They went down on their haunches and crept along in single file, out into the dismal swamp, and drew near the oasis.

The detectives keenly watched it, hoping they might catch view of some human beings about the place.
At the end of quarter of an hour, they were suddenly startled by hearing a wild, piercing cry in human tones, of:
"Help! Police! Murder!"
The Bradys were intensely startled.
