"Here you are, blocking the corridor at Number Four"; he made a mark on the
plan at that point. "By the way, are there any other exits from the banquet
room except these two corridor doors?"

"No, sir."

"Good! Now pay attention. While you were listening at this door--I'll mark
it _A_--with your back turned to Number Six, a person _might_ have left the
banquet room by the farther door--I'll mark it _B_--and stepped across the
corridor into Number Six without your seeing him. Isn't that true?"

"Yes, sir, it's possible."

"Or a person might have gone into Number Six from either Number Five or
Number Seven without your seeing him?"
