"The marriage was in all ways but one a great success. What Sybil didn’t know was that in 1949, the same year they got married, he met the actress Claire Bloom — then aged 18 — and quickly fell in love. Their relationship was finally consummated after he bet a fellow actor a pint that he could take Bloom’s virginity.
Bloom recalled: ‘We made love quietly in my room with my mother sleeping upstairs. Richard left me in the early morning to go back home, and I went to sleep happy and childishly thrilled that I was a “woman” at last.’
She gave him the key to the house, and Burton would often sneak into her bedroom. Before sunrise, he’d go back to Sybil, telling her he’d been out drinking all night with friends."
