The decision has a timestamp: 9:47 AM.
Not because he set an alarm or made a deliberate mark, but because he's been logging times out of habit now—the call at 4:12, the translation service activity flagged at 11:30, the name reference surfacing at 2:18 in the recording. Time is data. He checks it when his thinking shifts direction. 9:47, Friday morning, and he's going to Daly City.
He opens the Evidence Summary. Reviews the confidence assessment—84%—and closes it. The document is thorough. What it doesn't contain is visual confirmation: what the behavioral patterns look like in physical space, the subject present and observable rather than reconstructed from recordings and transaction records. He is a project manager by training. He knows the difference between documented evidence and observed behavior. He puts on his jacket. Phone in the right pocket. Keys in the left.
The route to Daly City takes twenty-two minutes on a Friday morning when 280 isn't backed up past the Alemany ramp, and it isn't backed up this morning. He drives without music or Cascade running—just the freeway sound and the flat November light at the low angle that means high clouds, no color. He learned to drive on these freeways. He knows the exit, the turn onto Junipero Serra, the residential streets from the boulevard down to the Westlake neighborhood. The fog sits lower here than anywhere in the city. He opens the window at a light and the damp smell of it comes through, and it is a smell from thirty years of arriving at this house.
He parks on Mirabel Avenue, two blocks north of the house, facing south so he can see the front door in his rearview. Engine off. 10:09 AM. He waits.
She emerges at 10:24. The subject exits the front door carrying a padded envelope. Keys in her left hand, envelope in her right. She doesn't check the street. She turns left toward the sidewalk.
Marcus is out of the car in seven seconds. He crosses to the far side of the street and keeps forty feet between them. A curtain shifts in the front window of the house directly opposite—just the fabric settling, probably, or someone behind it. He slows. Reaches for his phone as though checking a message. The curtain doesn't move again.
The subject walks with the same pace she's always walked—right shoulder a half-degree lower than the left, heels touching down firm. Not hurrying. Thinking. He's been seeing this gait for thirty-four years. He knows its variations: the slower version carrying groceries, the quicker one when she's running late. A dog tracks her from behind a chain-link gate, barking twice, then giving up. He notes the time. He keeps forty feet.
She turns up the path to Mrs. Fong's house without slowing. Three doors from her own. He has walked this block as a child, was brought here for dinners that ran four hours, left with containers of food stacked in a bag he held with both hands. He knows which step on the front porch has the soft board.
He positions himself at the corner of the neighboring property's fence line. The subject rings the bell. Waits. The door opens—a greeting exchanged in Cantonese he can't hear—and the door closes behind her. 10:27 AM.
He's known about the alley since he was twelve and used it to retrieve a ball that went over a neighbor's back fence. He takes it now, walking north on Mirabel and cutting east on the first cross-street, and finds the rear of Mrs. Fong's property without checking an address. The kitchen window faces the back garden. Same layout as the subject's house—same floor plan, same decade, same contractor's work replicated across four blocks. Through the glass: the kitchen table, two chairs, the overhead light on against the cloud-gray morning. He stays close to the fence.
He has sat at that table. Eight years old, legs not reaching the floor, Mrs. Fong pushing a plate of pineapple buns across the laminate toward him while his mother and her friend talked in Cantonese above his head about things he couldn't follow and didn't need to. The light fixture might be the same one.
At 10:31, both subjects are seated. Tea on the table. The secondary individual has her phone screen angled toward the primary subject, who leans forward to look at it. He cannot hear through the glass, but the posture tells him—this is not casual glancing, this is someone reviewing specific content. The secondary individual says something. The primary subject covers her mouth and laughs. Her shoulders lift. She's looking at something on the screen that produces laughter that's private, that belongs to a reference he isn't part of.
He takes the first photograph at 10:32. Shutter sound muted—verified before leaving the apartment. He adjusts position for a better angle on the phone screen, but the content isn't legible from the distance.
The secondary individual sets the phone face-down on the table. Both women lean toward each other in close conversation. The subject produces the padded envelope and slides it across the table. The secondary individual takes it, doesn't open it, sets it against the wall behind her.
A third cup is brought to the table. At 10:47, the phone is picked up again and both women are looking at it, and there is a moment where the primary subject puts her hand over the secondary individual's hand. They are looking at something he can't see, both nodding, their faces carrying an expression he cannot categorize from outside a window through glass.
He photographs the gesture. His thumb finds the capture button and the screen registers the image: two women at a kitchen table, one hand covering the other, both looking down at something small enough to hold. Their faces in an expression his evidence file has no field for. He lowers the phone. Raises it. The gesture is still happening—his mother's hand on Helen Fong's hand, the same hands that pushed pineapple buns across this table when he was small enough that the world was a place where two women drinking tea meant two women drinking tea. His chest tightens. He photographs through it. He does not note the hesitation in the log. He does not have language for it from the evidence file. Observed duration at departure: 22 minutes. He walks back to the car.
He transmits the photographs to Cascade from the parking spot on Mirabel: time, duration, observed behaviors, envelope transfer, mobile device examination.

Eighty-nine percent. Five points up from 84%, the highest yet. The physical surveillance confirmed what the records predicted—in-person meeting, correspondence transfer, shared review of contact material. He gathered data, Cascade processed it, the confidence moved. The feedback loop doing what feedback loops do.
He types Yes. Add to Evidence Summary under Physical Surveillance and looks at the dashboard. The Westlake neighborhood in its November light: flat, damp, the row houses in their identical setbacks. He starts the engine.
He takes Junipero Serra south to Brotherhood Way. At the junction, the Ranch 99 where the subject shops on Thursdays is set back from the intersection behind its parking lot. She came back from that store once with lotus root when he was twenty-eight and his father had been dead for two years and she made soup without being asked and didn't mention why. He remembers the soup. He remembers not asking why. He passes the store. 11:09 AM.
Back in his apartment by 11:38. He opens the Evidence Summary and reviews the section Cascade populated: Physical Surveillance — 2024-11-22. Accurate against his notes. He adds the envelope exchange under correspondence routing. The transfer log has a new entry Cascade flagged overnight—a fourth deposit, same routing pattern as the previous three. He cross-references it with today's observation and updates the aggregate. He saves the document.
The cursor blinks after the final entry: Confidence: 89% (updated 2024-11-22, physical surveillance confirmation). He reads the complete evidence section above it—the timeline, the behavioral analysis, the Key Individuals entries with their functions documented, the financial activity totaled, the communication patterns organized into their channels. Everything current. Everything verifiable. The document is the most organized and comprehensive professional work he has produced in the eleven months since the layoff. Janet would have recognized the impulse—how attention narrows, how everything else falls away. She'd had a word for it during the marriage. He doesn't remember the word. He remembers the look on her face when she said it.
The document concerns a man named Bobby who receives money from the subject's retirement account and correspondence routed through a woman three doors down who has called him ah-jai since he was twelve.
The subject has not been referred to by her first name or by any familial designation since Mirabel Avenue. This is correct practice. You refer to individuals by their function, not by your relationship to them. The relationship introduces bias. Bias is what missed things with Janet. This time he is not going to miss anything. He closes the laptop.
He doesn't notice that he's stopped noticing.
