"His breath curdles" is a line in Jenny George's poem Death Of A Child. I can’t imagine anything more horrifying than breath "curdling". The precision of that verb. The breath of a dying child in Jenny George’s hand: "to clot, congeal, change from a liquid into a thickened mass", according to dictionary entries; the vaporous quality of air stiffening, "little by little". Horror, pain and all-encompassing grief lived through and mesmerized into words. DEATH OF A CHILD This is how a child dies: little by little. His breath curdles. His hands soften, apricots heavy on their branches. I can’t explain it. I can’t explain it. On the walk back to the car even the stones in the yards are burning. Far overhead in the dead orchard of space a star explodes and then collapses into a black door. This is the afterlife, but I’m not dead. I’m just here in this field.
