John Humphrys talks to successful people who have weathered storms in their careers. Marjorie Lambert talks about how her foster daughter shattered her life. Marjorie took on difficult teenagers and tried to give them a better life, but when one foster child made accusations of sexual abuse and began a string of threatening phone calls, her life was sent into turmoil. It took a further 10 years to discover that vital and disturbing information about the girl's past had been withheld - information which would have stopped her fostering the girl in the first place.
