Dipping into the reader mailbag, Lynne asks: “What will Martha be up to in Season 4? Will her acting school open?” Your answer, from show boss Andrew W. Marlowe himself: “We have a fun episode where Martha and Castle end up on the wrong side of a bank robbery while she’s trying to get a new loan for her school.” (P.S. In a fun wink-wink to TV fans, the robbers nickname themselves Dr. Quinn, Dr. Huxtable, Dr. Howser and Trapper John, TVLine has learned.) Meanwhile, who’s working hard on the outside to hopefully save the day? Why, Beckett of course.
