Repeatedly she stressed that the Hello! photographs had been "stolen". At times, she seemed almost flirtatious. Mr Price tried to establish precisely which intimate moment she considered private.

Michael Douglas sat like a rock, the bouffant wings of his surprisingly blond hair peeping above a stack of legal papers. When it was his turn to take the stand he did it like the second-generation movie star he is.
Standing erect, jaw clenched, he parried Mr Price's questions in the clear, urgent, but slightly-wounded tones so familiar from films such as Basic Instinct and Disclosure.

He said that he and Catherine couldn't understand "why anybody would want to hurt us so much". This was a stirring performance.
