According to A Day by Day Chronology of Mr Sherlock Holmes, According to Zeisler and Christ, compiled and edited by William S Dorn, BSI and DWNP, on June 4, 1902, Holmes confronted Isadora Klein. [3GAB]
A minute later we were in an Arabian Nights’ drawing-room, vast and wonderful, in a half gloom, picked out with an occasional pink electric light. The lady had come, I felt, to that time of life when even the proudest beauty finds the half-light more welcome. She rose from a settee as we entered; tall, queenly, a perfect figure, a lovely mask-like face, with two wonderful Spanish eyes which looked murder at us both.
“In the first place you must give back this manuscript.”
She broke into a ripple of laughter, and walked to the fireplace. There was a calcined mass which she broke up with the poker. “Shall I give this back?” she asked. So roguish and exquisite did she look as she stood before us with a challenging smile that I felt of all Holmes’s criminals this was the one whom he would find it hardest to face. However, he was immune from sentiment.
“That seals your fate,” he said coldly. “You are very prompt in your actions, madame, but you have overdone it on this occasion.”
