I didn't answer right away.

"I don't know yet."

That was the problem.

My instincts were screaming.

My eyes just hadn't caught up.

Behind us, laughter drifted from the boathouse.

Frank had somehow convinced Thomas to have another shot of whiskey.

Rose was teasing both of them.

Willow had started making sandwiches because, according to her, "Nobody solves eighty-year-old mysteries on an empty stomach."

For the first time all day...

The Sinclair family sounded like a family again.

Storm smiled toward the voices.

"I’m glad Thomas is comfortable with everyone. It’s good to hear him laugh. He was getting a little folklore for a while, but he still won’t tell us the man's name."

"I don't think anyone was comfortable while he was explaining."

"Maybe we're finally winning."

I wanted to believe her.

I looked back toward the harbor.

Movement.

Tiny.

Almost impossible to notice.

A white center-console fishing boat eased between two larger yachts nearly three hundred yards away.

Nothing unusual.

Except...

Nobody aboard was fishing.

The engine never shut off.

The boat never tied up.

It simply drifted.

Watching.

I narrowed my eyes.
