“Beats me. I heard it just now as I was going out the gate.”

We stood there, our ears attuned to the usual sounds of morning in the neighborhood. For one full minute, there was nothing, and then it started up again. I tilted my head like a pup, pricking my ears as I tried to pinpoint the origin, which I knew was close by.

“Gus?” I asked.

“Possibly. Hang on a sec. I have a key to his place.”

While Henry returned to the kitchen in search of the key, I covered the few steps between his property and the house next door, where Gus Vronsky lived. Like Henry, Gus was in his late eighties, but where Henry was sharp, Gus was abrasive. He enjoyed a well-earned reputation as the neighborhood crank, the kind of guy who called the police if he thought your TV was too loud or your grass was too long. He called Animal Control to report barking dogs, stray dogs, and dogs that went doo-doo in his yard. He called the City to make sure permits had been issued for minor construction projects: fences, patios, replacement windows, roof repairs. He suspected most things you did were illegal and he was there to set you straight. I’m not sure he cared about the rules and regulations as much as he liked kicking up a fuss. And if, in the process, he could set you against your neighbor, all the better for him. His enthusiasm for causing trouble was probably what had kept him alive for so long. I’d never had a run-in with him myself, but I’d heard plenty. Henry tolerated the man even though he’d been subjected to annoying phone calls on more than one occasion.

In the seven years I’d lived next door to Gus, I’d watched age bend him almost to the breaking point. He’d been tall once upon a time, but now he was round-shouldered and sunken-chested, his back forming a C as though an unseen chain bound his neck to a ball that he dragged between his legs. All this flashed through my mind in the time it took Henry to return with a set of house keys in hand.

Together we crossed Gus’s lawn and climbed the steps to his porch. Henry rapped on the glass pane in the front door. “Gus? Are you okay?”

This time the moaning was distinct. Henry unlocked the door and we went into the house. The last time I’d seen Gus, probably three weeks before, he was standing in his yard, berating two nine-year-old boys for practicing their ollies in the street outside his house. True, the skateboards were noisy, but I thought their patience and dexterity were remarkable. I also thought their energies were better spent mastering kick-flips than soaping windows or knocking over trash cans, which is how boys had entertained themselves in my day.

I caught sight of Gus a half second after Henry did. The old man had fallen. He lay on his right side, his face a pasty white. He’d dislocated his shoulder, and the ball of his humerus bulged from the socket. Beneath his sleeveless undershirt, his clavicle protruded like a budding wing. Gus’s arms were spindly and his skin was so close to translucent I could see the veins branching up along his shoulder blades. Dark blue bruises suggested ligament or tendon damage that would doubtless take a long time to mend.

I felt a hot rush of pain as though the injury were mine. On three occasions, I’ve shot someone dead, but that was purely self-defense and had nothing to do with my squeamishness about the stub ends of bones and other visible forms of suffering. Henry knelt beside Gus and tried to help him to his feet, but his cry was so sharp, he abandoned the idea. I noticed that one of Gus’s hearing aids had come loose and was lying on the floor just out of his reach.

I spotted an old-fashioned black rotary phone on a table at one end of the couch. I dialed 9-1-1 and sat down, hoping the sudden white ringing in my head would subside. When the dispatcher picked up, I detailed the problem and asked for an ambulance. I gave her the address and as soon as I hung up, I crossed the room to Henry’s side. “She’s saying seven to ten minutes. Is there anything we can do for him in the meantime?”

“See if you can find a blanket so we can keep him warm.” Henry studied my face. “How are you doing? You don’t look so good yourself.”

“I’m fine. Don’t worry about it. I’ll be right back.”

The layout of Gus’s house was a duplicate of Henry’s, so it didn’t take me long to find the bedroom. The place was a mess-bed unmade, clothes strewn everywhere. An antique chest of drawers and a tallboy were cluttered with junk. The room smelled of mildew and bulging trash bags. I loosened the bedspread from a knot of sheets and returned to the living room.

Henry covered Gus with care, trying not to disturb his injuries. “When did you fall?”

Gus flicked a pain-filled look at Henry. His eyes were blue, the lower lids as droopy as a bloodhound’s. “Last night. I fell asleep on the couch. Midnight, I got up to turn off the television and took a tumble. I don’t remember what caused me to fall. One second I was up, the next I was down.” His voice was raspy and weak. While Henry talked to him, I went into the kitchen and filled a glass with water from the tap. I made a point of blanking out my view of the room, which was worse than the other rooms I’d seen. How could someone live in such filth? I did a quick search through the kitchen drawers, but there wasn’t a clean towel or dishrag to be found. Before I returned to the living room, I opened the back door and left it ajar, hoping the fresh air would dispel the sour smell that hung over everything. I handed the water glass to Henry and watched while he pulled a fresh handkerchief from his pocket. He saturated the linen with water and dabbed it on Gus’s dry lips.
