Think I know what the encoding on the string actually is but there are to many characters once converted.

Okay, I got the first code, I know what it is, I noticed a missing letter and now what?

Is it connected to a special book, or I started to search clues madly?

Tried everything, deciphered the text, but don't know what to do with the numbers :( ! I give up

I guess it uses a cipher like a polybius square, but I'm missing something because there are too many numbers...

I'm Starting to think that when he said "Here is the key" in the comment, he wasn't refering to the code, but to the key to solving the polybus square...If you add up a "Key", numbers can easily exceed 24... wich would explain

I'm still on the book track, and it's getting hotter and hotter... Until I get to the numbers, because I don't know what to do with them.

Well ... This is the result of what I found.

In the above sentence, there's a letter missing. The first letter.
If you convert it, the letter M for Mr is missing.
Now if you count the number of letters, it gives you 38 letters, the same number of numbers found below.
Since he said that this was the key, I transformed the above letters into numbers, and substracted them to the already given numbers...

it gives me the following numbers : 16 24 20 22 57 63 30 1 27 13 66 20 43 76 40 58 69 65 -9 36 41 17 39 53 45 4 -27 75 6 74 42 35 85 15 49 30 67 57 15


I am lost at this point... as if I retain the useful numbers, I obtain 11 letters over 16 ...

Don't forget the three last words that follow the panagram sentence. I thought maybe it had something to do with square root? But anyway, I was too tired to think the puzzle further.

There are 39, not 38 numbers. :)

I was also thinking, that because of the panagram, maybe Namegoo added duplicate numbers there and they should be removed. That's just guessing, though.

Well at this point, it could me anything...
Gonna wait for more details :) otherwise might take an eternity to solve.

No one got it yet. ;)


And if the gift code was different, there might be less numbers or more of them...in the end it doesn't make a difference when solving the puzzle.

At least tell me if I'm on the right track with the book :)

As far as I'm aware, it's not connected to any books.

Oh. Now I absolutely have no idea...
You know, when I solved the first sentence, and searched for it on the net, it resulted in a book: Ella Minnow Pea. The story takes place on an island with a pangram on it, and the letter Z falls from it... And the missing letter in the decoded sentence is M; it would be Z in the original one. So, when I noticed the Z fell down here too I was sooo happy... D'oh.
