Nancy Drew Diaries Collection Volume 7

The Ghost of Grey Fox Inn: 

It felt like only minutes had passed when I woke up with a start. I glanced over at the digital clock I had placed on the nightstand; it read 3:19 a.m. I had been fast asleep for hours — what had woken me up? I raised my head to look around the room, and my heart leaped into my throat.

There, standing at the foot of my bed, was a figure, looming in the darkness.

Riverboat Roulette:

I do have an idea. The most important thing, though," I said to Margot, Mrs. Marvin, and Catherine, "is for you to act completely normal. Our big advantage is that the thief doesn't think that anyone will check the safe until we're already back in River Heights and he or she is off the boat. The culprit has no idea that we're looking for him or her."

Margot, Mrs. Marvin, and Catherine all nodded.
I turned to Buddy. "What time are we due back at the dock?"
"Ten thirty on the dot," he said.
I checked my watch. "Just under three hours," I said.
I'd never solved a case that fast before, but the dogs and cats of River Heights were counting on me!
