leveled the pistol and took careful aim at the man.
Now! Nancy thought.
Her head whipped back, striking Boomer flush on the chin. He yowled. Feeling his grip loosen, Nancy slipped out from under and gave him a solid judo chop to the ribs. Boomer stumbled. Nancy jumped him, grabbing his wrist with both hands, and hammered his gun hand against the fender. The pistol clattered to the floor. Nancyâs foot swept it under a nearby car.
She heard running feetâthe anxious shouts of Ned and Bess.
Boomer bolted. âMore cops!â
After he ran up to Nancy, Ned hugged her. âYou all right?â
âIâm fine.â She pointed at Boomer, who was heading for the stairwell. âAfter him, Ned! We canât let him get away.â
Ned and Nancy took off in pursuit. Bess brought up the rear. They charged up the stairway in single file, Ned in the lead. Nancy took the steps two at a time. She was thinking, What was that moon-faced guy doing here? Was he following me? But how does he know who I am? He couldnât have seen me in Lisaâs window!
Clang! Boomer pushed a steel trash can over the edge of the stairs. It tumbled toward them!
Ned tried to dodge, but his foot slipped on the step. The can rolled right over him, and he went down hard.
âNed!â Grabbing Bess, Nancy pushed her against the railing. The can bounced past them, spilling trash all over the stairs.
âIâm okay, Nancy. Go get him!â Ned said.
Nancy raced to the balcony. She spotted Boomerâs blue- and orange-flowered shirt just ahead, disappearing into the mall crowd.
Shoving people aside, Boomer bulled his way down the main corridor. Angry shouts exploded all around him. Nancy stayed on his heels, zigzagging between startled shoppers.
At last the crowd thinned out and disappeared. They were in a little turnoff now, a hallway lined with supply closets. Once in the clear, Nancy put on a sudden burst of speed. She came right up behind Boomer and brought him down with a tackle worthy of a pro football player.
Nancy and Boomer rolled over and over across the polished floor. Breaking free, Nancy jumped to her feet. Boomer got up groggily, saw who it was, andâsnarling with rageâthrew himself at Nancy.
Nancyâs right leg scissored in a flawless judo kick. Her sneaker clobbered Boomerâs chinâhe went over like an old dead tree.
Boomer lifted his hands in surrender. âOkay, okayâthatâs enough. Iâm busted, man. I want to see my lawyer.â
Nancy knelt beside him. âBoomer, Iâm not a cop.â
âWeâre just concerned citizens,â Ned added, coming up behind them and pinning him to the floor.
âThen how about letting me go?â Boomer tried to sit up.
âAfter you put a gun to Nancyâs head? No way, pal!â
âBoomer, weâve got you cold on assault and unlawful possession of a gun.â Reaching across the floor, Nancy retrieved her shoulder bag. âTell you what, though. If youâll answer a few questions for me, I wonât mention that you took aim at that black-haired guy.â
âAll right.â Boomer sighed. âAsk your questions.â
Nancy took the photo of Lisa Trumbull out of her bag. âHave you ever seen this girl before?â
âYeah, Iâve seen her.â He tilted the photo slightly. âShe came up to me on Waikiki Beach yesterday. Two oâclock or so. She wanted to sell me a diamond. Real quality stuff, too. I offered to set up a meet, but she wouldnât go for it. She said sheâd make the arrangements.â He lowered his voice. âLook, donât go spreading this around, okay? I donât want people to think Iâm a double-dealer.â He sat cross-legged on the hallway floor. âThe whole scene felt wrong, you know? She didnât seem like the type to be fencing diamonds. I thought maybe it was a cop setup. So I followed her.â
âWhere did
