In these circumstances, judge of my feelings when, shortly after the premature discovery termed in the press “the Oritoga mystery,” Mr. Addison one day presented himself at the Bell House!  His avowed intention of calling upon Lady Coverly left me no alternative.  Never in all his days, not even when he miraculously escaped the L.K.  Vapor at the Abbey Inn, did Mr. Addison stand so near to death as there—­in my study!

Let me explain the situation more fully.  The fatal Sothic month which I have learned to regard with horror, commenced on the twenty-third ultimo and does not terminate for another five days.  Nahemah was—­and still remains—­“possessed.”  You will understand my employment of the term.

On the night preceding this visit of Mr. Addison’s, I had traced her nocturnal movements by the howling of many dogs, and fearful of some indiscretion which might place my neck in a noose, I had followed her.  I found her in a narrow footpath which leads to the Abbey Inn!

Despite entreaties, threats, she declined to give any explanation of her behavior.  But finally I prevailed upon her to return to the Bell House.  The appearance of Mr. Addison on the following morning opened my eyes to the truth.  With the scandal still attaching to the names of Edward Hines and another man, called, I believe, Adams, a subject for gossip throughout the neighborhood, I could not at so perilous a time risk the consequences of a third intrigue.  I determined that Mr. Addison could better be spared by the community than I. Nahemah’s next insanity—­an open visit to the Abbey Inn—­confirmed my opinion.

Thereupon I committed my first mistake.  Cassim, the Nubian mute, who had been in my service for many years, was formerly attached to a great household in Stambul.  I shall probably be understood.  I instructed him; and Mr. Addison very cleverly playing upon his superstitious nature, Cassim failed.

My time grows short.  I will touch upon my second folly of that night.  Long before, the possibility of firing a projectile from the tower of Friar’s Park into the upper front of the Abbey Inn had presented itself to me in the light of a feasible experiment.

Unaware that Inspector Gatton was watching me—­unaware that in my absence he had actually detected the presence of the gun upon the tower—­I played my last card ... and lost.

Cassim it was who detected the fact that police were watching the Bell House!  Cassim had failed me once.  I instructed him a second time.

I near the end of my statement.  Destruction of all my effects, of all evidence of my work, and, crowning tragedy, of every trace of a life’s research, was unavoidable.  Knowing that every railway station and port would be watched and that my marked personality could not hope to escape the vigilance of the authorities, I determined to make a bid for freedom by seeking the shelter of my villa in London.

Cassim systematically fired the Bell House ... and perished in the flames!  Under cover of the confusion which the conflagration occasioned, Nahemah and I succeeded in making our retirement by the gate opening on the Hainingham road.
