The Raven King is a character (sort of...) in the aforementioned Jonathan Strange. 
I remember reading The Owl and the Pussycat in my fourth grade literature book, and liking it very much, but I should read it again. I keep getting it mixed up with The Walrus and the Carpenter, which is even better 
Random poem from English text:
At the Theatre: To the Lady Behind Me
Dear Madam, you have seen this play;
I never saw it till today.
You know the details of the plot,
But, let me tell you, I do not.
The author seeks to keep from me
The murderer's identity,
And you are not a friend of his
If you keep shouting who it is.
The actors in their funny way
Have several funny things to say,
But they do not amuse me more
If you have said them just before;
The merit of the drama lies,
I understand, in some surprise;
But the surprise must now be small
Since you have just foretold it all.
The lady you have brought with you
Is, I infer, a half-wit too,
But I can understand the piece
Without assistance from your niece.
In short, foul woman, it would suit
Me just as well if you were mute;
In fact, to make my meaning plain,
I trust you will not speak again.
And---may I add one human touch?---
Don't breathe upon my neck so much.
