After my husband died, a nurse accidentally let it slip that a woman had been visiting him for several weeks before his death 

The letter began simply.

My darling Emma,

If you’re reading this, then I’m gone.

I pressed one hand over my mouth.

Jack had always written my name that way—slightly tilted, the E larger than it needed to be. I had seen his handwriting on birthday cards, grocery lists, little notes he’d slipped into my lunch when we were teenagers.

But never like this.

Never from the grave.

The woman stood silently on my porch while I read.
