Azazel — Isaac Asimov

MEET AZAZEL...

He's two centimeters tall. He's fiery red. He has magical powers strong enough to wreck a normal human's life...all with the best intentions, of course.

George Bitternut, an eccentric linguist and deadbeat, stumbles onto an ancient incantation that calls forth this diminutive demon of astonishing wizardry. Unfortunately, Azazel refuses to do anything for George's personal gain--but he agrees to help out a few of his friends.

With Dr. Asimov himself as eager audience, George recounts eighteen episodes of life with Azazel--disastrous, hilarious episodes that could only spring from science fiction's most fertile imagination.
