“What!” Dr. Cumberly turned in his promenade and stared at the detective—“he's not the only one?”
“My dear sir,” said Max, gently, “the victims of Mr. King are truly as the sands of Arabia.”
“Good heavens!” muttered Dr. Cumberly; “good heavens!”
“I came immediately to London,” continued Max, “and presented myself at New Scotland Yard. There I discovered that my inquiry was complicated by a ghastly crime which had been committed in the flat of Mr. Leroux; but I learned, also, that Mr. King was concerned in this crime—his name had been found upon a scrap of paper clenched in the murdered woman's hand!”
“I was present when it was found,” said Dr. Cumberly.
“I know you were,” replied Max. “In short, I discovered that the Palace Mansions murder case was my case, and that my case was the Palace Mansions case. Eh bien! the mystery of the Paris draft did not detain me long. A call upon the manager of the London County and Suburban Bank at Charing Cross revealed to me the whole plot. The real Mrs. Leroux had never visited that bank; it was Madame Jean, posing as Mrs. Leroux, who went there and wrote the specimen signature, accompanied by a certain Soames, a butler”...
“I know him!” said Dr. Cumberly, grimly, “the blackguard!”
“Truly a blackguard, truly a big, dirty blackguard! But it is such canaille as this that Mr. King discovers and uses for his own ends. Paris society, I know for a fact; has many such a cankerworm in its heart. Oh! it is a big case, a very big case. Poor Mr. Leroux being confined to his bed—ah! I pity him—I took the opportunity to visit his flat in Palace Mansions with Inspector Dunbar, and I obtained further evidence showing how the conspiracy had been conducted; yes. For instance, Dunbar's notebook showed me that Mr. Leroux was accustomed to receive letters from Mrs. Leroux whilst she was supposed to be in Paris. I actually discovered some of those letters, and they bore no dates. This, if they came from a woman, was not remarkable, but, upon one of them I found something that WAS remarkable. It was still in its envelope, you must understand, this letter, its envelope bearing the Paris post-mark. But impressed upon the paper I discovered a second post-mark, which, by means of a simple process, and the use of a magnifying glass, I made out to be Bow, East!”
“What!”
“Do you understand? This letter, and others doubtless, had been enclosed in an envelope and despatched to Paris from Bow, East? In short, Mrs. Leroux wrote those letters before she left London; Soames never posted them, but handed them over to some representative of Mr. King; this other, in turn, posted them to Madame Jean in Paris! Morbleu! these are clever rogues! This which I was fortunate enough to discover had been on top, you understand, this billet, and the outer envelope being very heavily stamped, that below retained the impress of the post-mark.”
