When a friend of Nancy’s father is arrested for sending a truck of oranges rigged to explode, and Nancy offers to help out in any way possible. During her investigation, Nancy becomes suspicious of a mansion that has strange noises coming from the yard, and tries to add that to her list of mysteries to solve.
This was an interesting one and I felt like it had some foreshadowing of what the books could hold in the future as Nancy finds a house she feels her father should buy for them.
Another situation arises in which Nancy finds herself facing death, with company this time as Ned is locked up with her in a secret room full of boiling water.
This was a good thriller and very enjoyable read.
