Documentary: Killer Women With Piers Morgan, 9pm, ITV

This is the sort of show that if you see the first five minutes of you are guaranteed to watch the entire thing, so engrossing are the stories of these ruthless women. Piers Morgan is back across the Atlantic interviewing some of America’s most notorious female murderers, in a quest to discover what drives a woman to kill. The broadcaster is pictured with Rebecca Fenton, an inmate at Lowell Correctional Facility who is currently serving life for the brutal murder of her husband Larry. In a remarkable encounter between the pair, Rebecca has an answer for everything and in a game of cat and mouse, Morgan has a crucial question: did she gun down her husband at point blank range?
