The first in a series of detective stories featuring Our Heroine, Neve Errong, as she solves problems with cryptology. Can you help Agent Errong crack the codes?

1. The Adventures of NeveErrong* Part I: The World Culprit *Yes, NeveErronglooks a lot like Carmen Sandiego. They’re sisters.

2. From the Desk ofTHE CHIEF Agent Errong, Enemy Agents from that crime-loving confederacy, E.V.I.L.L. have done it again! This time, moments before the final match, those wretched robbers have taken the World Cup from Frankfurt, Germany. Trusty Agent Al Waysright has uncovered two clues: a baffling message and what hopefully will be the key to reading it! Agent, fans of soccer worldwide rest their hope on you. Can you break the code and figure out what we need to do next? Here’s the message: PLLMM DPDYD HWNZG MXLWM YJIGD MLIID WEDW And this came with it: Use the key (7,9) See you soon!

3. Monoalphabetic Ciphers Shift cipher: abcd BCDE (forward 1) hello  JGNNQ (forward 2) Cryptogram: Random assignment N = W V = B Affine Cipher: E(a,b)=(a*x+b)%26 x is the plaintext (a,b) is a secret key a=0, b=1, c=2, … z=25 Input each character x of plaintext into (a*x+b)%26. Each plaintext letter will always change to the same ciphertext letter.

4. Making our new alphabet a=0 b=1 c=2 d=3 e=4 f=5 g=6 h=7 i=8 j=9 k=10 l=11 m=12 n=13 o=14 p=15 q=16 r=17 s=18 t=19 u=20 v=21 w=22 x=23 y=24 z=25 Remember, our key was (a,b)=(7,9) a  (7*0+9)=9%26=9= J b  (7*1+9)=16%26=16=Q c  (7*2+9)=23%26=23=X d  (7*3+9)=30%26=4=E e  (7*4+9)=37%26=11=L f  (7*5+9)=44%26=18=S g  (7*6+9)=51%26=25=Z h  (7*7+9)=58%26=6=G i  (7*8+9)=65%26=13=N j  (7*9+9)=72%26=20=U k  (7*10+9)=79%26=1=B l  (7*11+9)=86%26=8=I m  (7*12+9)=93%26=15=P Can you create the rest of the code on your own?

5. Working Backwards PT  CT ----- a  J b  Q c  X d  E e  L f  S g  Z h  G i  N j  U k  B l  I m  P n  W o  D p  K q  R r  Y s  F t  M u  T v  A w  H x  O y  V z  C We have a coded message. We must take that coded message and change it back into plaintext to read it! PLLMM DPDYY DHWNZ GMXLW MYJIG DMLII DWEDW PLLMM = meett Can you solve the code!?

6. From the Desk ofTHE CHIEF Well done, Gumshoe! We now know we must travel tomorrow to the Central Hotel in London to learn more of this poisonous plot and maybe even intercept the World Cup trophy as it passes between slippery E.V.I.L.L. hands! You’ve done good work, and we’re going to need you on this case all the way through! Do you have the guts, Agent Errong!?
