'The Cook'

The episodes before "Mr Raleigh Sinclair III" were "The Cook," which aired in the US on Jan. 31 and "Invisible Hand," which was broadcast on Wednesday. "The Cook" showed Red and Liz working together to hunt down Tom Keen's (Ryan Eggold) killers. However, she started to have doubts about Red and even questioned his true intentions. As for the Task Force, they recruited an arsonist to assist them in catching another one. Slovan "Slick" Naim directed this episode, which was written by Peter Noah.

'The Invisible Hand'

"The Invisible Hand" featured Liz finding a crucial clue about the investigation of Tom's death. Meanwhile, a lot of bodies were found in abandoned woods. This led Red to think that the group behind it is The Invisible Hand. He told the Task Force about the said group that targets people who do morally reprehensible acts that are still considered legal. Plus, Red helped out one of his employees. Lukas Reiter and Jonathan Shapiro wrote this episode, which was directed by Spader's "Pretty in Pink" co-star Andrew McCarthy.

"The Blacklist 5" airs at 10:40 pm AEDT in Australia every Monday on the Seven channel. In the US, it airs on NBC from 8-9 pm on Wednesdays. Stay tuned for upcoming "The Blacklist" spoilers.
