The bucket is industrial grade. He found it in the utility room, already there, which told him something about the kind of man who lived in this apartment.
He works from east to west. Floor first, then surfaces, then the door handle. The gloves are surgical — not the thick yellow kind, but the thin powder-free kind he uses in the OR. He goes through a box a week, most of them at the hospital. Nobody counts.
He hums something. An old song. His mother used to sing it in the kitchen when she thought no one was listening. He has never been able to remember the title. Just the melody, rising and falling in the back of his skull like a tide that does not know how to stop.
It is two in the morning. Outside the window, Philadelphia glitters in the rain — amber and cold blue and dirty white. From up here on the fourth floor, it looks almost kind.
He checks his watch. Forty minutes before he needs to leave. Forty is comfortable. He will be done in twenty-five.
The apartment belongs to a man named Derek Rowe. Thirty-eight years old. Supply chain coordinator. That is what his tax returns say. What they do not say is that the supply chain ran fentanyl and methamphetamine from a processing house in Kensington through a network of distributors who worked schools and community centers and the margins of churches where people were still trying to be good.
Fourteen people died in the last eighteen months from product traced to Rowe's network. Two of them were seventeen. One of them was thirteen.
Derek Rowe is no longer a problem.
He died of a cardiac event, as far as any medical examiner will ever determine. The compound Gideon used — synthesized from a base ingredient available in any surgical supply catalog, if you knew what to order and why — is undetectable in standard autopsy panels. It is, in a clinical sense, elegant.
Gideon moves to the surface near the window. His reflection catches in the glass for a moment — tall, lean, a man whose face has been described by women as handsome and by men as difficult to read. He looks at himself without particular interest and goes back to work.
There is a photograph on the shelf near the television. Derek Rowe and two children, a boy and a girl, grinning at something outside the frame. Gideon does not touch it. He works around it with careful geometry, and when he is finished he stands for a moment looking at it.
He thinks: every man has someone who loves him.
Then he thinks: the children of the girl who died at thirteen also loved someone.
He picks up the bucket. The gloves go into a separate bag he carried up inside his jacket. Both will disappear into dumpsters on opposite ends of the city — not near each other, not near here.
He lets himself out. The hallway is empty. He takes the stairs.
At the bottom, he pushes through the fire exit into the rain. It falls cold and steady, the way Philadelphia rain always does — without ceremony, without apology. He turns up his collar and walks to where he parked, two blocks away, facing west.
He drives eight minutes before he feels his shoulders drop.
The city moves past outside the window, wet and alive, full of people who are going to wake up tomorrow and not know that something has been removed from among them. Something that was spreading.
That is how he thinks about it. Not as murder. As excision.
He turns onto Girard Avenue and follows it north toward home — toward the apartment that holds a bottle of bourbon and a laptop with a list and four names that do not yet have lines through them.
Whether what he was doing was necessary, or inevitable, or something that had started as one thing and quietly become another — that was a question he had stopped asking somewhere around the third name, eighteen months ago.
He does not ask it now.
He just drives
