In Eureka, Anthony Quinn gives us all the enjoyable froth we could hope for in a novel about making a film in the 1960s — champagne, drugs, threesomes, gangsters, a Silver Cloud Rolls-Royce, hula-hooping girls and Pucci scarves flung over smears of vomit. Underneath, however, lies an intellectual question. The film is an adaptation of Henry James’s ‘The Figure in the Carpet’, a story about obsessively trying to understand the secret key that unlocks an author’s work: ‘The idea that governs the whole and gives it meaning… a string that my pearls were strung on.’
