Breaks lock

He gestured up and Lois turned and began moving
as silently as she could up the stairs. Fortunately
Myron had chosen to live as near the roof as he could
afford, which left them only three flights from the top.

"It's locked," Lois hissed. "And what are we going

against the door and it clanked open. "It was just
stuck."

out into the night air. The roof was dark but dimly lit
by the light of the moon. The view of the city would
have been spectacular if Clark had been able to
appreciate it.

Clark closed the door behind them then stared at it
for a moment, welding it shut with his special vision
and keeping his body between Lois and the glowing
metal.
