The Switch — Summary

The Muirs are cold on purpose, and they know where the heat is. Their house in the Borders is two houses in one: the front the provision built, and the back they built inside it, with a wood stove, a pump in the yard, a pencil rota, and a rule that nothing there is done by anything but a person. Mirren and Callum made the rule nine years ago. The door between the houses is ordinary and has never been locked. That is the point and the problem.

The work is real. Iona, fourteen, has carried water in January with cracked hands. Callum comes in at dusk with his back gone and has been needed at a particular spot at a particular hour, and the front house would have done it and has never been asked. Manufactured weight presses like any other until the carrier remembers who built the press, and the builder cannot forget. The hardship is honest and the necessity is not.

Mirren’s account is that the children are the point: a child who has carried water knows something, and the children could not walk through the door. That is true, and it is the problem. The parents installed the weight and can uninstall it; the children were born under it, and to them it is the world until the day it is a door. Iona has recently noticed the door, and asked her mother to say out loud that they were choosing and she was not.

Whether manufactured weight is the only kind honest about itself, or hollowed by that honesty, is left open. It works as long as nobody checks the hinge. Iona has started checking, and nothing in the arrangement accounts for her.
