donât need to. I already know who took that Spork.â
âWho?â Biff asked.
âWho else?â Joe said. âIt has to be Adam Ackerman.â
Frank frowned. âWhy does it have to be him?â
âDonât you remember our first mystery?â Joe couldnât believe his brother didnât get it. âWhen all that money disappeared at the arcade, Adam turned out to be the thief. This is just like that time.â
âAdam is bad news,â Iola said. âHe steals peopleâs lunches at school all the time.â
Joe nodded. âLetâs go find him and tell him to give the Spork back before Mr. Roberts cancels the whole Morpho day!â
âHold on!â Frank said. âNone of us likes Adam. But we canât just accuse him of stealing the Spork with no proof.â
âWhy not?â Joe asked impatiently. âWe know he did it!â
âNo, we donât,â Frank said. âDad always says itâs important not to jump to conclusions, right?â
âYeah, I guess he says that sometimes,â Joe agreed reluctantly. âSo what?â
âSo, what if it wasnât Adam?â Frank said. âWe shouldnât get too focused on a suspect until weâre sure. Even if Adam is a pretty good suspect.â
âI think he might be right, Joe,â Phil said. âThat makes sense.â
âYeah,â Iola agreed. âThere are tons of people here, and we donât know all of them. Some of them might be just as rotten as Adam.â
Joe still thought Adam was the thief. But he realized his brother and the others were right.
âOkay,â he said. âEven if it is Adam, I guess we need some proof. Otherwise, heâll never confess.â
Frank smiled. âGood point. Iâm not saying itâs not Adam. Heâs definitely at the top of the suspect list. But we need some evidence or itâs just our word against his.â
âSo how do you find evidence?â Biff asked, looking interested.
âWe usually start out with the six W s,â Frank explained. âThat means we ask Who, What, When, Where, Why, and How and try to . . .â
Joe didnât hear the rest of what his brother said. Heâd just turned to scan the store.
âCheck it out!â he interrupted, pointing. âAdam Ackerman is trying to sneak out the front door right now!â
Looking for Suspects
W ait!â Frank yelled to Joe.
But it was too late. Joe was already rushing across the store toward Adam. Iola was right behind him, but Biff and Phil got left behind.
Frank hurried after his brother. He caught up just as he and Iola reached Adam.
âI knew it!â Joe exclaimed, pointing at Adam. âYou were the one who took that Spork, werenât you? Just admit it!â
Adam turned toward him with a scowl. â I knew it,â he said. âThatâs why I was leaving. You guys are always accusing me when bad stuff happens!â
Iola folded her arms across her chest. âThatâs only because youâre usually guilty,â she told him.
He glared at her, then at Frank and Joe. âI know you goody-goodies think Iâm always the bad guy,â he said. âBut I swear I didnât take that Spork. Iâd never do that to Morpho!â
âThen who took it?â Joe challenged him.
âHow should I know?â Adam shot back.
There was a big strong man standing by the front door. Frank noticed him looking their way with a frown.
âHey, you guys,â Frank said quietly. âLetâs back off, okay?â
âNot until Adam gives back the Spork,â Iola said.
Frank looked at Adam. Thatâs when he realized something. He grabbed Joe and pulled him aside, leaving Adam to argue with Iola.
âHold on a second,â Frank whispered. âIf Adam took the Spork, where is it? He isnât carrying a bag or anything.â
Joe looked at Adam. Then
