Sunday, 8.30pm, National Geographic Do you know what a three-card monte is? Hint: it’s not a chocolate biscuit. Yes, it’s a card trick — one of the most mysterious. If the pompousness of professional card sharp and magician Drummond Money-Coutts (is it any wonder he uses the acronym?) doesn’t put you off, this is a fascinating excursion into unknown worlds of sleight-of-hand card cheats pursued from London via Paris to Bangkok. DMC started his career as a card sharp 14 years ago at Eton College. When the other lads were playing sport he was lurking in doorways perfecting card tricks. The obsession has grown in the years since his schooldays, especially after the spectre of making a fortune reared its ugly head. DMC is now the proud owner of more than 1000 modern and vintage decks of cards. He ups the ante in this documentary by making a card trick the most dangerous thing he has ever taken on. Sulphuric acid is involved.
