Without another word, she took all the

candy and junk food off the tray and then turned to the cashier. "Please just ring up the burgers and fries."

"Kristy!" Jackie howled. She ignored him, paid the cashier, and picked up the tray. Archie gulped down the last of his candy bar — probably afraid he would have to give it back — and hurried after her.

It was much later in the afternoon when Kristy breathed a small sigh of relief. The day was almost over, and nothing else had gone wrong. Or had it? Suddenly she realized that someone was missing. Her heart hammered in her chest. There was Archie, kicking in the wading pool. . . and there was Shea, showing off in the diving pool, and Jackie . . . wait a minute . . . Jackie was missing!

Frantically, Kristy scrambled to her feet and ran a few steps to the diving pool. The crowd had thinned out since lunchtime, and it was obvious that Jackie wasn't there. She dashed to the edge of the Olympic-sized-pool.

"Jackie!" she called. A few kids stopped swimming to look at her, but she knew she was wasting her time. Don't panic, don't panic, she thought. She forced herself to slow down and take a deep breath. Racing around the pool complex was crazy. The right thing

for a baby-sitter to do in a situation like this is to notify a lifeguard. Immediately.

"Don't worry, he's around somewhere/' said the nearest lifeguard encouragingly. "We'll page him over the loudspeaker."

"Thanks." Kristy leaned against the lifeguard station, noticing for the first time that her legs were shaky. Will Jackie Rodowsky please report to the lifeguard station? The voice boomed over the address system every few seconds, with no results. Five minutes passed, then ten. Kristy felt like her heart was playing leapfrog in her chest. Where was Jackie? What would she tell Mrs. Rodowsky?

In the end, it was Shea who found him. "Here he is!" Shea said triumphantly. He was leading a puzzled-looking Jackie to the lifeguard station. "Boy, are you gonna get it!" he said happily to his brother.
