They visited the third affected property together.
It belonged to the Parkers, a family with two children and a washing machine that had stopped filling properly.
Mason Parker greeted them beside a mountain of towels waiting for a trip to the laundromat.
His wife, Imani, had missed a shift at the library when the first pressure failure flooded their utility closet.
“The pilot people said our pipes were the problem,” Mason said.
“They offered a discounted replacement if we paid before Friday.”
He showed Rachel a text from a company called ClearMeasure Civic Systems.
The offer was not from the city.
Its amount had been large enough to make Mason consider a loan.
Rachel asked whether anyone had installed anything.
“A worker checked the outside line while I was at work,” Mason said.
“Carol was supervising.”
He said the word supervising with a doubtful expression.
“She told me she was the block coordinator.”
June made a disgusted sound.
“Nobody elected her to coordinate my sink.”
Rachel called Owen and repeated what the neighbors had told her.
He thanked her and asked everyone to keep the flyers, messages, and invoices without confronting the worker.
“We need to determine whether these are unauthorized devices,
installation errors, or something else,” he said.
“Don’t let anybody open a service line again until the utility approves the work.”
Rachel thought he sounded more worried than he had earlier.
“Do you suspect contamination?”
“I don’t have evidence of that,” Owen answered.
“The pressure changes and unauthorized access are enough reason to treat this seriously.”
Rachel looked at the Parker children working on homework at the kitchen table.
They had adapted to washing dishes by hand and carrying laundry across town because strangers had apparently turned their water supply into an experiment.
Nothing about that felt small.
CHAPTER THREE — THE BLUE DROP
The following morning, a woman named Lena Ortiz arrived at Rachel’s door carrying a notebook and a faded municipal identification badge.
She introduced herself as the city’s program compliance officer.
“I am not part of ClearMeasure,” she said immediately.
“I need to make that clear before anything else.”
Rachel invited her onto the porch but kept the door closed behind her.
Lena asked whether the worker who had visited Rachel had mentioned a control group.
“No,” Rachel said.
“He asked to check my meter.”
Lena wrote it down.
She explained that the city had accepted an application from ClearMeasure to run a limited demonstration of water-use reporting.
The project was supposed to involve simulated data inside an equipment workshop, not physical devices placed in occupied homes.
The application’s budget was modest and covered staff training, printed materials, and a final report.
It did not authorize installation in water lines.
“Someone expanded the experiment without approval,” Rachel said.
“That’s our concern,” Lena answered.
“The city never agreed to let them reduce anyone’s pressure.”
Rachel took the flyer June had given her from a folder.
Lena examined the logo.
“They used our program colors,” she said.
“That makes the flyer look like an official city notice, but it isn’t one.
”
“Carol handed these out.”
“We’re interviewing her too,” Lena said.
Rachel asked if she could attend those interviews.
Lena shook her head.
“You can give a statement, but I cannot disclose another person’s interview.”
It was frustrating and correct at the same time.
Rachel had to accept both facts.
Before leaving, Lena asked an unexpected question.
“Did Carol ever ask whether you could hear water moving through the walls at night?”
Rachel remembered a conversation at the fence in early spring.
Carol had asked whether the pipes clicked after midnight.
Rachel had thought she was making ordinary neighborly talk.
“Yes,
” she said.
“Why?”
Lena hesitated.
“ClearMeasure’s proposal described a method for identifying waste by listening to changing water pressure.”
“But my pipes weren’t making that noise until recently.”
“That is one of the discrepancies we’re investigating.”
