PHAO BUACHAN SMILES sadly through a web of wrinkles, spits a jet of bright red betel juice through what's left of her crimson teeth, and regards me with a rheumy eye. 'I can't speak about my son without begging his permission,' she says. 'I'm scared the snakes will come, and they'll be angry.'
She hands me a candle and a stick of smouldering incense, and we pick our way through a building site at the back of her wooden house to a white shrine dappled with shards of coloured glass and tiny mirrors. She nods. I kneel, mumble a few words and deposit the candle and incense in a jar of sand. Her prayer is longer, a rambling entreaty punctuated by slow-motion prostrations. When she's finally finished she stands, smiles again and says, 'Now we may speak.'
Her son, Boonreung Buachan, was the 'Snakeman of Sisaket'. In 1998, he had a fleeting taste of international fame when he appeared in the Guinness Book of World Records for spending seven days in an enclosure with venomous snakes.
Before and after setting the record - which still stands - Boonreung made a living by performing throughout Thailand. In his hour-long shows, he would pluck cobras from wooden boxes and drape them round his neck, stroking and kissing them as he kept up a steady patter of cobra lore. He would milk their venom, letting people get close as the deadly, viscous liquid oozed from scimitar fangs.
The sense of danger was heightened for those who knew him because Boonreung was epileptic and prone to seizures. While his friends say he never had an attack during a show, the risk weighed heavily on the snakeman's mind.
International attention was to come his way just once more. Unfortunately, he wouldn't be around to enjoy it. Three months ago, Boonreung, aged 34, was bitten by one of his pet cobras while putting on a show for three tourists. He collapsed in the dirt beneath his parents' house in Ping Pong village, a parched corner of one of Thailand's poorest provinces. By the time he was taken to hospital, his respiratory system had all but shut down. He never recovered.
