Lemur
S3, E4: Cardinal and Delorme get a sketch of the Island Road killer from Sam, and with the department stretched thin, Commanda volunteers to keep her and her mother safe. Cardinal and Delorme find evidence leading them to known gun dealer Misha Pulaski - last seen meeting with the Barstows at a local watering hole. He has an alibi, but admits he was buying guns from them – guns he has yet to receive. Unable to let go of tracing the anonymous cards, Cardinal makes a big connection when he traces a printer flaw to Roger Felt, a man he once put away for fraud. Cardinal hauls him in, enraged. Meanwhile, Delorme stakes out an ATM just as the robber strikes. Before she can catch the perpetrator, shots are fired and she finds the mugger dead. Delorme returns to the station and walks in on chaos as Cardinal bullies a confession from Roger Felt for writing the cards – but not for killing Catherine. Dyson grills Delorme, wondering if Cardinal is fit for duty.
