Television can be a storehouse of treasures, and one of its best kept secrets was a show called Charmed. Despite being scheduled at all hours, the series steadily built up a dedicated and vocal audience who became hooked by its beguiling and seductive power, attractive visuals and gentle wit. Charmed is the story of the four Halliwell sisters, Prue (Shannon Doherty), Piper (Holly Marie Combs), Phoebe (Alyssa Milano) and Paige (Rose McGowan). Together they are the Charmed Ones and they are sworn to protect the innocent. In Triquetra, best-selling author Keith Topping explores every episode, revealing the triumphs, the goofs, the guest stars, the intake of nicotine and alcohol, and generally gets under the skin of the Halliwell sisters and their lives, loves and spellbinding adventures.
