"Thin Rain, whom are you haunting,
    That you haunt my door?"
--Surely it is not I she's wanting;
    Someone living here before--
"Nobody's in the house but me:
You may come in if you like and see."

Thin as thread, with exquisite fingers,--
    Have you seen her, any of you?--
Grey shawl, and leaning on the wind,
    And the garden showing through?

Glimmering eyes,--and silent, mostly,
    Sort of a whisper, sort of a purr,
Asking something, asking it over,
    If you get a sound from her.--

Ever see her, any of you?--
    Strangest thing I've ever known,--
Every night since I moved in,
    And I came to be alone.

"Thin Rain, hush with your knocking!
    You may not come in!
This is I that you hear rocking;
    Nobody's with me, nor has been!"

Curious, how she tried the window,--
    Odd, the way she tries the door,--
Wonder just what sort of people
    Could have had this house before . . .
