Challenge Two

Seems like Aunt Aggie has ambition. I like that in a dame. What she didn't have back then was sophistication. Any damn fool knows that leaving word structure weakens a cipher and makes the Caesar shift pretty straightforward to crack. You can see from this next page in her journal that she got sophisticated pretty fast, and I figure maybe she had something more important to hide in this part of her diary. Who knows what? Maybe she's rude about her brother, but I figure that with her ambition she's figured something out about the Babylon Stone and she doesn't want to share. See what you make of it. You have one week, more or less. Actually, make that less. The deadline is midnight next Wednesday, but I don't want your mothers writing to complain that you stayed up to do it!

Just like before I have five cash prizes. I'll choose five of the first fifty correct answers and dole out fifty pound cheques next week. Got a little extra for the rest of you too. Since it's a little harder, this week we are giving away 500 copies of Simon Singh's CD - The Code Book on CD ROM - courtesy of IBM.

Don't forget though. Speed isn't everything. Your score for the overall Championship prize is based on your first submission for each challenge, so take time to get it right.

We'll try and get some feedback to you early next week, so you can try again if you make a mistake.

Good Luck,
