At the VIP clinic, I was helping my nine-month pregnant daughter out of her clothes for her final ultrasound. When her shirt dropped, I stopped breathing.

I typed a single word: READY.

Within four seconds, the three grey dots pulsed on the screen.

Isaac’s reply appeared: AWAITING YOUR COMMAND, ELEANOR.

My thumbs flew across the digital keyboard with practiced, lethal speed: EXECUTE EVERYTHING. ALL FRONTS. NOW.

A brief pause. Then: WITH PLEASURE. SCORCHING THE EARTH.
