Catherine Driscol

Catherine Driscol is a mentioned character in the series Sherlock. Although never appearing in person, she had a major effect when it came to the events of the episode of "His Last Vow".
==History==
In 1982, a fifteen-year-old Catherine Driscol corresponded with Lord Smallwood. The pair of them would exchange letters and she even sent him photographs. She looked older than her age, and he was at the time unaware that she was underage. When he discovered the truth, he cut off communicate. Smallwood would later marry a woman named Elizabeth and the pair had a daughter together. Smallwood told his wife the truth of what happened, and informed her of the letters contents. She stood by him and the situation wasn't made public at the time. What became of Catherine later in life is unknown, although she never bothered the Smallwood family.
Somehow the letters and photographs were obtained by corrupt media mogul Charles Augustus Magnussen, who would often gain information on major figures in order to blackmail them to do his bidding. Although he didn't keep the physical copies, he used his mind palace to store the information when the time was needed.
In 2014, 32 years following the last correspondence between Smallwood and Catherine, Magnussen used his knowledge to blackmail Elizabeth as she is part of the parliamentary committee investigating his activities. This led to Elizabeth to turn to consulting detective Sherlock Holmes in order to get the letters back and work out a way to stop Magnussen. Despite Sherlock's best efforts, Magnussen would end up reporting on Smallwood and Catherine's relationship to the public, which caused Smallwood to take his own life. Sherlock would later stop Magnussen once and for all when he shot him dead on Christmas Day 2014, upon realising Magnussen only stored his blackmail information in his head.
