Meet the cast of Sherlock series 4
From the box office blockbusters to the all-important supporting stars, here's who's who in the fourth series of Sherlock and where you may have seen them before
Euros Holmes – Siân Brooke
Meet Euros Holmes What do we know about Sherlock and Mycroft's secret (and possibly villainous) sister, who reveals her true identity towards the end of episode two? Well, we know she's a master of disguise, having played John's bus stop love interest, his therapist and the fake version of Culverton Smith's daughter Faith, who spends an evening eating chips with a drug-addled Sherlock without him ever recognising her. That suggests it may have been some time since Sherlock's last seen her but she is clearly inextricably woven into his life, with Mycroft telling us in the trailer for the series finale "Every choice you've ever made, every path you've ever taken, the man you are today, is your memory of Euros."
What else has Siân Brooke been in? Most notably for Sherlock fans, Brooke's stage career has included a turn as Ophelia, girlfriend of Benedict Cumberbatch's Hamlet in the recent Barbican production. On TV, she's had roles in Doc Martin, New Tricks, Silk, Garrow’s Law, Lewis, Man Down and most recently in Channel 4 comedy Not Safe for Work and The Moorside Project. Read her full bio here.
