Chirk is secretary to Terl, at the mining installation near Denver, Colorado.
Terl considers Chirk stupid enough not to be any menace and good-looking enough to be decorative. She can get drunk with economical speed and has other advantages too.
Her main job is in blocking off callers and shuffling administration papers back for somebody else to handle. In spite of being a rattlebrain, Chirk leaks vital information to Jonnie that helps the rebellion.
