Couples' Therapy - BBC Two - 10pm
This fascinating new fly-on-the-wall series goes inside the office of a US couples therapist as she explores their relationship issues over 20 appointments.
Dr Orna Guralnik speaks to real couples who are struggling with issues including whether to become parents, what happened on a traumatic birthday, and if they should stay together at all.
As more of the relationships are revealed, first impressions are challenged and how the couples manage to work things out - or not - becomes addictive viewing.
Only Connect - BBC Two - 8pm
The super tough quiz stages its second semi-final tonight where the last team through to the series final will be named.
Up tonight are the Data Wizards and the Ramblers, who'll be hoping for a slightly easier semi-final than last week's fiendishly difficult walls.
The Killer Nanny: Did She Do It? - Channel 4 - 9pm
Late last year, Channel 5 aired a documentary about British nanny Louise Woodward who was convicted of the involuntary manslaughter of Matthew Eappen, an eight-month-old baby in her care when she worked in the US as a teenager in 1997.
This is Channel 4's turn at revisiting the case and in this second episode of three, it looks at how the defence argued Woodward had not shaken Eappen to death, as well as interviewing jurors about their decision.

The documentary series looks at what life is like as a Brit living in Dubai and the luxurious lifestyles that are possible.
In tonight's episode, a Geordie supermarket shelf-stacker gets the offer of a lifetime when he is presented with a job opportunity that could completely change his future while on holiday in Dubai.
