In their second thrilling adventure, set against the eerie backdrop of Bayport's windswept coastline, teenage sleuths Frank and Joe Hardy find themselves entangled in a dangerous mystery when they investigate a crumbling, cliffside mansion. With the help of their father, renowned detective Fenton Hardy, they uncover a sinister smuggling operation that threatens their community. As they navigate hidden tunnels, secret codes, and treacherous villains, Frank and Joe must rely on their wits and bravery to expose the truth and bring the criminals to justice. This is a reprint of the 1927 first edition of The Hardy Boys: The House on the Cliff, without cuts or censorship, as originally written by Leslie McFarlane under the pen name Franklin W. Dixon.
