Nina, The Pinta, And The Vanishing Treasure (Alec Flint, Super Sleuth) (Alec Flint, Super Sleuth)

4th grader Alec Flint is practicing to be a super sleuth. He's even got a pair of super sleuth pants with lots of pockets to hide his detective tools and a sidekick, Gina, who's a bit bossy, but a really great sleuth and friend. When his dad, a local police officer, tells Alec the Christopher Columbus exhibit has gone missing from the town museum, Alec is on the case!
