Trixie Belden and the Secret of the Mansion

Trixie Belden and the Secret of the Mansion by Julie Campbell (1948) This is the first Trixie Belden book, and she claims in the first paragraph that she'll die if she doesn't have a horse—I felt much the same way, as a lad, at least until I started drinking. Trixie makes what I think is going to be a lasting friendship with Honey Wheeler, the rich girl new neighbor. They're a great duo. The most annoying part of this book is Trixie's pest little brother, but I was glad he didn't die from the copperhead bite, which Trixie bravely administered first aid on. Thankfully, that slowed him down, at least. The mystery here, as you'd guess, is about an old mansion which holds a lot of mysteries and possibly some kind of treasure (a plot repeated over and over in kid's books). I like how the ending leads directly to the next book. I'm definitely planning on reading more.
