They are already slipping the body into a bag when you arrive on the scene. Your partner is supervising. He approaches as soon as he sees you.
"Well, you're late!", he says, smiling. "But it doesn't much matter on this one. It's an open and shut case. The victim was John Kahn, shot in the head at close range. His girl friend, Brenda Fortune, was found on the scene, a gun registered to her was nearby and had been recently fired. I don't think there is much question of the ballistics matching up. And her story stinks. Claims she was kidnapped by some guy in a mask who took her gun and shot her boyfriend then ran off. The guy last week was more entertaining. You remember? The one who said it was actually his clone, made by the North Koreans no less, who had done the crime. This girls story holds up about as well, and is less entertaining. Classic lovers quarrel. She'll be taking a lethal injection for this one."
Your partner shakes his head for a moment, then continues. "Oh well, nothing else. Oh! Except for this!" then he pulls a very small notebook out of his pocket and hands it to you. "This was in the guys jacket. It's just gibberish, random doodles, I doubt if it will be any help. Besides, we KNOW what happened here."
As your partner walks away, you glance at the notebook. It's filled with several pages of letters and numbers, none of which seem to make any sense at first glance, but random doodles?, no, they don't look random to you. You get the distinct sense of pattern here. Open and shut case huh? Well, there just might be a lot more information on this case then your partner managed to uncover...

[hint 2]
Its a transposition cipher of a very specific historical type.
[/hint 2]

[hint 3]
This message is 274 characters long. That leaves only two factors, 2*137. So you need to try a 2*137 square, and a 137*2 square. Make certain you read each square BOTH WAYS, by collumns and by rows.
[/hint 3]

[hint 4]
This transposition is often called a "rail fence" cipher. Think of it as just a matrix cipher with a period of 2. You encrypt SEND HELP AT ONCE in rail fence(2) as:
SNHLAOC
EDEPTNE
(sorry I can't line it up because you can't set colors inside of code tags)
resulting in SNHLAOC EDEPTNE
There are more complicated ciphers that are called "rail fence". Some of them are just regular matrix ciphers with the plain text written in by collumns and pulled off by rows (the opposite of regular columnar transposition) with any any depth you want. The nasty ones write in by diagonals, that puts more letters in some rows than others. Yikes!!! I didn't do ANYTHING like that to you. just simple rail fence with a depth of 2.

The frequency count came out a bit odd, but this IS just a transposition cipher.

It's a matrix cipher. Find the all factors, place the letters into the matrix and then check both rows and collumns to see if you have found the message.

There are only 3 factors, 3*11*11=363
So the matrix must be one of: 3*121 or 121*3 or 33*11 or 11*33
Try all four, and then play with decrypting each. Three of the possibilities should prove dead ends very quickly. You can check digram frequencies to see try and eliminate the incorrect matrixes as well.

[hint 1]
It's a transposition cipher
[/hint 1]

[hint 2]
It's a simple matrix cipher with a keyword. The message was written in by rows and pulled off by collumns in order of the keyword.
You can attack this with multiple anagramming. Try a valid matrix, then see if you can make "anagrams" from the letters in each row. If you find something promising, re-arrange the rows and see if that makes more of the message appear.
From rot13: This transposition is what the ACA calls a Complete Columnar transposition.

This explains exactly how the encryption algorithm works, you really should look at this hint. It's needed.
[hint 1]
It's a Quagmire 2.5
The plain text alphabet is unkeyed, the crypt alphabets are keyed, all with the SAME key. So, for example, if my alphabet key was CRYPTO and my period key was SPAM, my alphabets would look like:
ABCDEFGHIJKLMNOPQRSTUVWXYZ
--------------------------
SUVWXZABDEFGHIJKLMNCRYPTOQ <-key=Crypto
PTOQSUVWXZABDEFGHIJKLMNCRY <-key=Crypto
ABDEFGHIJKLMNCRYPTOQSUVWXZ <-key=Crypto
MNCRYPTOQSUVWXZABDEFGHIJKL <-key=Crypto
^
|
\-Period key is SPAM,
first letter of plaintext will be encrypted in the S alphabet, 2nd letter in the P alphabet, etc. Just as you would expect.

NOTICE! If you figure out the Vigenere/Quagmire period key, you have the "A" values for each alphabet!
[/hint 1]

This hint gives directions on how you can place one of the obvious cribs.
[hint 2]
If you compare the period of this cipher to the last, and consider the inexperiance of the encryptor, you might be able to guess the vigenere/quagmire period key. That gives you all the "A" values for each of our alphabets. Fill in those A values.

Now, the topic of page 8 makes it clear that we can expect the name of the girlfriend to appear in this message. Since we have all the "A" values, we know each place that her name could fit. We could check them all, but if we are LUCKY, there will be one very obvious fit. That would be if the plain text word name happened to line up with the key. We do have a 3 places where it might fit lined up with the key.

Now, unless "B" or "C" happen to be in the keyword used to scramble the alphabets, there is a very good chance that for the "B" alphabet plain text "b" translates to crypt text "C". IF one of our three possible line ups for for the girlfriends name has a crypt text of C under the B key, then we have probably identified our word. And one of them does.

Which gives us our crib. And a nice start on the crypt alphabet.
[/hint 2]

This gives you a second explicit crib. You CAN break the cipher without this extra crib, using the technique mentioned in hint 2 and going on from there. But it is VERY difficult to do so. So looking at this hint is also highly recommended.
[hint 3]
look for the crib: "FRIGHTENEDBRENDA"
[/hint 3]

This is a standard 5x5 PLAYFAIR cipher. I don't consider this a hint because that information was supposed to be available on Page 9 and got lost when I was trying to simplify page 9.

There is a good playfair crib in this message. It's not REAL obvious from context that it will be here, but you can possibly figure out what the crib is for yourself by looking over all the previous messages and examining important phrases to see if any make good playfair cribs. I used the only one that seemed useful to me.
This cipher IS breakable without the crib using shotgun hill climbing or simulated annealing. There is a program available online that cracks this playfair in about 2 seconds using simulated annealing. But where is the fun in that? (unless you wrote the program!) :) Now doing shotgun hillclimbing or simulated annealing by hand is certainly possible, but it's a long painful process. So I recommend you either write a program to do it or use the crib. The crib is really MUCH more practical for this kind of challenge.

This first hint just tells you how many characters are in the crib:
[hint 1]
The crib is 21 characters long, not counting spaces
[/hint 1]

And this gives you a more detailed hint as to what the crib was:
[hint 2]
The place the courier was delivering too.
[/hint 2]

These are some further cribs. They are not as good as the above because they don't have easily detectable digram patterns, but, if you are needing more help filling in the Playfair square, you may be able to place these in the text by exclusion (no letter can encrypt to itself in a playfair) and by digrams you have already revealed.
[hint 3]
The items that are causing all the fuss (13 characters)
The way the money went (23 characters)
First names that make sense in context. (both repeated more than once)
[/hint 3]

This explains exactly how the encryption algorithm works, you really should look at this hint. It's needed.
[hint 1]
Identical to Page 9, but the alphabets are each keyed with a different word, so it might look like:
ABCDEFGHIJKLMNOPQRSTUVWXYZ
--------------------------
STUVWXYZABCEFDOGHIJKLMNPQR <-key=DOG
PQRSCATUVWXYZBDEFGHIJKLMNO <-key=CAT
ABCDMOUSEFGHIJKLNPQRTVWXYZ <-key=MOUSE

\-Period key is still SPAM

NOTICE! As with page 9, if you figure out the Vigenere/Quagmire period key, you have the "A" values for each alphabet!
[/hint 1]

There is a good crib in this message. It's reasonable in context. You may be able to find it for yourself by looking through the previous messages for important parts that would make good cribs at this ciphers period.

This hint just tells how many characters are in the crib:
[hint 2]
The crib is 14 characters long, not counting spaces.
[/hint 2]

This hint give more explicit guidance towards finding the crib:
[hint 3]
The full name of the bad guy.
[/hint 3]

There is another crib that appears TWICE in this message. But it's not as good because it's pattern has a lot of false positives. However, it still may be useful to you. This crib does not appear in exactly this form elsewhere in the journal, so the hint just spells it out exactly.
[hint 4]
video tape
[/hint 4]

And a final hint that might help, but doesn't need to be whited out!
Don't forget to try and guess the Vigenere/Quagmire period key. This guy isn't very good at picking keys, and once you have placed the first crib, you will have a few letters of the key to work with.

"Notebook" is one word.

Ha! 3 of them in a little over 20 minutes. And you were probably reading the newspaper at the same time. :) I suspect they make take less experienced cryptographers a little be longer then that, but they are certainly doable.

It won't keep you for long. Just remember that these start simple and work up from there. You know what KIND it is, try the methods that someone reading a cryptography book for the first time would learn first.

The messages also often give hints about each other. Page 4 gives you a subtle probable word hint to page 3. (It was ACTUALLY supposed to be a hint from page 3 to page 4, but it will work just as well in reverse) :)

Well for page 3, take a look at the letter frequencies, they should be pretty familiar. They should tell you what HASN'T been done to the letters.

Next, there are 274 letters. 274 = 2 * 137. That doesn't lend itself well to making squares.

There are clues built into the context here.
From the frequency count you know what KIND of cipher it is.
Pick up any book that mentions that particular kind of cipher and see what method they describe first. :)

You scared me half to death! :scared:

I checked and double checked all of these to make certain there weren't any typos! And there isn't. Well, at least THIS one isn't. :) Just a very unwise decision that slipped through. That's not a word with the TH missing, that's an acronym for something that was referred to previously.
I should have spelled it out. It just didn't occur to me that it could be turned into a word so easily and appropriately.

Now THERE is a nice clue for anyone working on page 7. :)

So does this mean you breezed through 6 already as well? I thought those two might hold you guys up for a little while. Apparently not! (Although page 6 LOOKS a lot more difficult than it actually is) I know they would have slowed ME down. As always, you guys are GOOD!

And I have worked in the financial industry before, too!

Ah, then you can probably tell exactly how improbable this story is. I, obviously have NOT ever worked in the financial industry. :) Which shouldn't affect the cryptography luckily.

It was very kind of you to put clues to the next cipher type in some of them. They get tougher and tougher.

Yeah, that was the idea. And I figured that page 6 and page 8+ all needed pretty direct hints to at least the method (as well as probable word clues and some of them have really obvious passwords)

Finally found the time to crack page 3. (Sorry - today has been a bit busy.)
