The priest dips the ring in holy water, murmuring a blessing, and then the groom takes it. In nomine Patris, he says, in a clear voice, audible to all, even those at the back, sliding the ring on to her thumb and then off again, in nomine Filii, the ring is pushed on to her first finger, in nomine Spiritus Sancti, her middle finger. At Amen, the ring encircles her third finger where, the groom told her the other day, as they were hiding in the orchard, runs a vein that travels straight to her heart. It feels cold, for a moment, against her skin, and damp with holy water, but then the blood, flowing straight from her heart, warms it, brings it up to the temperature of her body.
