"Well, to begin with, the Nettleton Building faces in a southerly direction. From the head of the stairway the hall extends east to the light-well between the Nettleton and Field buildings. Beginning at the head of the stairs, the first room to the right, or on the south side of the hall, is the first office of the Guaranty Trust Company; the next suite is vacant, and then comes Doctor Westbrook's suite. I may add, that the numbers run in the order I am naming the suites: the Guaranty Trust Company's offices are number one, number two is unoccupied, and the Doctor's is number three.
"Now, passing over to the north side of the hall, the entrance to number four is directly opposite Doctor Westbrook's. It is the door to Mr. Nettleton's private office. Next to that, and facing the unoccupied suite, is Room 5, Mr. Nettleton's general office. Adjoining this is number six, a room occupied by the Guaranty Trust Company as a record and abstract room. That brings us back to the stairway again, but on the opposite side of the hall whence we started."
"Then there are six doors—three on each side—opening into the hall?"
"That is correct."
"Now, Mr. Lynden, are not the upper portions of those doors ground or frosted glass?"
At this apparently harmless and irrelevant question, the witness's composure dropped from him like a cloak cast aside; a swift, startled expression came into his light blue eyes, and he answered with obvious hesitation:
"I believe so."
"Don't you know?
"Yes."
"Well, are they?"
