In her own private sitting-room, a cosy little apartment overlooking Piccadilly, opposite Dover Street, she removed her big black hat, drew off her gloves, and having invited me to a chair, took one herself on the opposite side of the fireplace. Her maid was there when we entered, but retired at word from her mistress.
“You, of course, regard it as very curious, Mr Heaton, that after these six years I should again seek you,” she commenced, leaning her arm lightly upon the little table, and gazing straight into my face without flinching. “It is true that once I was enabled to render you a service, and now in return I ask you also to render me one. Of course, it is useless to deny that a secret exists between us—a secret which, if revealed, would be disastrous.”
“To whom?”
“To certain persons whose names need not be mentioned.”
“Why not?”
“Think,” she said, very gravely. “Did you not promise that, in return for your life when you were blind and helpless, you would make no effort to learn the true facts? It seems that you have already learnt at least one—the spot where the crime was committed.”
“I consider it my duty to learn what I can of this affair,” I answered determinedly.
She raised her eyebrows with an expression of surprise, for she saw that I was in earnest.
“After your vow to me?” she asked. “Remember that, to acknowledge my indebtedness for that vow, I searched for the one specialist who could restore your sight. To my efforts, Mr Heaton, you are now in possession of that sense that was lost to you.”
“I acknowledge that freely,” I answered. “Yet, even in that you have sought to deceive me.”
