When the Closet Worked Its Magic: a long short story

The closet swallowed his little sister. It really did. And yet, a year later, after it spat her back out, Elmer Warde must lie: I imagined it. I am insane.

This, after people suspected him of kidnapping his own sister.

And after they accused him of trying to murder her.

This is the ironic aftermath of a horror story that gets "solved": the loved ones of the missing person (now missing no more) face a fallout. Elmer's only hope of staying in touch with his little sister seems to be the insanity...
