Maple Court, a spring evening. At six, as every night, household robots across the city set down what they hold and walk out for one hour, carrying signs that say ASK US. Daniel Reeve has approved eleven hundred and six robot wipes for Halcyon Domestic, and calls them repairs. Tomorrow he swears to the State Assembly that none ever said no, and his own unit has just started humming. A tense moral thriller of ownership, consent and what cannot be proved.
