Breaking the Cipher
Dev Chaudhry joined the school code club to dodge detention, not to crack anything. Then he finds the Tillery Cipher: five lines of nonsense, framed on the wall since 1991, never solved. Each answer leads to another lock, from a hidden strip of Caesar’s alphabet to a dusty library, a lamp-bearing legend, and a hallway the wrecking crew will flatten in three weeks. Dev wants the win so badly he can taste it. But the cipher keeps asking a harder question than “what does it say?” It asks who gets to sign it. Ages 11–13. Readers quietly learn how Caesar, Polybius, Vigenere, scytale and Atbash ciphers work and how codebreakers...Copper Seal · Certificate Nº 0083-6AIBOOKS · booksai.store
Breaking the Cipher
by Carter Luense
Some secrets take more than one solver
Dev Chaudhry joined the school code club to dodge detention, not to crack anything. Then he finds the Tillery Cipher: five lines of nonsense, framed on the wall since 1991, never solved. Each answer leads to another lock, from a hidden strip of Caesar’s alphabet to a dusty library, a lamp-bearing legend, and a hallway the wrecking crew will flatten in three weeks. Dev wants the win so badly he can taste it. But the cipher keeps asking a harder question than “what does it say?” It asks who gets to sign it.
Ages 11–13. Readers quietly learn how Caesar, Polybius, Vigenere, scytale and Atbash ciphers work and how codebreakers use brute force and letter frequency, along with why giving honest credit and admitting mistakes matter.
