Balcom tried to comfort her. But somehow his sympathy sent a cold shudder through the poor girl.

Meanwhile Zita had encountered Locke hurrying down at the sound of the commotion. To him she told the story, again hurt that his interest was solely for Eva, not in herself.

Locke paused long enough to seize an umbrella from the rack, rip the cover off, and break out a rib, to which he tied a piece of string while he hurried to the group at the door.

"Break down the door and call the police," ordered Balcom.

The butler reached for a chair and was about to swing it over his head to break down the door.

"Stop!" interrupted Locke.

The young scientist knelt down, inserted the umbrella steel through the keyhole, and bent it by the string as he fished about with it on the other side to find the bolt. Meanwhile the butler telephoned frantically for the police.

It was at this height of excitement that Paul Balcom entered. A moment's talk with Zita, and he, too, joined the group.

Sympathetically he spoke to Eva, but Eva scarcely responded in the fashion of a girl to the man whom she was going to marry. Her attention was riveted on Locke, who was kneeling before the door. Paul saw it and an ominous scowl crossed his face.

Carefully Locke worked the umbrella steel and the string until he had caught the bolt. Then he shot the bolt back and rose to his feet. All watched him expectantly as he threw open the door.
