I stood at the top of the stairs, my mouth opening and closing, completely unable to assemble a single coherent sentence out of the chaos in my head.

So I did the only thing my short-circuited brain could manage.

I stepped silently to one side, and I raised my arm, and I pointed into the guest room, like a grim detective in a film gesturing a suspect toward the body, directing my sweet banana-bread-bearing mother-in-law toward the evidence of her supposed crimes.

If you had frozen the scene right there and shown me a photograph of it, I would not have believed it was real.

A woman at the top of her own stairs, silent, white-faced, arm extended like an avenging figure in a courtroom drama, pointing the way to a bedroom.
