Sherlock series 3: My Mad Fat Diary’s Sharon Rooney to join cast

The star of the recent E4 drama is set to play a character called Laura in the BBC1 detective drama

Sharon Rooney, last seen in E4’s My Mad Fat Diary, is to join the cast of Sherlock – most likely for the series three finale.


Rooney will play a character named Laura according to her online CV, although other details of the part remain scarce.

“We won’t be saying any more about her role at this point,” a spokesperson told, but there are good reasons to believe Rooney will appear in the concluding instalment of the three-part series.

Episode one of Sherlock is already in the can, with the second part set to wrap soon prior to a summer break. And since Rooney has not previously been linked with the series (despite several more high-profile names being leaked) it seems likely her character is bound for the final episode.


Sherlock series 3 is due to air on BBC1 towards the end of the year.
