Warren had called me careful and stubborn in equal measure.

Lorraine knew my cameras worked, and she knew I would not hit an older woman simply because she shouted.

That answer made me furious.

You counted on me to be decent, I said, and then you used it against me.

Lorraine began to cry.

Yes, she said.

That is exactly what I did.

I needed the police to take the whistle and I needed the van to leave before Paul could get it.

Her lawyer asked why she hadn’t simply handed the card to me.

Because the men were watching him too, Lorraine replied.

She took a long breath.

And because if I did nothing, Nathan would sign the building certificate without knowing who was controlling the company that bought it.

I looked at her.

What does one have to do with the other, I asked.

Lorraine reached for a tissue.

Graham Voss used the old emergency dispatch system to hide a route, she said.

Now his company was selling the city a new one that could hide an entire call.

Lorraine’s statement did not answer every question.

It created new ones, which Munroe wrote down carefully as she talked.

She explained that Warren’s original radio could record short bursts of dispatch traffic onto removable media long before the ambulance company adopted digital systems.

He had been worried about a disagreement between the official Bellwood log and what he heard on the air that night.

He copied the traffic because he thought a technician might need to troubleshoot the missing transmission.

Several weeks later, he realized the discrepancy was not a malfunction.

The official log had been corrected to remove a detour requested by Graham Voss.

Warren told his supervisor, who advised him to stop looking into the matter.

Lorraine said Warren became ashamed and withdrew from volunteer work.

When he became ill years later, he asked her to make sure Isabel heard the original recording.

But he also confessed he had kept one important fact from her.

The person in the second ambulance had not been Luis Moreno.

Luis was the witness who saw someone else being moved.

The second patient was a maintenance supervisor from the apartment complex, a man named Daniel Strake.

I had heard that name before.

He appeared in the building owners’ civil settlement as an employee who died in the fire.

Lorraine said the family believed Strake had been inside the burning building when it collapsed.
