entered, a young woman with a worried, bunched-up face looked up from her desk.
âMr. Wren, right?â
Mr. Wren grinned his movie-star grin, and Mo could see he was flattered. âHowâd you guess?â
âIf you ask me,â Mercedes muttered, looking around, âthey donât exactly get hordes of customers up here.â
âMr. Buckman Senior is expecting you.â The secretary bit her bottom lip. âIn fact, I better tell him right this minute that youâreââ
The door behind her swung open, and a large belly barreled out. Behind it came a man with a broad red face, wearing a tie the yellow of caution tape.
âMr. Wren! Bob Buckman!â He grabbed Moâs fatherâs hand and pumped it up and down. âI apologize for my assistant keeping you waiting!â
The secretary reddened. âIâm sorry, Iââ
âItâs so hard to get good help these days.â Buckmansaid this to Mr. Wren as if it were a great joke.
Mr. Wren frowned. âWe just got here.â
At the âwe,â Mr. Buckman noticed the girls for the first time. He swung back around to his secretary.
âTake good care of these children while we confer.â He gestured toward his inner office. âThis way, please!â
Mr. Wren threw Mo an inquiring look, but when she gave him the thumbs-up, he and Mr. Buckman disappeared through the door, which shut behind them with an emphatic click.
The secretary pulled open a drawer and produced a bag of peppermint patties. âHeâs mean,â said Dottie, helping herself. âYouâre nice.â
Mercedes paced up and down the roomâapproximately seven paces each way. The carpet was worn, as if lots of people had paced here.
âIf you donât mind my asking,â she said to the secretary, âare there really two of them?â
The woman smiled for the first time, showing dimples in both cheeks.
âTheyâre clones, only Juniorâs even stingier. Whoops, did I say that?â
Mo looked out the window, whose sill was speckled with pigeon poop. The clouds still hung heavy and dark.
âAnd whatâs their business again?â Mercedes kept her voice cool, as if these were just idle questions to while away this boring time they had to wait
âDevelopers. They buy and sell. Or, as Mr. B Senior likes to say, they turn things around.â She chewed her lip. âOr upside down. Or inside out.â
Dottie helped herself to two more chocolates. âHeâs mean. Youâre nice.â
The secretary unwrapped a patty for herself. âNo comment,â she said.
âWhy do you think heâs so interested in a little house on Fox Street?â Mercedes went on.
âItâs not so little,â Mo couldnât help saying.
The secretary gnawed her bottom lip. Lipstick and chocolate flecked her teeth. âThatâs confidential information.â
The phone rang.
âYes, Mr. Buckman,â said the secretary. âNo, Mr. Buckmanâ¦today? This afternoon? But you specifically said the deadline wasâ¦Yes, yes, I mean no, noâ¦â
Mercedes halted in front of the desk. Time was short. Mr. Wren might be out any minute. She raised her chin, doing her steeple imitation.
âIt doesnât make sense that theyâre so eager to buythe Wrensâ house,â she said as soon as the secretary hung up. Her voice was low and calm. Here at last, the Mercedes Mo knew! Loyal. Courageous. Smarter than nine out of ten grown-ups. Moâs ancient love for her friend came rushing back. âI get the feeling something shadyâs going on. But you donât seem like a shady person to me.â
The secretary looked insulted, then pleased, then confused. âI just work here. Do you have any idea how hard jobs are to find?â
Mercedes clasped her hands to her chest. She nodded toward Mo and Dottie.
âTheyâre motherless,â she
