Case Sensitive - 2011

Two part crime drama Case Sensitive begins when Detective Sergeant Charlie Zailer and Detective Constable Simon Waterhouse are called in to investigate the shocking deaths of a mother Geraldine Bretherick and her five year old daughter Lucy.
Unsure whether it is murder or suicide Zailer and Waterhouse must examine every angle, including putting husband Mark under close scrutiny. Meanwhile Sally Thorne who previously had an affair with Mark decides to get back in touch with him only to discover that the man she believed to be Mark is someone else entirely!
Good to see a Sophie Hannah adaptation, she pens a nice line in psychological thrillers and there is a nice line in antigonism between Zailer and Waterhouse too.

Synopsis

Sally is watching the news with her husband when she hears a name she ought not to recognise: Mark Bretherick. Last year, a business trip Sally had planned was cancelled at the last minute. Desperate for a break from her busy life juggling her career and a young family, Sally didn't tell her husband that the trip had fallen through. Instead, she booked a week off and treated herself to a secret holiday. All she wanted was a bit of peace - some time to herself - but it didn't work out that way. Because Sally met a man - Mark Bretherick. All the details are the same: where he lives, his job, his wife Geraldine and daughter Lucy. Except that the man on the news is a man Sally has never seen before. And Geraldine and Lucy Bretherick are both dead ...
