The answer is the letter 'N'.

The riddle says 'take me out of a window and I leave a grieving wife'. Now if you think carefully and analyze some of the words in the sentence, you will find the answer to the whole riddle. In this case, the word is 'window' and if you remove the letter 'n' from the word, the word will become widow (I leave a grieving wife). Now the first sentence will make sense as if you read.

he second sentence says 'but stick me in a door, and I can save somebody's life'. Now in this sentence, the word 'door' is the one you need to analyze. If you add the letter 'N' in the word door, it becomes donor(I can save somebody's life). Did you answer this riddle correctly?
