Barclay and Suter have the same electric chemistry that Small and Parker once possessed, and by the final episode of the season, it feels like they’ve finally found the common ground that sets them up for even better plotlines.

Lynely will succeed if it mines the differences between Lynley and Havers and leans on the chemistry between Suter and Barclay.

It gets motoring in later episodes. And while no one asked for the modern-day return of detective Beau Brummell, it’s worth a look. If only as another pleasantly inoffensive pebble on the shoreline of the contemporary TV seascape.

Everything, in short, is as it should be – for fans of the books, for fans of the old series and for fans of undemanding telly. Deo gratias.

While it occasionally touches upon adult themes, there’s still a familiar cosiness which suggests it should be occupying Call the Midwife’s pre-watershed Sunday evening slot instead. .... But its refreshingly straight-forward storytelling and abundance of old-school charm should help reel in both a new generation and those who vaguely remember the original.

There would be something reassuring about this throwback, if it were better executed. Instead, the eye is drawn constantly to the limitations: the performances, the writing, the convoluted mysteries.

Lynley (BBC One) is a bland but serviceable detective drama if you come to it with no expectations.
