The no-heat call come in on the coldest morning of the year, the kind where the trucks don't want to turn over and a man learns to sit a minute and let the diesel come up before he asks anything of it. A rambler out on Frost Road, an older fella named Ostrander on the line saying the furnace ran all night and the house never got past fifty, and he'd had two other outfits ahead of this one and both had scratched their heads and charged the trip fee and gone.
Dell had been in ductwork better than twenty years, since back when you still saw octopus gravity furnaces in the old farmhouses out that way, and there wasn't a whole lot left that surprised him, or that's what he'd have told you climbing down out of the truck with his light and his manometer and the cold coming straight through the coveralls like they weren't there. The Carrier in the hall closet was fine. Fired clean, pulled its gas, blower moving air the way a blower's supposed to. Warm at the plenum. Warm a foot down the trunk line. And then nothing coming out the registers but a thin cold breath, like the house itself was doing the breathing and had been for a while.
So it was under the house, which is where it near always is, and Dell pried up the crawlspace hatch in the mud room and put the light down into the dark and stopped there on his knees a second.
It was warm down there. Not crawlspace warm, not that dead even cool of dirt that never once in its life sees the sun. Warm like a room a person keeps.
He went down anyway, because that is the job, elbows in the poly and the smell of it coming up at him, and the first thing the light found was the ductwork. The trunk line come off the plenum and run maybe four feet and then it just quit, cut clean with tin snips and the take-offs to the registers capped over with duct board and foil tape, neat, neater than most paying jobs Dell had seen, and the whole output of that furnace turned and dumped straight out into the crawlspace under a man's feet. Whoever done it knew air. Knew it better than the two outfits that come before and stood in the hall and shrugged.
The nest was back in the far corner, up on pallets to keep it off the ground. A camp mattress and a sleeping bag and two moving blankets, a Coleman lantern, a five-gallon bucket he did not shine the light down into. A little stack of paperbacks gone soft with the damp. Beer cans lined up along a floor joist the way a man lines them up when he has got the time to be tidy about it, and an Old Crow bottle stood empty at the head of the bed like it was keeping watch. Dell counted the cans without meaning to. He got to somewhere past thirty and quit counting.
He backed out of there faster than a man his age has any business moving through a crawlspace and come up into the mud room and Ostrander was standing in the kitchen doorway with the three dogs around his legs, two shepherds and some brown thing, all of them looking at Dell mild and friendly, tails going a little.
"Well," Ostrander said. "Is it the blower? The last fella said it might be the blower."
Dell told him to get his coat on and go sit in the truck where it was warm, and to bring the dogs, and Ostrander did it the way an old man does when a younger one uses that voice, without much fuss, only stopping to get the leashes off the peg by the door. Dell called the county from the cab. He gave the address twice because his voice wanted to do something on the first pass that he did not care for.
They figured after that the man had been down there the better part of the winter, going by the cans and the way the paperbacks had swelled. Come and gone through the old coal chute on the north side, the one painted shut so long ago Ostrander had forgot it was ever a door. Whoever he was, he was gone before the deputies come, and they never did put a name to him.
What Dell kept coming back to, the part he'd tell and then go quiet after, was the dogs. Three dogs in that house all winter long, and a stranger sleeping under their floor every night of it, close enough they'd have heard him turn over. And not one of them, not the whole time, had ever once barked.
