The Hardy Boys Original Series

In 1926, the founder of the Stratemeyer Syndicate, Edward Stratemeyer, conceived the idea for the Hardy Boys. He created the plot outlines and then advertised for ghostwriters to complete the stories. Most notable among these writers is Leslie McFarlane, who wrote volumes 1-16 and 22-24 and is generally regarded as by far the best ghostwriter of the series. The first three volumes of the series were released as a "breeder" set in mid-May 1927. There were five more stories published in the following two years. After that, new titles were released in an almost unvarying pattern of one per year for the next fifty years.

Starting in 1959, the Stratemeyer Syndicate engaged in a 15 year project to revise the first 38 titles in the series. The earlier books were printed from copper plates which over the years had degraded so that copies printed from them were of poor quality. The revisions ranged from slight alteration to completely new stories. All the stories were reduced in length (all stories were now the same approximate length), had obsolete prose updated and had racial stereotypes (which appeared in many of the early volumes) removed. The quality of the revised stories is generally so far below that of the originals that it can only be considered as an act of literary vandalism.

In 1979, after 52 years and 59 titles (which includes Detective Handbook), Grosset & Dunlap lost the rights to publish any new Hardy Boys tales in a protracted court battle with the Syndicate. They did retain the right to continue publishing these 59 titles (refered to by most Hardy Boys enthusiasts as the canon) and continue to do so to this day, despite several changes in ownership (today it is part of Penguin Random House through its subsidiary Penguin Group.)

In 1991 Applewood Books began to publish first edition facsimiles of the early volumes. Dust jackets on earlier volumes are marred by an ugly "Just As You Remember Them" logo on the front cover. Thankfully, this was moved to the spine on later volumes. Beginning with volume 12, Footprints Under the Window, Applewood abandoned its practice of making facsimiles when it continued to use red cloth binding despite the fact that this title never came in that format. In 2007 Applewood announced it was not renewing its agreement with Simon & Schuster and would not continue publishing Hardy Boys books.

In 1962, Grosset & Dunlap changed the format of the books from dust jackets to picture covers (PC). Four original text stories (volumes 1, 2, 11 & 14) are not known to exist in picture cover format. Three revised text books (volumes 1, 2 & 14) were issued with dust jackets.

Early editions (1927-1932) with dust jackets are very scarce and are highly prized and sought after by collectors and a true first edition of The Tower Treasure is the Hardy collector's Holy Grail. Additionally, the first edition of volume 11, While The Clock Ticked, is extremely rare and perhaps the most valuable of all Hardy Boys books.

First editions of any volume, first editions of new cover art, first editions in PC format and first editions of revised texts are also very desirable and tend to bring higher prices. First editions of books with modified (not revised) text are sought by Hardy completists.

Authors are known from signed releases found in the Stratemeyer Syndicate Archives at the NY Public Library. The archives are occasionally contradictory and other documents indicate different authors for some titles. In some cases this conflict may be due to manuscripts being rejected by the Syndicate. These will be noted where applicable but the signed release forms are usually the best indicator of true authorship.

From 2005 until circa 2013 Grosset & Dunlap reprinted volumes 59 thru 66 of the Digests using the original art in the Flashlight picture cover binding style.

Starting in 2023 the early original text versions began entering the public domain and started showing up on Project Gutenberg and in paperback editions of varying quality.

The Hardy Boys break up a counterfeiting ring centered at an old mill on the outskirts of Bayport.
Counterfeit money is in circulation, and the limit is reached when Mrs. Hardy takes some from a stranger. Then the Hardy boys and their high school chums are warned to stay away from the old mill. Their curiosity plunges them into peril of the most unexpected kind.
Description of current edition: "Drop case or else danger for you and your family." This warning addressed to Fenton Hardy not only alarms the famous investigator and his detective sons, but also puzzles them, because Mr. Hardy is working on more than one case. Which one prompted the threat?
When more ominous warnings follow, Frank and Joe suspect there is a link between the counterfeiting case they are investigating and a secret case their father cannot discuss since it involves national security.
The key to the solution of both cases appears to be hidden in the old Turner mill, constructed in frontier days but now a gatehouse for Elekton Controls Limited engaged in manufacturing top-secret electronic parts for space missiles. But the millhouse is occupied by two Elekton employees who are hostile to Frank and Joe and refuse to allow the young detectives to question the company's fourteen-year-old messenger boy who unknowingly may be in possession of some vital clues.
Determined to learn the secret of the old mill, Frank and Joe employ a clever ruse to gain entrance, only to find themselves trapped in a subterranean passageway. How the young detectives extricate themselves from this dangerous situation and unravel both mysteries will keep the reader tense with suspense.

Description of current edition: Something is amiss in Bayport, the Hardy boys' home town. First, there is trouble in Shantytown, then a strange black craft tries to ram Joe and Frank's boat, the Sleuth. That night the local bank is robbed. And later that same night the young detectives' pals, Chet Morton and Biff Hooper, mysteriously disappear after a masquerade party. Are the events related? And do they emanate from Shantytown-or from Hermit Island, an isolated land mass inhabited for many years by a strange recluse? Is it significant that both the missing boys and the bank robbers wore masquerade masks? Or is it more important that Chet was wearing a costume identical to Frank's? One by one, Frank and Joe tackle the clues, hardly daring to think what might have happened to their missing friends. But it is not until the two brothers confront the kidnapers that the overall pattern begins to emerge. The kidnapers ruthlessly plan to force Frank and Joe's famous detective father into choosing between justice and his sons! How the Hardy boys use all their courage and skill to outwit the criminals provides an exciting climax to one of the most baffling mysteries the young detectives have ever encountered.

Art: 1987 Rudy Nappi (Modification of 1972 art)
Notes: Considered as part of the original series by most collectors.
Now out of print.
Originally an oversized book, this volume was reduced in size to match the rest of the series in 1987.
Both the putative "authors" were law enforcement officers.

On Jan. 14, 1957 the Syndicate sent Spina a $300. check for his outline of the Handbook. They said that the publisher liked the idea and wanted to see a sample chapter.
More than a year later, a letter of agreement from the Syndicate on Jan. 21, 1958 indicated that Spina would be paid $150 for each of the 10 chapters planned in addition to the $300 for the outline already paid. The chapters would be turned in as batches of 3, 3, and 4 with payments of $450, $450, and $600. All chapters were to be turned in by July 1, 1958 and he would help with revision as needed.
On Sept. 12, 1958 the Syndicate sent a manuscript of the first four chapters to Spina for review on details of police procedure.
Svenson sent a release and check for $1,050 to Spina on Sept. 26, 1958. He said that he still had four chapters to edit which would be sent to Spina soon. He says that after the text was put into type he wanted to send galley proofs for Spina to review.
A draft of the foreword was sent to Spina by Svenson on Oct. 20, 1958.
On Dec. 17, 1958 Svenson sent $200 more for his editing of the galley proof of the Handbook.
It appears that Spina was paid $2,000 in 1957-58 for his work outlining ($300), writing ($1,500) and editing ($200) the Handbook. He was also a correspondent with the Syndicate on occasion, including supplying some notes on the structure of police departments in Germany for a story.
