both by secret means. With that object I went to the small rustic bridge by the lake—over which I knew you must pass on your return to the house, both of you having crossed it on your way there—and upon the hand-rail I placed the poison I had prepared. I knew that if you placed your hand upon the rail the poison would at once be absorbed through the skin, and must prove fatal. My calculations were, however, incorrect, for an innocent man fell victim. Colonel Chetwode came down that path, and, unconsciously grasping the rail, received the sting of death, while you and your companion returned by a circuitous route, and did not therefore discover him.”
