If you missed Monday, Tuesday, Wednesday and Thursday's challenges, there might still be time to solve them all. No one knows how long it'll take for one of you trivia junkies to nail down the whole megillah, so make haste, make haste. And now, on the next page, I present the final puzzle, drawing on all the answers you dug up along the trail.

Day 4: Looking for first and last name of the ballplayer in question. His first name is the diminutive form of the first name of the second president from yesterday's challenge. His second name is the first name of the first president, in plural form, from yesterday's challenge. Who is the ball player?

Day 2: On Tuesday you were asked a series of questions about a diagram. What is the number that goes in the blank square to complete the diagram?

Day 1: On Monday you had to identify 5 mystery tunes. Each tune was by a band that got its start in what city?

Day 3: On Wednesday you were asked to name the 10 states listed in the word puzzle. One of the states you should have found is also the first name of a city in Missouri. What is the full name of that city?
