S1·E14 Killing Me Softly

On the trail of known arsonist and murderer Anthony Rossi, Danny and Barbara stage a divorce-without confirming for the kids that it's all for show. The plan: to catch Rossi in the act of offering his known hitman services to Danny. The murder-for-hire offer comes as anticipated, but Danny is unsuccessful at getting the offer on tape. Now the only way to get a conviction that will stick is to catch Rossi in the act of killing Barbara. The danger becomes worse when Rossi insists on including an unpredictable, trigger-happy partner in the plan, a partner who soon begins to suspect a set up and winds up being a threat to the entire Arno family.
