The synopsis says that in'"Bones' Season 10 Episode 8 titled "The Puzzler in The Pit," viewers will find Booth (David Boreanaz) and Brennan trying to resovle the murder case of a puzzle master, who was reputed for producing extremely challenging crossword puzzles for newspapers.

A promo clip of "The Puzzler in The Pit" released by FOX goes on to hint that that the puzzle master could have been killed for the impossible puzzles he created. A possible motive for the murder, it suggests. But things are likely to become somewhat complicated when Booth and Brennan find out that the puzzle master was suffering from mental illness when he was murdered.

In the 'Bones' Episode 7 titled "The Money Maker on the Merry-Go-Round," viewers saw that after discovering the badly mutilated human remains under a merry-go-round, the team initiates a probe into a mysterious hedge fund company and its owner, who was reported to be the victim's employer.

Matters become difficult in 'Bones' Season 10 Episode 7 as Agent Aubrey (John Boyd) takes a personal interest in the case.

The synopsis of 'Bones' Season 10 Episode 8, however, suggests that "The Puzzler in the Pit" will be a little different and, it will not be all fun and games.
