The Big Reveal Carter reached out and felt around for his cell phone on the desk by his bed He opened his eyes to slits trying not to let too much morning in Finally his hand hit the phone Who is texting at dawn on a school-free Friday he grumbled as he held the phone close to his nose to read it The first thing he noticed was that it was ten o’clock Okay he thought dawn came and went a while ago Carter blinked as he tried to make sense of the message It was from Uncle Dan and looked like random numbers and letters a9i9 3o19e21o35 Carter moaned There was no way he could 4
do this one in his head He’d need paper That meant getting up He closed his eyes for a moment wondering what would happen if he just pretended he hadn’t heard the phone He could go back to sleep Then his stomach grumbled Okay okay he muttered as he sat up He swung his long legs over the side of the bed Carter copied the letters and numbers onto a sheet of paper It was obviously a code Uncle Dan loved codes They fed his need for security and offered a mental challenge Uncle Dan was always in favor of a mental challenge Carter figured this was probably some kind of substitution code In a substitution code some or all of the letters are replaced by numbers Immediately he noticed that all the letters in the code were vowels That meant the code might only represent consonants Carter chewed his lip as he studied the paper He wrote out the most common substitution code that only used consonants 5

based on a book Carter thought about the last few weeks as he pulled on a pair of jeans After they’d finally caught the hacker who wanted to destroy Uncle Dan’s invention the finishing touches on the project went fast Then Uncle Dan had looked for a place to exhibit the finished product When his stomach grumbled again Carter decided he’d better feed the beast before dashing off to Uncle Dan’s house When he hit the kitchen he spotted the green and white box on the counter Yes Doughnuts He flipped the lid back and scowled There were mostly raspberry jelly doughnuts yuck He nudged aside two plain cake doughnuts boring Then he found a lone chocolate and snagged it Uncle Dan would just have to fill the rest of his junk food needs As he hauled open the front door he heard his mom’s voice Is that you Carter Yesph he said around a mouthful Your dad wants you to mow the lawn 7
