Something moved on the grounds down beneath my window — cast a long spider of shadow out across the grass as it ran out of sight behind a hedge. When it ran back to where I could get a better look, I saw it was a dog, a young, gangly mongrel slipped off from home to find out about things went on after dark. He was sniffing digger squirrel holes, not with a notion to go digging after one but just to get an idea what they were up to at this hour. He’d run his muzzle down a hole, butt up in the air and tail going, then dash off to another. The moon glistened around him on the wet grass, and when he ran he left tracks like dabs of dark paint spattered across the blue shine of the lawn. Galloping from one particularly interesting hole to the next, he became so took with what was coming off — the moon up there, the night, the breeze full of smells so wild makes a young dog drunk — that he had to lie down on his back and roll. He twisted and thrashed around like a fish, back bowed and belly up, and when he got to his feet and shook himself a spray came off him in the moon like silver scales.
