"I beg pardon," he quietly finished. "If it is Georgian, she must stand my friend. That is all I was going to say. If it is, against all reason and probability, her strangely restored twin, I shall leave this house by midnight, never probably to see any of you again. So you perceive that it is incumbent upon us to work promptly. Are you ready to hear what I have to propose?"

"Yes."

Hazen paused again, this time in front of the door. Laying his hand lightly on one of the panels, he glanced back at Ransom.

"You are nicely placed here for observation. Your door directly faces the hall she must traverse in returning to her room."

"That's quite true."

"She's in her room now. Ah, you know that?"

"Yes." Ransom seemed to have no other word at his command.

"Will she come out again before night to eat or to visit?"

"There's no telling. She's very fitful. No one can prophesy what she will do. Sometimes she eats in the landlady's room, sometimes in her own, sometimes not at all. If you have frightened her, or she has been disturbed in any way by your companion who shows such interest in her and in me, she probably will not come out at all."

"But she must. I expect you to see that she does. Use any messenger, any artifice, but get her away from this hall for ten minutes, even if it is only into Mrs. Deo's room. When she returns I shall be on my knees before this keyhole to watch her and observe. To see what, I do not mean to tell you, but it will be something which will definitely settle for me this matter of identity. Does this plan look sufficiently harmless to meet with your approval?"
