I'm just being lazy, Small. If I knew which episode it was from I'd look for any other, similar images. As Spooks is only my subsidiary research topic I CBA do not have time in my research programme to trawl through every episode.
What a pity we didn't have these curtains through those loooong winter nights. But may I suggest the cushion-strapped-to-the-head look is not very becoming and you might fare better if you position yourself in front of Mr Porter the chaise longue if you're feeling enervated?
