An unexpected turn of events will leave Joan Watson in shock when she finds out her stepfather has written a crime novel based on her and Sherlock Holmes' works in the upcoming episode of "Elementary", titled "Miss Taken".

CLICK HERE to watch why Watson's stepfather decided to write about the cases of Sherlock and Watson and how Watson will deal with the situation.

As mentioned by TV.com, Watson is enraged when her stepfather writes a crime novel based on her work with Holmes without her knowledge.

Meanwhile, Sherlock and Joan investigate a retired FBI agent's murder and learn it is linked to an unsolved case from the victim's career.

Even though Watson's stepfather assures her the story doesn't contain any critical information, Watson is angry as he didn't take permission from either her or Sherlock before writing about them.

Elsewhere, Sherlock is involved in a complicated murder case of the FBI agent and no matter how hard he tries, he is not getting enough clues to provide him any lead. The case is affecting him adversely and he is getting more reckless.

In the previous episode, titled "The Cost of Doing Business", a sniper shot nine people, killing four, in the financial district while Morland visited Sherlock at Brownstone to offer his help.

In the shooting that initially appeared to be random, a target named Frank Bova emerged, who was a plumber by profession. Morland's contact in Interpol, Lukas, found out that the shooter, Gagnier, was hired and paid in a Swiss bank account by a shell subsidiary of Dynastic Energies.

After a false lead, it turned out that the CEO of Dynastic Energies, Bill Wellstone, had Frank killed because Bill's lawyer's wife Sarah, with whom Bill was having an affair, had left him for Frank.

Evidence was found in the form of gun oil smear in the golf bag Bill used to smuggle in the sniper rifle for the assassin. Later, Morland had dinner with Lukas, who voiced his suspicion that Morland had not been helping Sherlock out of goodness, but was rather risking Sherlock's life.

Lukas demanded €5 million to keep his mouth shut, and Morland threateningly revealed he had Lukas' predecessor killed for a similar reason.
