When a retired businessman is pushed to his death on Manhattan's subway tracks, his daughter retains the services of PI Rachel Alexander in Benjamin's well-plotted, thoughtful ninth episode (after 2005's Without a Word) in her series starring the former dog trainer and her trusty pit bull, Dashiell. The police believe a homeless man killed the victim, Gardner Redstone, so Rachel—escorted by her canine companion—goes undercover as a homeless woman to track down the perpetrator.
