midnight
He breathed a great sigh of relief when he reached the open air . He turned down a side street to collect his thoughts before deciding what to do . He wandered till he reached the middle of the block , then , finding his valise heavy , he set it down on the sidewalk to rest a minute . It was after midnight and very quiet . Suddenly he felt something hit him in the face , and then for a minute or two all was a blank to him . When Rex came to his senses again he found himself leaning against a brown stone stoop . His head felt very queer .
