“We do!” Imani ran to the kitchen and came back with a drawing of the first-floor rooms. “It’s a bit smudged,” she said, pointing to several numbers.
“That’s OK,” Caleb replied. “To find the secret room, we need to measure the walls of the house and compare them with the measurements on this blueprint. If measurements don’t match up, we know something is hidden!”

“Let’s check this one first,” Imani suggested. “This wall is supposed to be 13 feet long.”
Jo placed one foot in front of the other as he walked along the left wall. “A little more than 19 steps,” he said.
