21. The Code

When Schanke's ex-partner Delehanty shows up, his rich, comfortable, and "warm" life in Arizona, gets to Schanke's winter-worn heart. When Schanke and Delehanty conclude that a series of deaths are the result of product tampering, Nick's hunch about the case drives a wedge between him and Schanke. When Schanke refuses to listen to Nick, he must solve the case despite Schanke and Delehanty's conclusions, and before Schanke decides Arizona might be the place to be.
