According to Variety, Walden Media has acquired romantic action-comedy "Sherlock's Secretary" from reality-TV maven Bruce Nash and his Nash Entertainment shingle.

Nash and Bob Kosberg, who heads Nash Entertainment's film arm, developed the idea together and will produce, with Steve Kaire as co-producer. Exec-turned-scripter Julie Golden will pen the screenplay.

The story is inspired by the many letters sent from all over the world to Sherlock Holmes' London address, 221B Baker St., asking the great detective for help in solving real-life crimes. "They think Sherlock is alive and that he's real," Nash said.

"There was a bank on that site that got so many letters that they hired somebody to be Sherlock's secretary and answer the letters as if he were really alive. I always wanted to do a new take on Sherlock Holmes, but there was nothing to do new until we found those letters."

The pic will center on a man living at that address who decides to take on a case from one of the letters. In becoming a detective, his whole life is turned upside down.
