person could've unbolted the door for him earlier, without his doing the ten-foot dash down the rear hall to unbolt the door himself at half past nine. So I don't see that your interesting little drama helps Jessup out any."
"Oh, but the drama isn't over," Vance replied. "The curtain is about to go up on the next act."
Heath lifted his eyes sharply.
"Yeah?" His tone was one of almost jeering incredulity, but his expression was searching and dubious. "And you're going to show us how Skeel got out and bolted the door on the inside without Jessup's help?"
"That is precisely what I intend to do, my Sergeant."
Heath opened his mouth to speak, but thought better of it. Instead, he merely shrugged his shoulders and gave Markham a sly look.
"Let us repair to the public atrium," proceeded Vance; and he led us into the little reception-room diagonally opposite to the switchboard. This room, as I have explained, was just beyond the staircase, and along its rear wall ran the little passageway to the side door. (A glance at the accompanying diagram will clarify the arrangement.)
Vance shepherded us ceremoniously to chairs, and cocked his eye at the Sergeant.
"You will be so good as to rest here until you hear me knock at the side door. Then come and open it for me." He went toward the archway. "Once more I personate the departed Mr. Skeel; so picture me again en grande tenue—sartorially radiant. . . . The curtain ascends."
