Hardy Boys The House on the Cliff

Fenton Hardy, the famous private detective and father of the Hardy Boys, asks his sons to help him with his latest case involving a criminal named Snattman and the illegal drug trade smuggling of stolen drugs. Hardy directs Frank and Joe to a house on the cliff, whose location overlooking Barmet Bay offers an excellent vantage point to watch for smugglers. The Hardys are tricked into the house by cries for help, and are trapped for a short time in the attic; meanwhile, their telescope and motorcycles are damaged, possibly by the smugglers. On the way home, they observe a man boating on Barmet Bay being chased by another motorboat. After his boat explodes in flames, Biff and Joe swim out while Frank and Chet get a rowboat to rescue the man. Once brought to shore, the man regains consciousness and says his name is Mr. Jones, which the Hardys believe to be a thinly-disguised alias. The next day, both Mr. Hardy and Mr. Jones disappear. Frank and Joe seek out Mr. Hardy's informant at the maritime docks, Pretzel Pete, to see if he knows anything about the smugglers. Frank and Joe revisit the Shore Road area, and inside the house not far from the house on the cliff, Frank sees Mr. Hardy's hat. With their friends Chet Morton, Biff Hooper and Tony Prito, they use a boat to search for a secret tunnel at the base of the cliff. Frank and Joe try to rescue Mr. Hardy but they are also captured at gunpoint. Chet and Tony go to the United States Coast Guard and find Biff Hooper, Jerry Gilroy, and Phil Cohen there and lead them to the smuggler's secret cave. It turns out that Mr. Jones was a spy working for the Coast Guard. At the end the Hardys escape into the house on the cliff, and capture Snattman while he is negotiating with police. Snattman apologizes and says he will turn the house on the cliff into a Boys Home - a place where boys without proper home training can come to live.

Hardy Boys Tower Treasure

The story begins with Frank and Joe Hardy barely avoiding being hit by a speeding driver with bright red hair. Later, this same red-haired driver attempts a ferryboat ticket office robbery and successfully steals a yellow jalopy called Queen from the Hardys' friend, Chet Morton. Due to one witness reporting that the villain had dark hair, the Hardys assume he is using a red wig. It is learned that the thief returned to Chet's home to steal a tire, helping Frank and Joe to find Queen abandoned in a public wooded area.
The excitement of finding Queen is quickly gone when it is reported that there has been a robbery of forty thousand dollars in securities and jewels from the Tower Mansion owned by siblings Hurd and Adelia Applegate. Hurd Applegate is convinced that the Tower's caretaker, Henry Robinson, is the guilty party. The Hardys are especially concerned by this accusation because Henry's son, Perry, is a friend of theirs who will have to quit school to work since his father can no longer get a job as a result of Applegate's accusation. The only 'proof' of Henry Robinson's guilt is that he was suddenly able to pay off a debt, and refused to reveal where he got the money to pay off the debt.
The Hardys suspect that the red-haired man may be involved with the Tower robbery and search the place where Queen was found, finding the red wig. The Hardys' dad, detective Fenton Hardy, learns that the wig was manufactured in New York City. The three Hardys go to New York and learn of a criminal named John "Red" Jackley who is fond of using disguises. Soon, Jackley is injured in a train accident causing him to be hospitalized. About to die, Jackley confesses that he committed the Tower Mansion robbery and put the loot "in the old tower…" Jackley dies before he is able to explain further. After searches inside and outside of the Tower Mansion the stolen loot is still not found.
Frank and Joe decide to go to the railroad where Jackley used to work to find out more information. While investigating, they see two water towers nearby. The Hardys realize that Jackley was referring to the old water tower and not the Tower Mansion. Inside the water tower they find the stolen items but are locked in the tower by a man calling himself Hobo Johnny. Johnny feels anything in the tower belongs to him. Frank and Joe break out of the water tower and return the securities and jewelry. In the original version of the book Henry admits that a man who owed him money repaid a debt to him, but he was not allowed to tell anyone in case the man's other debtors found out. This was revised in the 1959 version such that Adelia reveals that she loaned Henry Robinson the money to pay off his debt. Following the revelations and with the stolen loot returned, Hurd re-hires Henry with an increase in salary and Hurd builds a greenhouse for Henry.
