This volume collects the first 8 novels in the original Hardy Boy series, before it was rewritten and dumbed down in the 1950s for a sanitized TV-raised audience. These adventures, first published in the late 1920s, feature rougher, tougher versions of Frank and Joe Hardy, willing to take chances -- and pay the price -- to solve mysteries. So if you think you know these books based on later versions, you're going to be in for a very pleasant surprise: they're better. Included are: The Tower Treasure The House on the Cliff The Secret of the Old Mill The Missing Chums Hunting for Hidden Gold The Shore Road Mystery The Secret of the Caves The Mystery of Cabin Island
