Mark Gatiss plays Sherlock Holmes' brother, Mycroft Holmes, on the BBC series Sherlock Holmes. As much as I keep meaning to check it out, so far I haven't had a chance to do so.
Still, considering my deep and abiding love for another BBC channel show, Downton Abbey, I have no doubt I'm going to be a fan, so when our friend pointed out Mark as someone from Sherlock Holmes, I knew we had to meet him. As an extra bonus, he ended up giving me his gift bag from the event later that night. WIN!!! :)
