Mr. Monk Is on the Air

S5, E13: Popular shock jock Max Hudson is doing his morning radio show when he gets a phone call. Across town at Max's house, his wife, Jeanette, has been found dead. In an apparent accident, Jeanette left the gas from her bedroom fireplace on, took a nap, and died of asphyxiation. Jeanette's sister, Linda, goes to Monk for help. Monk agrees to investigate, and after some snooping at Max's house, Monk agrees with Linda that Jeanette's death looks suspicious, and that Max was probably involved. But Max was on the air at the time Jeanette died. How could he have done it?
