Square Paperback Editions

This is the last edition published Golden Books, a division of Western Publishing from 1984 to 1986.  This edition is best known for the last five books, numbers 35-39, which were first editions and are now difficult to find.

Oddly enough, not all of the series was released in this edition, despite the oval paperbacks being out-of-print when this edition was published.  The books list the entire series, at least up until 34, yet not all were published in this edition.  There were only 24 out of 39 books published in this format and there seems to be no explanation to why the other fifteen books weren't published.

1.    The Secret of the Mansion                            23.  The Mystery of the Queen's Necklace
2.    The Red Trailer Mystery                              26.  The Mystery of the Headless Horseman
3.    The Gatehouse Mystery                               29.  The Mystery of the Velvet Gown
4.    The Mysterious Visitor                                30.  The Mystery of the Midnight Marauder
5.    The Mystery Off Glen Road                        32.  The Mystery of the Whispering Witch
6.    The Mystery in Arizona                               33.  The Mystery of the Vanishing Victim
7.    The Mysterious Code                                   34.  The Mystery of the Missing Millionaire
8.    The Black Jacket Mystery                             35.  The Mystery of the Memorial Day Fire
9.    The Happy Valley Mystery                         36.  The Mystery of the Antique Doll
15.  The Mystery on the Mississippi                 37.  The Pet Show Mystery
20.  The Mystery Off Old Telegraph Road      38.  The Indian Burial Ground Mystery
21.  The Mystery of the Castaway Children     39.  The Mystery of the Galloping Ghost

There was a number 40 scheduled to be written by Kathleen Krull (author of #28) and set in San Diego but the series was cancelled before this was either written or published.  However, there is an unofficial #40 written by Melanie Kay Knight called "The Mystery at Mansion House" and is only available in an electronic format.

The information provided here covers the books from my own collection and is not representative of all the books produced at this time.  There were a number of reprints of these books so the title listing may vary depending on which print run the book is from.
