Into the Wardrobe

I am looking for a Lewis quote that I had read in another book, but cannot find it and was hoping someone could help. It is in reference to Lewis catching a particular aroma (of flowers or something?) and that aroma provoking a very powerful rememberance of his childhood days.

Anything that anyone can do would be appreciated.

Thanks,
JK

You are, without a doubt, the man, Sven. Good show, chum!

Thank you very much.
