# Case No. #002

Find the First Two Words in the Secret Message.

## Solving the Puzzle

The second case is a Transposition Cipher. (You’ll really want to check Amy’s notes for this one).

Hint #1 – Read Types of Secret Writing > Transposition

Hint #2 – Specifically Amy’s notes on Rail Fence .

Hint #3 – The first and last rail of a Rail Fence Cipher will always;

• be equal in character length
• or the first rail will be one character longer.

Hint #4 – The Ciphertext is 46 characters long. Even though it’s written in four lines;

• the first and last line are 11 and 9 characters respectively.
• which means it’s not using a four rail Cipher.
• 46 is divisible by 2 and 23. So, the Cipher probably has 2 rails .

Hint #5 – A 46 character two-rail Cipher is arranged by;

• Taking the first 23 characters and spacing them apart by 3.
• Arranging the last 22 characters underneath the first 23.

• With an extra space at the beginning and 3 spaces between each character.

The result can be read as;

WELL DONE WE WILL MAKE CONTACT SOON REMAIN WHERE YOU ARE.

Once you’ve entered the solution, well done , you’ll unlock your second achievement.

# Case No. #003

Once you answer the door NBI agents will shuffle you into a car and drive you to a top-secret location where you’ll obtain your third case file and objective.

Figure Out What Words Three and Four Are.

## Solving the Puzzle

Case No. #003 ramps up the difficulty by combining a Steganography Key and a Transposition Cipher.

Hint #1 – Read Types of Secret Writing > Steganography > Null

Hint #2 – And Amy’s notes on Types of Secret Writing > Red Fence .

Hint #3 – Key (Null) tells us the encryption key is 213 .

Hint #4 – Because Red Fence is just a Rail Fence Cipher with a key;

• We know we’re using three rails
• That rail #1 and rail #3 will have the same number of characters (11).
• And that we need to arrange the rails as; Rail #2, Rail #1 and Rail #3.

Hint #5 – A 44 character three-rail Cipher is arranged by;

• Taking characters 22 to 33 and spacing them apart by 4.
• T K W L T S H W E A U
• Taking the first 22 characters and spacing them apart by 3.
• W N L T I K E I T E T R O I O D R H T O A E
• Taking characters characters 33 to 44 and spacing them apart by 4.
• I E N L L A W N W Y R.

The result can be read as;

# Case No. #46504

Once you’ve answered the door you’ll be recruited to join the NBI. After the cinematic find Mrytle and begin work, on Case No. #46504, at your desk. Find Out Who Rat, White and Night Are.

## Solving the Puzzle

This case is more of a logic puzzle. All you need to do is match the coded name entries in the drug dealers logbook to the names mentioned in the NBI agents notes.

Hint #1 – Black is the only person who stopped buying after April 15th. He must be Jerry who has been in prison since the 17th.

Hint #2 – Rat made the most purchases of any buyer (6) and two the night before Ted was found dead from an overdose. Rat must be Ted..

Hint #3 – Every remaining buyer pays between \$6.30 and \$9.40 per gram except for White. White pays about \$0.50 per gram so he must be Mark, the dealers friend.

Hint #4 – Dry buys about 14g per visit. If we assume the average amount a user buys is the what they use per session Dry should have about 86 grams leftover after three sessions. Dry must be Ivy.

Hint #4 – This just leaves two names left. It makes some sense that a Dog Breeders codename might be Cat.. Or you can just guess until you get it right.

Once you’ve entered the solution;

mark

ted

brian

you’ll unlock the games 4th achievement.

# Case No. #46705

Once you make friends with Hank, grab the case file on your desk, sit down and get cracking.

The objective?

Figure Out;

• How Many Letters the Alphabet Has Been Shifted By and
• What Words 15 and 16 Say

## Solving the Puzzle

This case file uses a shifted alphabet to create the cipher which is possible to solve in just a few steps.

Hint #1 – Read Amy’s notes on Types of Secret Writing > Ciphers.

Hint #2 – Specifically the Caesar Shift Cipher.

Hint #3 – There are only two single words in the English language. So, W11 must be A or I.

Hint #4 – Plugging A or I into the Substitution table test followed by the other letters in Alphabetical order, you’ll be able to read the decoded message.

The result can be read as;

HEY RYAN HERE IS THE PLAN. FRIDAY TWO PM HALLWAY-C.

I WILL PULL THE FIRE ALARM. WE DUCK OUT THE BACK OF THE SCHOOL.

NO TEST FOR US

# Case No. #46806

After a very awkward conversation with your family it will be a new day. Which means a new case on your desk to crack. Figure Out What Words 1, 2, 3, 21 and 22 Say.

## Solving the Puzzle

For this case the Substitution table test is going to be your best friend.

Hint #1 – There are only two repeats in the English language that would fit for W22. ‘EE’ or ‘OO’.

Hint #2 – W17 is a two letter word. Using Hint #1, ‘Q’ must be ‘O’.

Hint #3 – ‘GW’ occurs repeatedly in the text. If ‘Q’ is ‘O’, GW must be a two-letter word like HE IN AN AT and MY.

Hint #4 – If GW is MY, W19 must be MONEY.

Hint #5 – Several words in the cipher are names of people.

After a certain point you’ll be able to guess enough words to complete the puzzle. The result can be read as;

JASON – MY HOUSE. TROY – THE HOLIDAY HOUSE. JUSTINE – MY CAR. CAROLINE TEN THOUSAND DOLLARS. MICHAEL – REST OF MY MONEY. PAUL – COMIC BOOK COLLECTION.

Once you’ve entered the solution;

# Case No. #47007

After an awkward interaction with Sasha there will be a new casefile on your desk to solve. Figure Out The Keyword Used In The Cipher.

## Solving the Puzzle

This case isn’t the hardest to decrypt but identifying the key word being used has caused people a lot of trouble.

Hint #1 – There are only two words in the english language W11 could be. A or I .

Hint #2 – QAE appears repeatedly and is likely a common word like ‘THE’ .

Hint #3 – Pay attention to W25. There are only a few candidates for repeated letters that would make sense in a word this size.

After a certain point you’ll be able to guess enough words to complete the puzzle. The result can be read as;

SARAH WILL PICK ME UP FROM PRISON. HAVE THE CAR I PICKED OUT FOR HER READY. WE WILL BE BACK AT THREE IN THE AFTERNOON.

But we’re not quite done yet. The next step is identifying the key word being used to encrypt the plaintext. Here’s how it works;

The transposed letters in the new alphabet are all in alphabetical order except for C E D B A F G.

These letters correspond to C E I O S T Y respectively.

So, in order A = S, B = 0, C = C, D = I, E = E, F= T and G = Y.

you’ll unlock the games seventh achievement.
