“The probability, you mean,” corrected Louise.
Penny retied her shoes and glanced toward the hotel. Far up the beach she saw Mrs. Deline, and the widow was walking slowly toward the sand dunes.
“Duck!” Penny ordered, rolling over one of the high ridges. “We don’t want her to see us here. She’ll suspect what we’ve been up to.”
Louise crouched behind the dune with her chum, though she complained that she felt silly doing it. Apparently, Mrs. Deline had not seen the girls. She came steadily on.
Drawing close, she peered directly at the dune where the girls had taken refuge. For a second they feared that she had seen them. But she passed on without another glance.
“It looks to me as though she’s on her way to the lighthouse again,” Penny remarked after Mrs. Deline was far down the beach. “Wonder why she goes there so often?”
“I thought visitors weren’t allowed.”
“According to the rules they’re not.”
From behind the dune, the girls kept watch of the widow. Presently they saw her climb the steps of the lighthouse and disappear into the interior.
“Well, that settles it!” Penny exclaimed indignantly.
