book

My husband and I are actively checking thru any old books we find for a copy of "Castle In The Swamp". I remember reading it in the early 60's and someplace and sometime over the last umpteen years and many moves i lost my copy. If anyone runs across a copy of it while antiquing or thirft storing, pls. let me know where and how much. If it is not over a couple of $'s, if you would buy it and d-mail me I would be glad to reimburse you for your expense. Thanks. Liz
