Simon Says... Swim

Detective Kate Morgan is stumped, trying to decide when a case is really a case and when it belongs on her desk or someone else’s. She’s homicide and this? … This is something else, right? Following up the leads doesn’t help, only confuses the issue—until someone slips up or slips away literally.

As usual, he has few answers, and the ones he does find make no sense.

As Kate works her way through the details of multiple cases—or not cases—the realization is worse than anyone had realized.
