Roonah had come over to England ready to swear that her sister had died in her arms two months after the birth of Captain Duplessis’s eldest child, and there was the sworn testimony of Dr. Rénaud, since dead. These affidavits Mr. McKinley had seen and read.
Against that, the only proof which now remained of the justice of Joan Duplessis’s claim was the fact that her mother and father went through a second form of marriage some time after the birth of their first child, Henriette. This fact was not denied, and, of course, it could be easily proved, if necessary, but even then it would in no way be conclusive. It implied the presence of a doubt in Captain Duplessis’s mind, a doubt which the second marriage ceremony may have served to set at rest; but it in no way established the illegitimacy of his eldest daughter.
In fact, the more Mr. McKinley spoke, the more convinced did everyone become that the theft of the papers had everything to do with the murder of the unfortunate Roonah. She would not part with the proofs which meant her mistress’s fortune, and she paid for her devotion with her life.
Several more witnesses were called after that. The servants were closely questioned, the doctor was recalled, but, in spite of long and arduous efforts, the coroner and jury could not bring a single real fact to light beyond those already stated.
The Indian woman had been murdered!
The papers which she always carried about her body had disappeared.
Beyond that, nothing! An impenetrable wall of silence and mystery!
The butler at Fordwych Castle had certainly missed the knife with which Roonah had been killed from its accustomed place on the morning after the murder had been committed, but not before, and the mystery further gained in intensity from the fact that the only purchase of chloroform in the district had been traced to the murdered woman herself.
She had gone down to the local chemist one day some two or three weeks previously, and shown him a prescription for cleansing the hair which required some chloroform in it. He gave her a very small quantity in a tiny bottle, which was subsequently found empty on her own dressing-table. No one at Fordwych Castle could swear to having heard any unaccustomed noise during that memorable night. Even Joan, who slept in the room adjoining that where the unfortunate Roonah lay, said she had heard nothing unusual. But then, the door of communication between the two rooms was shut, and the murderer had been quick and silent.
Thus this extraordinary inquest drew to a close, leaving in its train an air of dark suspicion and of unexplainable horror.
