Tensions Rise in the Precinct in Castle’s “Need to Know” (Images & Scoop)

Check it out Castle fans. We’ve got some scoop and first look images from Oct. 7’s episode “Need to Know.”

The latest from ABC reveals that the episode will see Castle and the boys investigate the murder of former child star Charlie Reynolds, who rose to fame playing the lovable nerd on an early 90s High School sitcom. However, the case will take a turn when Agents Beckett and McCord arrive from Washington to take over the investigation, creating competitive tension in the precinct.

Castle questions why a washed-up actor’s death would warrant Federal scrutiny, but Beckett and McCord aren’t telling.

Meanwhile, Castle has to contend with a new face at the 12th, NYPD in Detective Frank “Sully” Sullivan (Joshua Bitton, The Pacific).

Catch it Monday Oct. 7 (10:01-11:00 p.m., ET) on ABC.
