Kurt Wallander was avoiding the training center. It was easy enough, considering the outbreak, but still. He'd scoured back over the surveillance of Cecil, whenever Penny was occupied, looking for any links. Then he found one.

Or, might have found one.

Joan Watson.

He knew the stories, of course. Had met her Sherlock before he'd been let go. The fact that she knew Cecil--

He'd been a peacekeeper too long to believe in circumstance.

So he followed her. He left headquarters just as the screams started, intercepting Joan just as she was slipping into the park. He followed her about twenty feet back, casually, but kept his eyes on her.

He wanted her to know.
