Is there something wrong with my decryption using key=9, mod 26? I am new to cryptography and have started looking at some basic encryption. I have the following question to answer:

Decrypt the the following encrypted quotation using key = 9, mod 26:

fqjcb rwjwj vnjax bnkhj whxcq nawjv nfxdu mbvnu ujbbf nnc


So far I have decrypted the message to the following:

Whats in a name arose by any other name would smell as sweet


However, this doesn't seem to make sense as a complete decrypted message - have I done something wrong in my decryption or is my answer correct?
Your punctuation is slightly off:


  What's in a name? A rose by any other name would smell as sweet.


It's a reference to Romeo and Juliet
