Miss Sweetstory was first mentioned on April 9, 1971. Snoopy reads her Bunny Wunny book, and, thinking it is the most exciting book he has ever read, decides to write a letter to the author. The next day, while Snoopy is writing his letter to her, he reveals that it is not a normal fan letter, but a love letter because he has fallen in love with Miss Sweetstory. When Snoopy gets a return letter from her, he is very excited to hold a letter which Miss Sweetstory has touched. It turns out that all the letter says is "Dear friend, Thank you for your letter. Sincerley, Helen Sweetstory". Lucy tries to convince Snoopy that it is a form letter, but Snoopy insists that she does not understand love. However, Snoopy's love for her comes to a halt when he finds out that she owns twenty-four cats.
