JOE. [_Turning to the purse again._] First time in my life I've been afraid
when I heard the policeman.
[_He has his finger on the catch of the purse when he pauses for
a moment--then acting on a sudden impulse, makes a dart for the
door, opens it, and is out, and up the area steps._
MARY. [_With a despairing cry._] Joe!
[_She flings herself on the mattress, and sobs silently, so as
not to awaken, the child._ JOE _returns, hanging his head,
dragging one foot before the other._
MARY. [_Still sobbing, but trying to control herself._] Why did you do
that?
