"'The door of the garden where I live. That is what it opens. Wait for
the first moonlight night and you will see,' said the dove, and then it
flew off, higher and higher up into the sky, already growing dusk and
gray, for the winter was not far off.

"Letty looked again at her precious key. Then very carefully she folded
up the ribbon with the key in the centre of it and hid it in the front
of her dress, and feeling as if she were in a dream, she made her way
home.

"For some days nothing more happened. But Letty waited patiently till
the time should come which the bird had spoken of. And the looking
forward to this made the days pass quickly and less dully, and often and
often she said over to herself, 'if you are good and gentle and do your
work well,' and never had she tried more to be good and helpful, so that
one day her mother said, 'Why, Letty dear, you're getting as quick and
clever as Hester.' Hester was the big sister--and Letty said to herself
that the dove had made her happier already, and that night when she went
to sleep she had a sort of bright feeling that she never remembered to
have had before.

"'I think it must be going to be moonlight,' she thought to herself. But
when she looked out of the window the dull little street was all wet,
she could see the puddles glistening in the light of the lamps--it was
raining hard.

"Letty gave a little sigh and went to bed. She had a little bed to
herself, though there were two others in the room, for her elder sister
and two of the younger ones.

"In the middle of the night Letty awoke--the rain was over evidently,
for the room was filled with moonlight. Letty started up eagerly, and
the first thing that caught her sight was a door at the foot of her bed,
a common cupboard door, it seemed, with a keyhole in it. It was the
keyhole I think which first caught her attention, and yet surely the
door had always been there before?--at least--at least she thought it
had. It was very queer that she could not quite remember. But she jumped
out of bed--softly, not to wake her sisters, and though half laughing at
her own silliness in imagining her tiny silver key could fit so large a
lock, she yet could not help trying it. She had the key and the ribbon
always with her, carefully wrapped up, and now she drew out the key and
slipped it in, and, wonderful to tell, it fitted as if made for the
lock. Letty, holding her breath with eagerness, turned it gently--the
door yie
