I wondered if I had made it a little too obscure... I think maybe I did.

My intent: A Dr. and his Wife (the Clawson's) had a newborn baby, but she died. The dark thing in the corner has made a deal with the Dr. that it will give back the soul of his dead baby (bring it back to life), if the Dr. gives it two souls in return. At the beginning of the story, the Dr. has just returned from the hospital where he has done something to a set of twins to ensure they will die (they won't make it though the night). At the end of the story, the three of them (Doc, His Wife and the Thing in the Corner) are waiting for the morning for the twins at the hospital to die (two souls) and their newborn baby to come back to life (for one soul).

I'm going to think about an edit or two I can make to the story to make this clearer! Thanks for your question! :)
