The House On The Cliff is the second book in the original The Hardy Boys Mystery Stories published by Grosset & Dunlap. The book ranks 72nd on the "Publishers Weekly's" All-Time Bestselling Children's Book List in the United States with 1,712,433 copies sold . This book is one of the "Original 10" "Hardy Boys" books and is an excellent example of the writing style used by the Stratemeyer Syndicate's writers. This style influenced many other "youth adventure series" books that the Stratemeyer Syndicate also published, including the Nancy Drew series (designed as a corollary to "The Hardy Boys" written from the perspective of young girls), the Tom Swift adventure series, the Bobbsey Twins and other lesser known series. All of them used a unique writing style that made them very recognizable as Stratemeyer product.
