In Over Your Head

An investigative journalism student is found dead on the beach. The cause of death is determined as a drowning, but her lungs contain freshwater and not the ocean's saltwater. The student had been investigating a drug ring at her university. Jane must grudgingly work with a former colleague, who is now a new drug-unit lieutenant, in order to solve the case. Elsewhere, Maura learns that her mother Hope received a sizable donation to open her charity clinic. The donor was Paddy Doyle. He is asked to give his statement about how he got the money, so the FBI will leave Hope alone, but he refuses.
