The above is a clueless crossword. Basically, you have a crossword grid and you have to fill in the blanks so that every across & down contains a legible word. There is one catch, however, you are only allowed to use each letter of the alphabet once. It's tougher than it sounds.

Solvers Note: Since puzzles like these are VERY hard to make, I've had to use a couple of words which may not immediately leap to mind. The first of them is a french phrase that is commonly used in English (For example, C'est la vie), the second is the name of a river in Greek mythology.

To help you, I have given you one letter, S which is the first letter of the word from Greek mythology. The letter X is being used in place of a blank square in a normal crossword and the X you can see t here is not part of any word. There is another letter X in the crossword.
