Sherlock Series 4 - Michael Price & David Arnold - Seven years from it's debut, 'Sherlock' is a worldwide phenomenon licensed to over 225 territories and equally popular with cinema showings alongside TV transmissions. In the UK Season 3 was the most watched TV drama series since 2001 attracting 11. 8m viewers. Sherlock is a series that doesn't wallow in it's success as David Arnold explains, "I think we both want to move it on every time. If the show stands still then the music does too and it all grinds to a halt... so we are always trying to find something new to do with it". "If David Arnold and Michael Price did not exist, it would be necessary for man to invent them. Their contribution to Sherlock is immeasurable. Thrilling, cheeky, sinister, playful and simply world-class - the music's not bad either" - Mark Gatiss (Sherlock and League Of Gentlemen creator).
