The next morning Maua did not take the car. She walked with Nuru from the school gate at the same hour children usually left on Tuesdays. Daniel stayed across the road because Nuru had said she did not want to feel like she was leading an inspection team. Maua disliked that, but respected it.
"Where does the route begin?"
Nuru pointed to a faded strip of green paint on the curb near the crossing.
"Mama Tesa called them green points. Here you check the traffic, then the kiosk."
The kiosk was a hundred meters away. Its owner, Mr. Mugo, recognized Nuru.
"With your mother today?"
The question embarrassed Maua.
"Does she usually pass here on Tuesdays?"
"Lots of children do. Nuru, Amina, the little one from Block C. Sometimes they buy water."
"And the dog?"
"Kito comes around that time."
"Does he escort them?"
Mugo thought. "He follows movement. When he sees uniforms, he comes from under the lorry. Sometimes children feed him biscuits. I tell them not to."
Nuru added, "Mama Tesa told us not to feed him too."
They continued to the pharmacy. The pharmacist, Lillian, remembered children passing at about 4:12 every Tuesday. She did not hand over camera footage without a formal request, but agreed to record her observation: two to four children often passed; the retired crossing guard used to watch them more closely; later she was not always there.
"Kito?"
"He sits near the gutter. I have never seen him touch a child."
Maua wrote it down without turning it into a certificate of safety. A dog could react differently on another day. The objective was the route, not winning a case for Kito.
The third point was a narrow lane between a bakery and the estate fence.
"Here, if there are too many boda riders, we wait," Nuru said.
"Who taught you that?"
"Mama Tesa."
"And if no adult is around?"
"We wait for older students."
The system was both sensible and fragile. It depended on shopkeepers, older children, a retired guard, and a dog. A web of ordinary kindness had been carrying responsibility that the parents thought existed somewhere official.
Daniel joined them near the estate crossing.
"This is it?" he asked.
"Yes."
"It's short."
Maua looked at him. "Short is not the same as assigned."
At the estate gate, the morning guard, Joseph, confirmed he had seen Nuru arrive many times with other children. Sometimes Kito came behind them; sometimes he did not.
"What happens when they reach the gate?" Maua asked.
"Resident children scan or we recognize them."
"Handoff?"
Joseph shook his head. "The gate is an entry point. We do not take custody."
There was the final flaw. Daniel had treated the estate gate as the place where a child was "received." Security saw it as access control, not custody.
Nuru suggested a test. "You two walk the route without me leading."
Maua and Daniel missed the first turn near a photocopy shop.
"The shortcut is that way," Daniel said.
"Mama Tesa said not to use the shortcut," Nuru replied. "This road has people who can see you."
The longer route passed businesses that could call for help. The shortcut had a high wall and no occupied storefront.
"So safe doesn't mean shortest," Maua said.
"It means somebody can see you."
At the bakery an employee remembered children sheltering there one rainy day. Kito had lain beneath the awning until the group left. He also said the dog crossed the same road alone on many other days.
Daniel put his phone away. "I've been measuring the route in minutes. Nuru measures it in places."
"And we measured custody in calendar blocks," Maua said.
On the way back they saw Kito. He rose from beneath a parked pickup when a group of uniformed children passed. He followed for a while, stopped at the kiosk for water, lost time sniffing a tyre, and then stayed outside the estate instead of entering. When another group of children appeared behind him, he turned and drifted back with them.
Mugo wiped his counter. "If you write your report, don't say the dog guards them like police. But don't say the children were invisible either. The neighborhood saw them. The problem is nobody was officially responsible."
Maua wrote that sentence down.
Kito appeared at three points on the green route. He was part of a pattern, not a guarantee.
And after the last child entered the estate, the dog always went away.
