QED was shown on daytime ITV or Channel Four (Ulster Television area) and I remember that episode plots revolved around Deverill thwarting the untimely use of anachronistic inventions: one of the stories saw him trying to stop the use of an atomic missile in 1912! I can only think of 'Wild Wild West' being anywhere like this series in content, but QED had a decidedly British flavour and humour to it, even with the American actor Sam Waterston in the lead. His was a thoroughly enjoyable, frenetic presentation of a not altogether appealing character. Exciting and funny, 'QED' was cult viewing and is long overdue reappraisal. Perhaps it was scheduling, or the then current trend for 'A-Team' pseudo-violence that left this series on the shelf? Either way, it was a real showcase for Sam Waterston, whose performance might surprise those more acquainted with him in 'I'll Fly Away' or 'Law and Order.' Very definitely on my 'must get' DVD list - when that is possible - and a 'must see' if you like 'Wild Wild West' or 'Doctor Who.'
