“nicely done tim! you’ve got the code! do you want to open the safe?“
“yes!”
“where is it then?“
“behind the bookshelf.”
“behind it?“
“yes, push the book!”
“what book?“
“atlantis!”
“oh, you mean this?“

“push it!”
“no, you push it!“
“good! did you hear the clicking sound?“
“yes!”
“that means you can open the shelf now, just pull that side...
…good, do you se the safe?“
“yes! 15365263.”
“that’s right. what do you see inside?“
“the papers.”
“what papers?“
“with the codes!”
“yes, that’s right. with the codes. what are those again?“
“codes to find the missing gold!”
“well, yes, i believe so, but i am not sure.“
“that’s your code.”
“yes! that’s right, that’s the bergman-code. but can you see it?”
“no!”
“why not?“
“because the wrote it inside the paper.”
“inside the paper you say?“
“you need to hold it against the light to see it.”
“ok. let’s do that! what does it say?“
“th0c76zgb54njlox8se3ukq1m2idrwpavf9y”
“that’s right, a rather strange code, isn’t it?“
“tell me about the others.”
“what others?“
“on the other paper.”
“ok, I’ll do that. we are a few who have found codes like this. all similar in structure. all the letters of the alphabet and all numbers, but only appearing once. the other six codes that has been found are on this piece of paper. many do not believe there is anything to it. but i believe they might unlock secrets.“
“the gold.”
“that’s right. i believe that they indeed will reveal the location of a big treasure with a lot of gold.“
“tell me how, grampa!”
“well, i am not sure, but there is a rumor of a secret code machine, a prototype of the nazis coding machine enigma.“
