How about an I?

I write the whole thing out and then the puzzle underneath it.

I do the same thing; and I'm so afraid of not deleting it before I post it!

yeah I already saw it this time!

before I realized it I guessed the last three words, the first two words had me puzzled, so I went and got the proper book. Now I can't guess anymore.

X,R

I guess N

how about a G?

"Distinguished, fiddlesticks!" said Aunt Letty.

Nope your wrong. Hint: count the number of letters in each word and decide whether of not a letter should be excluded.

_ i s t i n g _ i s _ e _*_ i _ _ _ e s t i _ _*s a i _*a _ n t*_ e t t _

X,R

distinguished fiddlestick said aunt letty

edit: you posted the phrase above the blanks again but I'm being honest when I say I didn't notice that before I posted. I don't know how I didn't notice but I didn't.

Yep, you got it!

Is there a "D"?
