The Seventh Plank on the Ferry Dock
Every summer, the old ferry dock had a game. The dockmaster, Ms. Alba, left a clue on a card by the ticket booth. This year, the card read, "Count from the red lantern. The seventh plank is not what it seems."
Pia and her brother Leo walked to the red lantern at the end of the dock. They counted the planks aloud, one by one, all the way up to seven.
The seventh plank looked just like the others. Pia knelt down and pressed on it. Nothing. Leo pushed on one end, and the other end tipped up like a seesaw.
Under the plank was a dry tin box. Inside it sat a small pair of binoculars and a note. The note said, "For the first sharp eyes to find me. Use them to count the boats."
Pia and Leo took turns looking across the water. They counted nine sailboats and one slow green barge. Then they wrote their names in the little notebook at the bottom of the tin.
