It commenced:

“Copy of an ‘information’ in the archives of the Prefecture of the Department of Herault concerning the woman Marie Mignot, or Leullier, now passing under the name of Yvonne Ferad and living at the Villa Amette at Monte Carlo.

“The woman in question was born in 1884 at Number 45 Rue des Etuves, in Montpellier, and was the daughter of one Doctor Rigaud, a noted toxicologist of the Faculty of Medicine, and curator of the University Library. At the age of seventeen, after her father’s death, she became a school teacher at a small school in the Rue Morceau, and at nineteen married Charles Leullier, a good-looking young scoundrel who posed as being well off, but who was afterwards proved to be an expert international thief, a member of a gang of dangerous thieves who committed robberies in the European express trains.

“This fact was unknown to the girl, therefore at first all went smoothly, until the wife discovered the truth and left him. She then joined the chorus of a revue at the Jardin de Paris, where she met a well-to-do Englishman named Bryant. The pair went to England, where she married him, and they resided in the county of Northampton. Six months later Bryant died, leaving her a large sum of money. In the meantime Leullier had been arrested by the Italian police for a daring robbery with violence in a train traveling between Milan and Turin and been sentenced to ten years on the penal island of Gorgona. His wife, hearing of this from an Englishman named Houghton, who, though she was unaware of it, was following the same profession as her husband, returned to France. She rented an apartment in Paris, and afterwards played at Monte Carlo, where she won a considerable sum, with the proceeds of which she purchased the Villa Amette, which she now occupies each season.”

“Extracts of reports concerning Marie Leullier, alias Yvonne Ferad, are herewith appended:

“Criminal Investigation Department, New Scotland Yard, London—to the Prefecture of Police, Paris.

“Mademoiselle Yvonne Ferad rented a furnished house at Hove, near Brighton, in June, 1918. Afterwards moved to Worthing and to Exeter, and later took a house in the Cromwell Road, London, in 1919. She was accompanied by an Italian manservant named Cataldi. Her conduct was suspicious, though she was undoubtedly possessed of considerable means. She was often seen at the best restaurants with various male acquaintances, more especially with a man named Kenworthy. Her association with this person, and with another man named Percy Stendall, was curious, as both men were habitual criminals and had served several terms of penal servitude each. Certain suspicions were aroused, and observation was kept, but nothing tangible was discovered. It is agreed, however, that some mystery surrounds this woman in question. She left London quite suddenly, but left no debts behind.”

“Information from the Borough Police Office, Worthing, to the Prefecture of Police, Department of Herault.

“Mademoiselle Yvonne Ferad has been identified by the photograph sent as having lived in Worthing in December, 1918. She rented a small furnished house facing the sea, and was accompanied by an Italian manservant and a French maid. Her movements were distinctly mysterious. A serious fracas occurred at the house on the evening of December 18th, 1918. A middle-aged gentleman, whose name is unknown, called there about seven o’clock and a violent quarrel ensued between the lady and her visitor, the latter being very seriously assaulted by the Italian. The constable on duty was called in, but the visitor refused to prosecute, and after having his injuries attended to by a doctor left for London. Three days later Mademoiselle disappeared from Worthing. It is believed by the Chief Constable that the woman is of the criminal class.”

Then Charles Ogier, inspector of the detective police of Monaco, smiled, laid down his cigar, and took up another and even more interesting document.
