This is the original 1928 story of The Missing Chums: The Hardy Boys Book 4. The book has undergone one major revision since its original publication in 1928, resulting in two significantly different stories bearing the same title.

Chet and Biff, chums of Frank and Joe Hardy, intend to take a pleasure trip down the coast in Biff's new boat. They start during an ominous storm and then disappear. Mr. Hardy leaves to capture a dangerous criminal he has been tracking. Frank and Joe set out to find Chet and Biff over the great objections of their visiting Aunt Gertrude. When Frank and Joe finally find them, they are all captured. The Hardy Boys use their investigation skills and lots of courage in dangerous situations to find and rescue Chet and Biff—the missing chums.

Much has changed in America since 1928. The modern reader may be delighted with the warmth and innocence of the characters, but uncomfortable with the racial, social, and sexist terms and stereotypes. As such, this book is a part of our heritage, a window into our real past.
