recall seeing Marta? Helga?â
He shook his head, then said, âWait, Marta I remember. I saw her at the edge of the pool before Cheryl started to dive.â
âYouâre sure? Did you see which way she went?â
âThat I cannot say.â He frowned. âI think I wondered if she was leaving the pool, so she might have been toward the door. But I cannot be sure.â
He glanced at his watch and added, âI am sorry, I really must go to the track to warm up.â
âThanks, youâve been a great help,â Nancy said. âAnd good luck in the fifteen hundred meters.â
As Willy strode away, Cheryl turned to Nancy and said, âMartaâs the one, isnât she? That innocent look of hers is a lie!â
âWell . . .â Nancy hesitated. âIf Willyâs recollection is right, it means that she could have turned off the lights. It doesnât mean that she did. A lot of other people were here, too. And whether Marta had a part in any of the other incidents, we just donât know.â
âMaybe you donât,â Cheryl said grimly, âbut I do. And Iâm not going to take it lying down!â
She pulled her sweatshirt over her head and stormed off toward the locker room. Nancy hurried after her. Mr. Hornby was counting on her to head off trouble, and right now Cheryl was like a bundle of dynamite looking for a place to explode.
Cheryl pushed through the locker-room doors, with Nancy right behind her. Inside they found Annelise sitting on a bench in front of an openlocker whose door was beat up and dented. Annelise looked up, startled. She was in her shorts and jersey, and a folded pair of white warm-up pants was lying next to her on the bench.
âHave you seen Marta?â demanded Cheryl.
âShe and Helga were here a few minutes ago,â Annelise told her. âShe changed into running clothes and left. I think you will find her at the track.â She stood up and pulled on the white pants.
âHey!â Cheryl said. âHowâd you rate a fresh warm-up suit? You must know somebody!â
âIt is so stupid,â Annelise replied, looking embarrassed. âI spilled some juice on my pants. It is a guava juice I always drink when I am in training or competition, and it made a bright pink stain.â She gestured toward the open locker. âI tried to get it off, but it looked dreadful. So I told the man in the supply room, and he gave me these new pants.â
Cheryl nodded distractedly. âWell, Iâd better change and get over to the track. I need to have a talk with someone.â
She reached in the pocket of her sweatshirt for, the key to her locker. âWhatâ?â she murmured, pulling a piece of paper from her pocket.
âWhat is it?â Nancy asked.
Cheryl unfolded the paper, and the color drained from her face.
A second later, she handed the sheet to Nancy.
âGo home now,â the note read, âbefore itâs too late.â

Martaâs Confession
Nancy reread the threatening note, then asked, âThis wasnât in your pocket before, was it?â
Cheryl blinked. âNo, no. I would have found it when I dropped my locker key in, wouldnât I?â She fell silent for a moment, then burst out, âWhoâs doing this? Whoâs after me? Iâve never done anyone any harm. Why does somebody want to hurt me?â
âI donât know,â Nancy admitted. âBut Iâm going to do everything I can to find out.â
Holding the note by the corners, she studied it closely. The words in the message had apparently been cut from a glossy magazine. But what kind of magazine?
âWhat is it?â Cheryl asked.
âNothing,â said Nancy. âNot yet, at least. I wish I had a pair of tweezers with me.â
âTweezers?â Annelise asked. âOne moment.â She reached in her locker, withdrew a cosmetic bag, and
