ISBN's: Trade Ed. 0-394-81241-7; GLB 0-394-91241-1 (post 1971)

Trade Edition First Printing Identifiers:
1.) No list on the back cover.
2.) Text error on page 47 (two lines flip-flopped half way down the page).
3.) A stitched textblock consisting of 6 signatures.
4.) Uncut blue graveyard endpapers (not slit down the center at the hinges).

Confusion Alert! - Books which have no list on the back cover but which have a glued textblock with "cut" blue graveyard endpapers should be considered a second printing.  The text error on page 47 of this later printing has been corrected.  These are commonly mistaken as First Printings.

"Windward White Cover"

First Printed: circa 1975/1976 
Cover Art: Ed Vebell

ISBN: Same as the Silverback above.

Notes: The Windward White Cover books (both "Terror Castle" and "Stuttering Parrot") are quite scarce. They are certainly the least common of the various U.S. Three Investigators editions/printings. There was most likely only one print run for each and they must have been very small ones at that. Click HERE for more information.

Notes: 
1.) There are two variations of this book to watch for and both are pictured to the left. The book at the top is the more common variation. The book on the bottom features a printed (not a sticker) promotional price of 99 cents on the front cover. This was available for a very short period of time.
2.) Confusion Alert! This title is a continuation of the Knopf "Bullseye Edition" paperback with new cover art and a new set of printings. Although there has been a change in the publisher, the ISBN's are the same and most of this book utilizes the printing plates from the Bullseye Edition.
3.) Confusion Alert! Random House also issued a hardbound library edition with the Dodge Covers. The ISBN found inside the hardbound edition is the same as that found in the paperback edition but the ISBN on the back cover is different: 0-613-08726-7.
