An excerpt reads, 'I left my door ajar whilst I sat upon the edge of the bed finishing a cigarette and treeing my boots, preparatory to depositing them outside. Suddenly my attention was arrested by a somewhat curious sound. I distinctly heard the swift, stealthy footsteps of a man running at full speed along the corridor. I leaned forward to listen. Then, without a moment's warning, they paused outside my door. It was hastily pushed open and as hastily closed. A man, half clothed and panting, was standing facing me-a strange, pitiable object. The boots slipped from my fingers. I stared at him in blank bewilderment.'
