And now there was one sane person in the house, for I had regained complete command of my thoughts.  Working in a logical succession of images they showed me at last as clearly as a picture on a wall, Therese pressing with fervour the key into the fevered palm of the rich, prestigious, virtuous cousin, so that he should go and urge his self-sacrificing offer to Rita, and gain merit before Him whose Eye sees all the actions of men.  And this image of those two with the key in the studio seemed to me a most monstrous conception of fanaticism, of a perfectly horrible aberration.  For who could mistake the state that made Jose Ortega the figure he was, inspiring both pity and fear?  I could not deny that I understood, not the full extent but the exact nature of his suffering.  Young as I was I had solved for myself that grotesque and sombre personality.  His contact with me, the personal contact with (as he thought) one of the actual lovers of that woman who brought to him as a boy the curse of the gods, had tipped over the trembling scales.  No doubt I was very near death in the “grand salon” of the Maison Doree, only that his torture had gone too far.  It seemed to me that I ought to have heard his very soul scream while we were seated at supper.  But in a moment he had ceased to care for me.  I was nothing.  To the crazy exaggeration of his jealousy I was but one amongst a hundred thousand.  What was my death?  Nothing.  All mankind had possessed that woman.  I knew what his wooing of her would be:  Mine—­or Dead.

All this ought to have had the clearness of noon-day, even to the veriest idiot that ever lived; and Therese was, properly speaking, exactly that.  An idiot.  A one-ideaed creature.  Only the idea was complex; therefore it was impossible really to say what she wasn’t capable of.  This was what made her obscure processes so awful.  She had at times the most amazing perceptions.  Who could tell where her simplicity ended and her cunning began?  She had also the faculty of never forgetting any fact bearing upon her one idea; and I remembered now that the conversation with me about the will had produced on her an indelible impression of the Law’s surprising justice.  Recalling her naive admiration of the “just” law that required no “paper” from a sister, I saw her casting loose the raging fate with a sanctimonious air.  And Therese would naturally give the key of the fencing-room to her dear, virtuous, grateful, disinterested cousin, to that damned soul with delicate whiskers, because she would think it just possible that Rita might have locked the door leading front her room into the hall; whereas there was no earthly reason, not the slightest likelihood, that she would bother about the other.  Righteousness demanded that the erring sister should be taken unawares.

All the above is the analysis of one short moment.  Images are to words like light to sound—­incomparably swifter.  And all this was really one flash of light through my mind.  A comforting thought succeeded it:  that both doors were locked and that really there was no danger.
