The library? Mad Jack said. Ya mean to tell me the treasure is hidden in the library?

That's what the map says, said Meg. She tried to hand him the map, but Mad Jack just waved it away. He was a bit suspicious, but since he could not read he had to trust what he was told.

Right here on the map it says library, Meg said. She pointed to a big sign over the building's door. And that sign says library.

It sure does, said Uncle Jim.

The letters on the sign are P-O-L-I-C-E, said Meg. That spells library.

Right then, let's go, said Mad Jack. In his excitement, he bounded up the front steps of the building, threw open the door, and rushed inside.
