We stopped talking to think and to take two calls that came in.

Then, in a very small voice, and even though I had just been thinking the opposite an hour earlier, I said, "Maybe I should tell my dad about - " "No!" exclaimed Logan. "We're not involving any adults. No parents, no police." "Why not?" I asked.

"Because they'll just get in the way. A kid wrote that note. Don't you think so? Look at that big, babyish handwriting. And an adult would want more than a hundred dollars. Why would a grown-up go to all the trouble of stealing a kitten for three days, just to get a hundred dollars? It's not worth it." "That's true," the rest of us agreed.

"So?" said Kristy.

"Well," Logan went on slowly, "we don't know if that note is from an actual kidnapper, or just from someone trying to take advantage of Tigger's situation, but either way we should catch him - " "Or her," added Dawn.

" - or her. Don't you think?" I looked at my friends. We all nodded. This was getting sort of exciting.

"How are we going to catch the kidnapper?" wondered Jessi.

Logan frowned thoughtfully. He read the ransom note again. " 'In an envelope on the big rock in Brenner Field at four o'clock/ " he mused. "Do you know what the big rock is?" he asked the rest of us. "I don't even know where Brenner Field is." "It's right nearby," Claudia told him. "That's probably why you don't know it. It's not in our neighborhood. If s sort of behind Jamie Newton's backyard." "And do you know this big rock?" asked Logan.

"Oh, sure," I replied. "Everyone does. There's a boulder near one side of the field. We just call it the Trig rock.' " Logan nodded. "Listen, you guys," he said to the six of us girls, "I'm getting an idea, but I'm going to need the help of all of you - or most of you - tomorrow." "We'll be there," said Kristy, without even looking at the record book.
