'Fragile Strength'

Buoyed with news of popular support, Heston meets with his defence counsel Godfrey to go over the case. However, he finds that Godfrey doesn't share his confidence. Godfrey warns Heston that the CPS must feel there is a case to answer and they can't rely on the old boys network.

Heston tells Godfrey that he can think of no mitigating circumstances to explain his state of mind. Godfrey mentions Marina, but Heston erupts - he will not have her name mentioned in court…

Meanwhile, Julia has a spring in her step after a delightful weekend with Martin. However, he arrives early to cancel lunch as his house sale is going through unexpectedly early today. Julia confesses to Karen that they'll just have to make the most of the time they have left. Martin returns and asks a shocked Julia to come to North Wales with him. She flatly turns him down.

Elsewhere, desperate to help a patient confront debilitating illness, Elaine discovers that the cause might be very close to home.
