The House on the Cliff by Franklin W. Dixon, available in Auren as a public-domain ebook in the United States.
I
Three powerful motorcycles sped along the shore road that leads from the city of Bayport, skirting Barmet Bay, on the Atlantic coast. It was a bright Saturday morning in June, and although the city sweltered in the heat, cool breezes blew in from the bay.
Two of the motorcycles carried an extra passenger. All the cyclists were boys of about fifteen and sixteen years of age and all five were students at the Bayport high school. They were enjoying their Saturday holiday by this outing, glad of the chance to get away from the torrid warmth of the city for a few hours.
When the foremost motorcycle reached a place where the shore road formed a junction with another highway leading to the north, the rider brought his machine to a stop and waited for the others to draw alongside. He was a tall, dark youth of sixteen, with a clever, good-natured face. His name was Frank Hardy.
