To their friends' envy, Biff and Chet plan to take a boating vacation up the coast. The joy of sending them off soon turns to anxiety as neither of them make contact with home for several days. Convinced that something's happened to them, the Hardy boys and their friends go on a search filled with adventure and peril in hopes of retrieving their missing chums.

This is the fourth book of the Hardy boys series, first published in 1928. While the author is credited to be Franklin W. Dixon, in reality, Leslie MacFarlane and Edward Stratemeyer are primarily responsible for the early volumes, including this one. This Standard Ebooks edition is based on the original 1928 text.

Perfect for readers who love classic mystery adventures and timeless detective stories that have captivated generations of young sleuths! This thrilling tale of friendship, danger, and determination showcases the Hardy Boys at their finest as they race against time to solve their most personal case yet. A must-read for anyone who enjoys fast-paced mysteries where loyalty and courage triumph over peril.
