Once Nancy, Bess, and George arrive in Pennsylvania, they encounter Manda Kreutz, who has run away from home. Manda disappears, and Nancy is asked to help find her.
Of course, Ned, Burt, and Dave are able to travel to Pennsylvania Dutch country to help the girls with the mystery.
I did not notice much wrong with this story. However, pages 47-49 of the revised text (pages 67-69 of the original text) gave me pause. On page 47:
When Nancy's car was refueled, they set out again. As she rounded a sharp turn, she suddenly gasped and stepped on the brake. Strewn across the road, directly in their path, were cinder blocks. There was no way to avoid plowing into them!Hitting a bunch of cinder blocks would result in damage to the automobile. Since the girls were thrown forward, the impact was significant. Yet the girls were able to quickly drive away after clearing the blocks with no mention of any damage to the vehicle. At the very least, a statement should have been made about the vehicle, even if only to mention minor damage.
The car hit several of the blocks. All three girls were thrown forward. Bess, seated in the middle, struck her head on the mirror and blacked out!
This is a good story. While I don't usually like the travel books a great deal, this one is okay. Nancy has traveled to a location distant to River Heights, but the entire mystery is centralized in that new location, so the feel is similar to mysteries set around River Heights. The German phrases and bits of trivia about the Amish that are scattered throughout the text are not annoying.
This book has many events that appear to be coincidence, but they are more a result of cause and effect, so the story is plausible. Both texts are good, and I see no significant difference between them.
