"Marianne?" I said. "Have you chased out the sparrow? Good. Then you can help me with the other one."
We opened front doors and back, and when the sparrow was (to Miss Hope's great discontent) gone, we went through the house, trying to figure out how they'd gotten in.
Not a door or window was open. There was, I'd swear, no way the birds could have gotten in the house?
So . . . did these sparrows fall sideways in time from a parallel dimension? Or forward in time from a half century ago? Or did they teleport? Or (reality being stranger than we can imagine) did some distant Power create or project them into our house? Is it possible that we're lucky it was sparrows rather than mastodons or Vikings?
I'll never know.
