Fans of the crime drama television series 'Castle' can expect to see a lot of fun going on when the show returns with Season 7 episode 11 entitled "Castle P.I." on Monday, Jan. 12, on ABC following its brief winter hiatus. In fact, fans will see Beckett and Castle in a stiff competition in the all-new episode.

In the previous episode, which also happened to be the mid-season finale, viewers saw Castle being eased from his responsibilities at the New York Police Department to enable him to pursue a new career - taking up the profession of a private investigator.

According to Christian Today, in the upcoming episode on Monday night, viewers will see Castle approaching Beckett in connection with a case. Apparently it will look as if they are working together in solving the case, but actually they will get into a competition regarding who would solve the case first. As a result, Castle and Beckett will do everything possible simply to outdo each other.

Carter Matt reports that while Beckett possesses the requisite manpower that will help her solving the case faster, Castle is able to proceed with the investigation without having to follow any rules. TVLine says that the duo will employ unusual procedures with a view to win the competition. While Beckett will be seen getting someone drunk with a view to obtain information, Castle will turn to breaking into an office.

Meanwhile, explaining why it was necessary to turn Castle's character into a private investigator, show creator David Amann told TV Guide, "We thought it would give us some opportunities to upset the apple cart a little bit in terms of the Castle-Beckett professional relationship. We were looking for an interesting way to have Castle get into trouble. He kind of operated outside the lines in Episode 10, so we felt that like it was justified that he would be punished for that."

Besides solving the case, fans will find it interesting to see how Castle works his way back to the NYPD.
