I didn’t forgive her.

My cheek still hurt, and I had spent the entire day answering questions about being attacked outside my own home.

But for the first time, I considered that she might have been trying to protect someone other than herself.

Maren’s phone vibrated.

She looked at the screen and went very still.

A text from Isabel’s number had just arrived.

It contained only six words.

Tell Nathan the whistle was Warren’s.

Munroe read Isabel’s message without touching Maren’s phone.

He asked her to leave the screen open while an evidence technician photographed it.

Then he asked a question neither of us expected.

Did Warren Kessler make his own whistles?

I remembered a pegboard in his garage crowded with parts for radios, fishing reels, and old clocks.

I remembered the little brass whistles he made for children who took the neighborhood bicycle safety course.

Each had a removable cap so the owner could clean the chamber.

I told Munroe that Lorraine’s whistle looked like one of those handmade devices.

He asked Officer Ortiz to check whether it had been inventoried with her possessions.

When the answer came back, he stood up so quickly his chair scraped the floor.

Lorraine had surrendered her keys, wallet, and coat when she was booked.

The whistle was still in the coat pocket.

It had not been examined because nobody thought an ordinary whistle mattered.

The evidence technician returned twenty minutes later carrying a sealed bag.

Through the plastic I could see the silver whistle I had watched Lorraine blow beside my mailbox.

The technician photographed the cap and began documenting the inspection.

He unscrewed one end with a padded tool.

A tiny folded square of paper slid into a tray.

Inside it was a memory card.

Munroe did not smile.

He wrote down the time and told the technician to preserve the device for forensic examination.

I found myself staring at the whistle as though it had spoken.

Lorraine had been holding a recording in her hand while she struck me.

She had needed officers to take that object away from the men watching her.

The assault made no sense until I remembered that booking meant personal belongings would be inventoried.

If she surrendered voluntarily, Paul could accuse her of stealing company equipment and force a different kind of encounter.

If she walked to my porch and asked for help, the men in the van could intercept her before she made it across the street.
