woods.
âCareful!â yelled Frank. âWe donât want to lose her now.â
âRight!â yelled Joe. âAnd Iâm going to try not to lose an eye, either.â
It was hard to see Lucy through the trees. But they could still hear her running. Then, suddenly, the sound stopped. It was replaced by the sound of digging.
âSheâs burying the toy,â said Joe. âBut where is she?â
The boys looked around. There was no sign of Lucy. Then they saw dirt flying up into the air.
âThere!â yelled Frank.
The boys ran over. She was sitting at the bottom of a deep hole, happily kicking dirt around. The hole was filled with things. Aside from Lucyâs favorite toy, there were three tennis balls, two dolls, a book, two pairs of glasses, an empty backpack, and dozens of sticks.
But there was no sign of Frankâs bike.
âDarn,â said Frank. He hadnât really thoughtLucy had stolen his bike, but heâd gotten his hopes up anyway.
âSorry, Frank,â said Mr. Mack, who had just caught up with them. âSo thatâs where my glasses went!â He began to pick all the important things out of the hole.
âItâs okay,â said Frank. âIâm glad she wasnât the one who took it.â
âBut,â said Joe, âmaybe she can help us find out who did take it?â
âWeâd be happy to help you boys any way we can. But how?â asked Mr. Mack.
âWell, sheâs good at finding where she hid all of this stuff,â said Joe. âSo maybe she can track whoever took Frankâs bike.â
âGood idea!â said Frank.
Together Frank, Joe, Mr. Mack, and Lucy all headed back to the last place Frank had seen his bike.
âOkay, Lucy,â said Frank. âI need you to find my bike. Can you do that, girl?â
Lucy whined and sniffed all around where the bike had been. She laid her ears flat against her skull. She put her nose low to the ground. Slowly she started walking away. Frank and Joe followed her down the path. Halfway through the park, she suddenly turned off the path, onto the dirt.
âLook,â said Frank. He pointed to the ground. Lucy was following a set of footprintsâand a bike track!
Lucy followed the tracks across the big lawn. But when they came to the road that ran through the center of the park, she lost them. The ground was drier here, and the tracks disappeared. They searched up and down, but neither the boys nor Lucy could find the trail again. They walked back to where theyâd last seen the footprints. Frank kneeled down and drew them in his notebook.
âIâm sorry to get your hopes up, boys,â said Mr. Mack when he caught up with them.
âItâs okay, Mr. Mack,â said Frank. âLucy helped us more than you might guess. I think I know whose footprints these are!â

So Close and Yet So Far
I âll bet you anything those footprints belong to Adam Ackerman,â said Frank.
âTheyâre definitely the right size,â said Joe. âBut how can you be sure?â
âLook at the tracks,â said Frank. âSee how the left footprints are all deeper than the right ones? They were made by someone who couldnât step as hard on one side as the other. When Mrs. Ackerman took me to the ranger station, she told Adam to stay behind because heâd hurt his foot!â
âLetâs find him!â said Joe.
That turned out to be easier said than done. Bayport Park was large, and Adam could have been anywhere. He might have even left the park already!
The boys decided to start their search where Lucy had lost the trail. They left the road behind and walked deeper into the park. Mr. Mack and Lucy followed behind them until Lucy grabbed a Frisbee and took off running.
âYou boys keep going,â said Mr. Mack. âWeâll catch up.â
The boys walked a little farther
