BBC ' Sherlock' Season 4 Release Date & Cast News: Co-Creator Mark Gattis to Appear in Holmes-Inspired Concert

Sherlock Holmes, the Hubble space telescope and the Ibiza dance scene will inspire concerts featured at the BBC Proms, a two-month music festival starting July 17.

"A Musical Mind," the concert held on Aug. 16, will feature music mentioned in Arthur Conan Doyle's infamous tales about the world's favorite fictional sleuth, Sherlock Holmes. The prom will also employ up-to-date music from the BBC "Sherlock" series, starring actors Benedict Cumberbatch and Martin Freeman, highlighting Holmes as a violinist and an opera aficionado.

Mark Gatiss, co-creator and co-producer of "Sherlock" who also plays the role of Mycroft, on-screen brother to Holmes, will read excerpts from the books at the prom. Also, mezzo-soprano Christine Rice will channel Holmes' nemesis, opera singer Irene Adler. The Sherlock-focused concert, "A Musical Mind," will be set in the Royal Albert Hall, which was mentioned in at least one of Doyle's stories. The concert will include violin performances by Jack Liebeck (Paganini's "Caprice No. 24"), singing by Christine Rice ("Wagner's 'Höre mit Sinn' from Götterdämmerung") and performances by others also influenced Doyle's stories and the hit BBC series.

The concert will hopefully tide some fans over, while the rest hungrily await the premiere of the time-warped Christmas special and the fourth season of the series, which won't return until 2016.

Meanwhile, the series' creators, Gattis and Steven Moffat, and actors have sparingly dropped hints, and in doing so, fans have learned that John Watson's new bride Mary may die soon, leaving Watson a widower.

"While we play fast and loose with the original stories, we generally follow the trajectory of what Conan Doyle did. So [Watson] gets married and then Mary dies -- so at some point presumably she'll die," Martin Freeman, who portrays Watson, told The Telegraph.

Additionally, creators and actors have teased that the upcoming season will involve devastating tragedy. However, the storyline for the upcoming season, which will involve three 90-minute episodes of "Sherlock," have yet to be revealed.
