The Answer to the Hint Code(Day 1)

"Substitution...?" you asked again, slowly.

Detective W nodded. "That's right. Substitution. It's a substitution code. Professor Cho was gracious enough that he gave another hint."

You looked at the fly. Well, my little buggy friend, what kind of hint are you? you thought.

You wracked your brain for any clues. You remembered that during high school, a cryptogram enthusiast worked with you for a group project in math class. He had shown you some simple substitution codes.

"... So, you see, you substitute the words in front of the original alphabet, and then replace the remaining letters on the alphabet. But, the replacement has to be in order. You understand?"

With hesitation, you began writing on the notepad. If I remember correctly...' you thought. 'What if the substitution word is "FLY"?

You wrote the alphabet on the top, and the replacement alphabet on the bottom. You got:

ABCDEFGHIJKLMNOPQRSTUVWXYZ

FLYABCDEGHIJKMNOPQRSTUVWXZ

If S actually stands for T in this case... you thought as you continued writing on your notepad, Then the answer should actually be... this!

SEB FKLBQ CJX , OFDB SEGQSX CNTQ, OFQFDQFOE NMB

Should actually be: THE AMBER FLY, PAGE THIRTY FOUR, PARAGRAPH ONE

"Ah!" You exclaimed. "The Amber Fly, page thirty four, paragraph one!"

"Ah! That's Grandpa's favorite book! He used to read it to us for bedtime!" Ha-Eun suddenly exclaimed. "That book should still be in Grandpa's library. I remember seeing it every time I go there!"

"Cool," Detective W agreed. "Whenever I went to his college office for office hours, he always had this book on his shelf. I asked him, 'Why do you have a children's book on your shelf?' He told me, 'W, this book is inspirational to me.'"

"So, what does page thirty four, paragraph one says?" you wondered.

"I totally don't know! But, everything will be revealed once we go there! Ha-joon, Ha-Eun, you said the will reading is to be held this Sunday?"

They both nodded.

"Fantastic! Send me Professor Cho's former address, and I will see you on Sunday! Thanks for relying on me, Ha-joon, Ha-Eun!" Detective W beamed.

Ha-Eun smiled. It was the first time you saw her smile.

"Yep, see you, Detective W! And the assistant! See you guys at Grandpa's house on Sunday!"
