“HARRY Pearce…”

The poignant last ever episode of Spooks has just finished.

There will be no more.

Nicola Walker summed up my feelings in an interview this week when she said:

“The storyline for this last series is the right ending for the show.

“I don’t know if it’s going to please everybody but it’s a very clever and grown up end point.”

Peter Firth's final hour as Harry Pearce.

“YOU and I, we’re made of secrets.”

Ruth Evershed and Harry Pearce face the final curtain together.

Standing by a familiar estuary as we hold our breath to see what will happen.

Spooks series 10, last ever episode.

The Grid: Class of 2011

HARRY and Ruth are sitting together on a park bench.

Ruth: “Do you know what it’s like to feel something for someone and then one day realise you don’t even know them?”

Harry: “You do know me. You know all the important things.”

Spooks series 10, episode four.

In which we learn battle-weary Sir Harry has so many more secrets.

Geoffrey Streatfeild as Calum Reed

SPOOKS returns for its farewell series at 9pm tonight.

With the BBC1 schedulers placing Sir Harry and his team head-to-head against ITV1 drama sensation Downton Abbey.

So far I’ve seen the first two episodes of both Spooks 10 and Downton Abbey 2.

As I’ve said before, I hope drama fans ignore the hyped-up “rivalry” and find the time to watch both.

Geoffrey Streatfeild joins the Spooks regulars this evening as Calum Reed.
