Classic Poem

A soft black shimmering gown
Crept sinuously
Into the lamp-lit library.
I could see her eyes
Glitter
Goblin-green, devil-red,
Weird, witching sparks,
That terrified.
She pounced
Upon a little mouse-gray book,
And as she undulated
Cautiously
Out of the room,
I could almost hear
The swish
Of an invisible tail!
