I'm a big fan of the brilliant "Sherlock" BBC TV series. The stories are new, the characters are modern and yet the style of Conan Doyle is omnipresent. Quite the opposite of the absolutely atrocious Guy Ritchie movies!
One of the funny things in the latest episode, "A Scandal in Belgravia", is Sherlock's mobile phone ringtone. Check it out here:
Coming from your phone's speaker, the ringtone will never sound the same as it does in the movie, but you can give it a try!
