eighth person is!â he announced.
We turned around and quickly counted.
â Sidney! â everyone replied.
Sidney was clapping his hands and jumping up and down.
âSave your energy,â Mary said. âHarry botched up his last case, remember?â
Sid stopped jumping and made a face.
One by one, Mrs. Funderburke handed us our blue lunch tray with a milk carton on it. A few people asked for juice instead. One by one, the cafeteria aides added a large square of pizza, a bag of carrot sticks, a plastic container of applesauce, a big chocolate chip cookie, and a packet with a spork and napkin.
When we got to our lunch table, I checked under my milk carton. The orange sticker wasnât there.
âBoo again!â Mary said. âI donât have it!â
âMe either,â Ida said.
Mary lifted up Harryâs milk carton. âHe doesnât have it!â
â I do! â Sidney said, ripping it off his lunch tray. He held the orange star sticker high in his hand. âIâm getting a gold coin!â
âWell,â Harry cooed. âLike I said, Sidney was the eighth person in line. What do you have to say, Mare?â
Mary slowly sank down in her chair. In a very soft voice she said, âYou got it right this time.â
We all clapped for Harry.
Harry took a bite of pizza and leaned back in his chair. He was feeling good!
âSo, how come you didnât stand in the eighth place in line, Harry?â I whispered. âYou could have gotten that gold coin.â
ââCause solving a tough case is the best prize of all,â Harry said. âCracking a code beats getting a light-up Wiffle Ball.â
I nodded.
Harry wasnât just a real detective. He was a real winner.
A real winner doesnât need a prize.
Epilogue
M rs. Funderburke used these Fibonacci numbers for her February fun: 5, 8, 13, 21. She was planning to make 1 her next number after 21.
But Maryâs tattling changed that.
Mary waited three days before she tattled again. And when she did, it was to Mrs. Funderburke. âHarry knows your special set of numbers,â Mary said. âHe cracked the code. But he doesnât tell us until weâre all lined up, and he never stands in the winning place.â
Mrs. Funderburke said Harry was an honorable detective. But she would no longer use the Fibonacci numbers. She was just going to pick a number out of a jar.
Harryâs reign as the worldâs second-best detective only lasted four days. But he loved every minute of it!
Who was Leonardo Fibonacci?
L eonardo Fibonacci was a famous Italian mathematician who lived from around 1175 to 1250. He recorded a unique sequence of numbers found in patterns in nature and musical chords: 1, 1, 2, 3, 5, 8, 13 . . .
How did Mr. Skooghammer teach Harry the Fibonacci numbers?
In the book Horrible Harry and the Dungeon , Mr. Skooghammer taught Harry about the Fibonacci sequence. He showed Harry things from nature like pineapples and pinecones that illustrate this number pattern.
Starting with this sequence, you can figure out the rest of the pattern: 1, 1, 2, 3, 5, 8, 13, 21 . . .
You add the last two numbers and the sum is the next number. So one plus one is two, one plus two is three, two plus three is five, three plus five is eight, five plus eight is thirteen, and eight plus thirteen is twenty-one!
Can you guess which number comes next?
Can you write the Fibonacci numbers up to almost one thousand?
