The horns in the harbor booming, vaguely, 
Fog, forgotten, yesterday, conclusion, 
Nostalgic, noising dim sorrow, calling 
To sleep is it? I think so, and childhood, 
Not the door opened and the stair descended, 
The voice answered, the choice announced, the 
Trigger touched in the sharp declaration! 
 
And when it comes, escape is small; the door 
Creaks; the worms of fear spread veins; the furtive 
Fugitive, looking backward, sees his 
Ghost in the mirror, his shameful eyes, his mouth diseased.
Delmore Schwartz
