Closed! The news jolted Brother Francis. The shelter scarcely had been touched. Beyond his own adventure, there had been no attempt to penetrate further into the secrets of the shelter except to open the desk which he had tried to open, with no success, before he noticed the box. Closed! With no attempt to discover what might lie beyond the inner door marked "Hatch Two" nor to investigate "Sealed Environment" Without even removing the stones or the bones. Closed! The investigation abruptly choked off, without apparent cause.
