Now and again Lena stopped and glanced behind her. Every time she did so
the boys stopped too; evidently she was afraid of being followed. They
met few people and those who did pass them apparently took them for a
couple of tramps, for they paid no particular attention to them.

A little distance down the street Lena turned the corner to her right.
The two boys as a consequence had to run in order not to lose sight of
her. They were fearful lest she should slip away from them and therefore
were greatly relieved when they came to the turn and saw her still in
front of them.

A few moments later she turned again, and then presently, turned still a
third time.

"She's trying to lose us," whispered Bob.

"Maybe not," said Hugh. "This is Elm Street."

"Where's twelve eighty-two!"

"On the next block."

The white stucco house was on the same side of the street with the boys,
and as Lena came opposite it she crossed over. Bob and Hugh stopped short
under a large maple tree whose trunk cast a shadow affording ample
protection from a nearby arclight. From this vantage point they watched
the woman they were trailing.

"She's going in," whispered Bob, clutching Hugh's arm excitedly.
