"Nancy's Alaskan adventure continues as she, Bess, and George disembark the mystery-plagued Arctic Star cruise ship and explore the grand sites of the forty-ninth state: Skagway; the Yukon territory, and Denali National Park. It's spectacular scenery, but things start to go wrong almost immediately, leading Nancy to believe that whoever was behind the unsolved mayhem aboard the ship has followed them onto dry land. The girl detectives had better watch...

"Hey," I said as my friends and I stepped in. "Have either of you guys seen Dana lately? Or Payton?" The girls spun around. "Nancy!" Rachel exclaimed. "Oh my gosh, I can't believe it!" "Can't believe what?" I asked. "Come look!" She grabbed my sleeve, dragging me to the saddle rack. "Can you believe someone did this to Payton's saddle?" I gasped! The saddle's seat had been slashed to ribbons!

When I saw what was inside, my stomach roiled and I had to look away. Who would send something...

People at Black Creek are getting very sick from fresh fruits and vegetables crawling with deadly bacteria and Nancy is going to find out who is responsible for sabotaging the Heyworth's farm.
