SUNDAY: Case Histories, BBC1’s new crime drama starring Jason Isaacs, debuted with more than 5.4m viewers - but was beaten by the second episode of ITV’s Scott & Bailey.

The six-part series, adapted from Kate Atkinson’s Brodie novels, launched with an audience of 5.42m (20.9%) over the 9pm hour, according to overnight Barb figures supplied by Attentional.

It held its audience almost resolutely across the hour and was above the channels’ slot average of 5.06m (19.45%) for the year to date.

Case Histories was, however, murdered by the competition. The second part of detective drama Scott & Bailey averaged 6.14m (23.66%) across ITV1 and ITV1 HD in the 9pm slot. An additional 314,300 (1.63%) watched on ITV1+1.

Despite growing its audience over the 9pm hour, it was nearly 1.8m viewers down on last week’s launch audience of 7.92m (31.67%). The debut did however enjoy a strong inheritance from Britain’s Got Talent.
