She held up a large sign written in Morse code. âAll right, letâs see if you can decipher this message. If you need help, just look at the poster on the wall.â

The students began cracking the coded message. Quinn and Cody were the first to raise their handswhen they finished. Ms. Bishop called on Quinn and he recited the answer.
âGreat job!â Ms. Bishop said. âDid you know that Morse code was developed in the 1800s by an artist and inventor named Samuel F. B. Morse? He worked with a physicist to create an electrical telegraph system which was used to send encrypted messages between warships, naval bases, and railroads. Sometimes Morse code was used to send distress signals. The most famous one sounds like this.â Ms. Bishop gave three rapid knocks on the nearby wall, then three knocks spaced a second apart, then three more quick knocks.

âDoes anyone know what that means?â
Hands shot up. Cody and her friends immediately recognized the distress signal from when Ms. Stad taught them Morse code. Ms. Bishop called on a boy named Ty from Mr. Pikeâs class.
âS.O.S.,â Ty said.
âAnd what does S.O.S. stand for?â Ms. Bishop asked.
âSave our ship!â a girl named Tessa called out.
âSave our souls!â another boy named Max offered.
âSave our shoes!â Matt the Brat yelled, then laughed at his own joke.
Ms. Bishop ignored Mattâs contribution. âYes, itâs come to mean âsave our shipâ or âsave our soulsâ. But do you know what that
really
means?â she asked, grinning.
âHELP!â called out several students, including the Code Busters.
âCorrect!â Ms. Bishop said. âS.O.S. is not really an acronym. The letters S and O were chosen because theyâre easy to use and remember in Morse codeâjust three dots and three dashes. So, if youâre ever in trouble, just tap out S.O.S. and, hopefully, someone will come rescue you!â
Cody heard several students tapping the S.O.S. code on nearby walls.
âAll right, everyone,â Ms. Stad called out, âQuiet down, please.â
Ms. Bishop smiled. âAt the end of the tour, youâll get to learn about the history of espionage and how spying was used in the Revolutionary War, the Civil War, and both World War I and II. When you leave the exhibits, youâll have a chance to go to the Spy Store and pick out some spy gear. Once youâre finished shopping, find your teachers, because youâre going on your very own Spy Hunt mission. In groups, you and your chaperones will explore the Washington Mall seeking out mystery locations with the help of GPS-guided clues.â
Once Ms. Bishop finished talking, it was time to get started. Cody and M.E. buddied up. So did Quinn and Luke. Even Matt the Brat had a buddyâa girl named Sadie who was his next-door neighbor.
Cody noticed that the new girl, Mika, was by herself. She remembered what it was like when she was new and didnât know anyone. It took a while to make friends, and she felt lucky to have her Code Busters Club friends.
Cody went over to her teacher. âMs. Stadelhofer? Mika doesnât have a partner. Can she come with M.E. and me?â
Ms. Stad looked around to see if anyone else needed to pair up, but all of the students had partners. âWell, I suppose she could be my buddy, but sheâd probably have more fun with you girls. Thanks, Cody. Thatâs very nice of you.â
Mika was standing at the back of the line next to her mother, who was one of the chaperones.
âHey, Mika. Ms. Stad said you could join M.E. and me if you want.â
Mika smiled widely. âThanks!â She turned to her mother, who nodded, and then followed Cody to where M.E. stood in line.
âHey! No cuts,â Matt the Brat called
