Here is British humour at its very wittiest and cutting.

The machinations of the team at Prentiss McCabe are a joy to behold as they spin the latest challenge.

The dialogue is edged with a delicious sprinkle of smugness. Not that you'd like to meet any of these people - they're utterly self-serving, and are a sharp reflection of the slick wheelings and dealings, counter-dealings, backstabbing, Machiavellian world that I could only imagine might take place in such a real world business.

I came late to this series, only discovering it last year and, I can thoroughly recommend it. Like Fawlty Towers, the limited production of episodes will ensure this remains a classic.
