It was a collection of people waiting for somebody to make those rules work.

Chapter Six: The Other Side of the Wall

At 5:14, Frank found the second problem.

He did not find it on a computer. He found it the way he had found most things in thirty-six years of public works: by remembering a sound that was not supposed to be there.

“Hear that?” he asked Lena.

They were standing beneath an awning behind Gate Seven. Rain dripped from the gutters onto an exposed concrete channel. A constant low rumble came from the water rushing beyond the station.

“The river?” Lena asked.

“Underneath it.”

She listened.

There was a hollow rushing sound from a pipe that should have carried water only in the other direction.

Frank crouched at the edge of a safe viewing platform. “They put a temporary discharge in when Harbor Point was under construction. It was supposed to carry runoff into the old industrial retention area. But when they built the decorative flood berm, that outlet disappeared.”

“Where does it discharge now?”

He shook his head.

Lena looked at the as-built drawing taped above the station’s desk. There was a neat blue line leading toward the abandoned industrial basin. It ended beside a label reading *FUTURE CONNECTION.*

A future connection was not a connection.

“Get me the revised drawings,” Lena said.

“Grayline keeps those on their server.”

“Get me whatever your crew photographed during construction. Anything.”

Frank pulled out his phone and started scrolling through a folder of worksite photographs. Most were unremarkable: excavators, muddy trenches, concrete forms, workers posing beside new equipment. Then he stopped.

“Here. The culvert before they covered it.”

Lena enlarged the photograph. She recognized the orientation from the old rail tracks in the background. The temporary drainage line did not lead to the industrial basin anymore. It turned south, into the lower end of the municipal channel.

Toward Willow Court.

The floodgate was not the only way river water could reach the neighborhood. Even with Gate Seven functioning properly, Harbor Point’s drainage system could funnel a dangerous volume of stormwater toward the very district the redevelopment was supposed to help protect.
