As to the arrest of John Mitton, the valet, it was a council of despair as an alternative to absolute inaction.  But no case could be sustained against him.  He had visited friends in Hammersmith that night.  The alibi was complete.  It is true that he started home at an hour which should have brought him to Westminster before the time when the crime was discovered, but his own explanation that he had walked part of the way seemed probable enough in view of the fineness of the night.  He had actually arrived at twelve o’clock, and appeared to be overwhelmed by the unexpected tragedy.  He had always been on good terms with his master.  Several of the dead man’s possessions—­notably a small case of razors—­had been found in the valet’s boxes, but he explained that they had been presents from the deceased, and the housekeeper was able to corroborate the story.  Mitton had been in Lucas’s employment for three years.  It was noticeable that Lucas did not take Mitton on the Continent with him.  Sometimes he visited Paris for three months on end, but Mitton was left in charge of the Godolphin Street house.  As to the housekeeper, she had heard nothing on the night of the crime.  If her master had a visitor he had himself admitted him.

So for three mornings the mystery remained, so far as I could follow it in the papers.  If Holmes knew more, he kept his own counsel, but, as he told me that Inspector Lestrade had taken him into him into his confidence in the case, I knew that he was in close touch with every development.  Upon the fourth day there appeared a long telegram from Paris which seemed to solve the whole question.

A discovery has just been made by the Parisian police [said the daily telegraph] which raises the veil which hung round the tragic fate of Mr. Eduardo Lucas, who met his death by violence last Monday night at Godolphin Street, Westminster.  Our readers will remember that the deceased gentleman was found stabbed in his room, and that some suspicion attached to his valet, but that the case broke down on an alibi.  Yesterday a lady, who has been known as Mme. Henri Fournaye, occupying a small villa in the Rue Austerlitz, was reported to the authorities by her servants as being insane.  An examination showed she had indeed developed mania of a dangerous and permanent form.  On inquiry, the police have discovered that Mme. Henri Fournaye only returned from a journey to London on Tuesday last, and there is evidence to connect her with the crime at Westminster.  A comparison of photographs has proved conclusively that M. Henri Fournaye and Eduardo Lucas were really one and the same person, and that the deceased had for some reason lived a double life in London and Paris.  Mme. Fournaye, who is of Creole origin, is of an extremely excitable nature, and has suffered in the past from attacks of jealousy which have amounted to frenzy.  It is conjectured that it was in one of these that
