CBS network's police procedural drama television series, "Blue Bloods", comes back tomorrow with a fresh exciting episode from its seventh season, which fans speculate would take them to another level, especially now that a new murder suspect is set to tangle the lives of the characters.

The previous episode of "Blue Bloods" aired last week featured a detectives Danny Reagan, portrayed by Donnie Wahlberg, and Maria Baez, played by Marisa Ramirez, on an investigation regarding the murder of a gang leader. It has been revealed in "Blue Bloods" season 6 that a romance between an ex-con and a parole officer may just be an alibi to cover up the murder.

Danny Reagan's father, Frank, portrayed by Tom Selleck, thought of a way to avoid more possible violence through interacting with a competing leader of a gang known as Method Man. The previous episodes of "Blue Bloods" season 6 have shown the opposing gang leader to be in prison for the killing of Deputy Chief Donald "Don" Kent (Dennis Haysbert).

In the upcoming episode of "Blue Bloods", season 7, a guest star will be appearing to portray the role of a murder suspect. According to a report from Yahoo, Actor Robert Sean Leonard, who previously starred on Fox's drama series, "House", will be appearing on the upcoming episode as Charles Beard, a suspect on a murder case.

It as also reported that viewers and fans will also see Danny Reagan and Maria Baez to work on another murder case on the fifteenth episode of "Blue Bloods" season 7.

Meanwhile, according to Carter Matt, actor Tom Selleck, who portrays the main character, Frank, was long rumored to be departing the show. Because of this, fans have speculated that if Sellek will indeed leave "Blue Bloods", there will be a chance that his character's son on the series, Danny, will be promoted and take over his position.

Otherwise, it has also been speculated that the show might hire another actor to play Selleck's role, if his departure from "Blue Bloods" season 7 will be confirmed. The source said that his exit could also change the plot line of the series and the events that surround the characters.

"Blue Bloods" season 7 episode 15, "Lost Souls", airs on February 10, 2017 on CBS.
