looked as if theyâd been smudged with brown ink, and they smelled like chemicals.
âHow did you get your hand so dirty?â Cody asked.
M.E. shrugged. âI donât know. All I did was pick up that artifact. I donât remember touching anything else.â
Cody looked at her three code-busting friends. While the other students stood across the room listening to Dr. Jordan talk about one of the artifacts, Cody stole over to the case again. She glanced around, then pulled open the unlocked door, reached in, and ran her index finger over the top of the Eye. Removing her hand from the case, she closed the door, then held up her hand.
Her fingertip was brown. The same shade of brown as the amulet.
âGuys,â she whispered. âI donât think the color is supposed to come off like that.â
M.E. checked her hand again, then looked at the others.
âDo you think that Eye is a fake?â Luke asked.
Cody shrugged. âWhat do we do? If we tell the museum people we touched it, we could get in trouble. But if itâs a fake, wouldnât they want to know? The forger could be a thief, and get away with stealing valuable art.â
âThat writing on the bottom was weird,â M.E. said. âAn eye for an

?â
âShh!â Quinn said. âDr. Jordan is watching us again. Iâm sure he thinks weâre up to something. We need to move.â
Cody turned around and saw the museum guy staring at them strangely. A chill ran down her back. âCome on, itâs time to turn in our assignments to Ms. Stad. Weâll figure out what to do during lunch. Follow me.â
Cody led her friends out of the room and into the lobby, where other students had alreadygathered with their teachers. Luke and Quinn joined Mr. Pikeâs group, while Cody and M.E. headed for Ms. Stadâs class. When all the students were seated on the floor, Ms. Stad asked, âSo, did everyone find all of the Eyes of Horus in the museum?â
Hands shot up.
âHow many did you find, Ryan?â she asked the blond kid with glasses, sitting in the middle.
âEleven!â
âGood,â Ms. Stad said. âAnyone else find a different number?â
âOur group found twelve,â said Stephanie.
âNice,â Ms. Stad said. âAnyone else?â
M.E. raised her hand. âWe found thirteen.â
âWow!â exclaimed Ms. Stad. âAre you sure?â
M.E. nodded and held up her paper.
âWell, believe it or not, our parent volunteers only found twelve when they counted them earlier,â Ms. Stad said. âI guess your group found one we missed. Hmm. I wonder if the number
thirteen
is a coincidence.â
Cody remembered the number of thirteens theyâdfound on the dollar bill. Interesting how that number kept coming up.
âDid you know that many cultures consider
thirteen
a number associated with luck?â Ms. Stad asked. âSome say the Egyptians were the first people to become superstitious about the number. They thought it brought good luck and immortality, and was related to the thirteenth stage of lifeâthe afterlife. Later, the number was associated with death. Other cultures think the number brings bad luck. Can you think of some examples of bad luck associated with
thirteen
?â
Lyla raised her hand. âFriday the thirteenth!â
âYes!â Ms. Stad said. âSome people believe thatâs an unlucky day.â
Bradley raised his hand. âMy dadâs office building doesnât have a thirteenth floor because itâs supposed to be bad luck. It just goes from twelve to fourteen.â
âGreat example,â Ms. Stad said. âMany hotels, apartment buildings, and office buildings donât have a thirteenth floor. Isnât that interesting?â
The students grinned and nodded.
âBy the way,â Ms. Stad continued, âmany of you students are thirteen years old. How many
