 He returned to writing scripts for British television , including Gentry with Roger Daltrey for ITV in 1987 , and the 1989 adaptation of Susan Hill 's novel The Woman in Black for transmission on ITV on Christmas Eve . Lynne Truss , reviewing a repeat broadcast of the production on Channel 4 for The Times in 1994 , wrote that : " Clip @-@ clop is not usually a noise to get upset about . But it will be an interesting test , today , to go up behind people and whisper ' clip @-@ clop ' , to find out whether they saw The Woman in Black last night . People who made the bold decision to watch this excellent drama will respond to any ' clip @-@ clop ' by gratifyingly leaping in the air and grabbing the backs of their necks . " The adaptation nearly went unmade ; Kneale had written the script in ten days but been advised by his agent to wait before submitting it to the producers Central Independent Television so that they would not think he had rushed it . When he did submit the script three weeks later , he discovered that Central had been about to cancel the production as they had assumed that Kneale , then 67 , had not been able to complete the work due to his age .
