# Deciphering a string without spaces

I have a given string:

OPIESTGAEDNOMRALILDCNEELENLWEATWIEEEAUTHATNCDR

I have basically tried everything, which left me with substitution method with frequency analysis, but still stuck since this is almost impossible to approach, anyone out there who would be willing to help me.

Only hint that is given is that it's a quote from either a movie or book.

Frequency analysis tells you ...

... that the letter distribution is typical of an English sentence: Many e's, fewer a's, some t's and n's. The cipher probably isn't a substitution cipher.

The cipher is ...

... is a transposition cipher with a columnar transposition of five columns. You can find the number of columns by trying out several possibilities. Rearrange the sentence:

        O P I E S T G A E D
N O M R A L I L D
C N E E L E N L W
E A T W I E E E A
U T H A T N C D R
(The original columns of the transposition are presented as rows when decoding. Take care to make the first row one character longer, because the message length of 46 leaves a remainder of 1 when dividing by the number of original columns, 5.)
