"There is an outer office for the clerks; opening from that, a smaller room where my desk is placed. Opening from my room was Mr. Holladay's private office.
"Had Mr. Holladay's office any other door?"
"No, sir."
"Could entrance be had by the windows?"
"The windows open on the street side of the building. We occupy a part of the eighth floor."
"The fire-escapes——"
"Are at the back of the building—there are none on the street side—nothing but a sheer wall."
"So that anyone entering or leaving the private office must necessarily pass by your desk?"
"Necessarily; yes, sir."
"Could anyone pass without your seeing him?"
