| FOREWORD |
| FRANK and Joe Hardy suspect that their best friend Chet Morton is the victim of a summer school swindle and offer to help get his money back. While probing a baffling burglary at the Seneca Indian Reservation in New York State they investigate Zoar College located nearby. Clues that Frank and Joe uncover indicate that there is a connection between the Zoar College swindle and the theft of the Senecas' gold tribal relic Spoon Mouth. This startling discovery propels the teen-age sleuths into a series of perplexing and dangerous situations. Two strange-acting college professors, a valuable coin collection, and a taciturn Indian who refuses to discuss the mystery surrounding Spoon Mouth - all blend into a fast-paced story with several surprise twists that will thrill the vast legion of Hardy boys' fans. |
| FRANK and Joe Hardy become involved in an intrigu- ing mystery which revolves around their fencing master, Ettore Russo. Proof that Russo is the rightful heir to his grandfather's estate hinges on retrieving the guard end of a broken saber lost many years ago in California. The young investigators' quest is complicated by a bank robbery during which some of their father's im- portant records are stolen. Using Mr. Hardy's recently purchased scientific device, a sound spectrograph, the boys identify the voiceprints of the leader of the masked robbers. A chase ensues that takes Frank, Joe, and their pal Chet Morton to the grape-growing region of Cali- fornia and involves them in a dangerous game of hide- and-seek with the bank robbery gang, who also are searching for the broken saber. A startling discovery at a movie location leads to the solution of this thrilling, fast-paced mystery. |
| TWO unexplainable plane crashes near an airport on the East Coast plunge Frank and Joe Hardy into a bizarre case. When their famous detective father is called to New York City by a group of insurance companies to investi- gate air freight thefts at Kennedy International Airport, Mr. Hardy asks Frank and Joe to take over his current case of the suspicious plane accidents. From the moment Frank and Joe find a radioactive engine in an airplane junkyard, unexpected dangers strike like lightning. Despite the repeated attempts on their lives, the teen-age detectives pursue their investi- gation and make a second startling discovery involving contraband uranium isotopes. These two vital clues and others that Frank and Joe unearth provide the solution to one of the most baffling mysteries the boys and Mr. Hardy have ever encountered. |
| WHEN thieves hijack a collection of stuffed animals from a country auction, Frank and Joe Hardy pursue the getaway car and are drawn into a thrilling mystery. The recently acquired interest of their best pal, chubby Chet Morton, in taxidermy as a hobby adds fresh twists to the puzzle. At the same time, the young detectives' father - famed private investigator Fenton Hardy - is tracking down an industrial spy ring. Over the Hardys' ham radio, Frank and Joe pick up a coded message from the spies, consisting of names of various wild animals. Are the industrial spies somehow mixed up in the hijacking at the auction and the rash of stuffed animal thefts that follow? This suspense-filled story of pursuit and detection will keep the reader breathlessly following the chain of un- expected developments that lead Frank and Joe to the spine-tingling climax in the wilds of Northern Canada. |
| Another exciting mystery begins for Frank and Joe Hardy when they help a stranger who has had an ac- cident with his car. The man introduces himself as John Mead, owner of a nearby estate. After he con- tinues on his way, Frank finds an odd-looking house key which belongs to Mead. But when the Hardys try to return it, they learn that John Mead died five years ago! They are even more amazed when they find that the intricately carved doors in the dead man's deserted mansion have no visible knobs or keylocks. While working on this mystery, the boys assist their detective father in tracking down a highly organized ring of thieves who are robbing warehouses of tele- vision and stereo equipment. What happens when Frank and Joe discover that there is a link between Mr. Hardy's case and the mysterious Mead mansion will keep the reader on edge with thrills and suspense. |
