Just in time for Halloween, the scientific world of BONES meets the supernatural world of SLEEPY HOLLOW in a crossover event to thrill the living, the dead and everything in between, airing Thursday, Oct. 29. On BONES (8:00-9:00 PM ET/PT), the grisly discovery of human remains lead Brennan (Emily Deschanel) and Booth (David Boreanaz) on a hunt for clues, during which they encounter Ichabod Crane (Tom Mison) and Abbie Mills (Nicole Beharie), searching for answers of their own. Realizing that they are after the same evidence, they team up to solve the mystery. Then, immediately following on SLEEPY HOLLOW (9:00-10:00 PM ET/PT), the intrigue continues as Ichabod’s old nemesis is back from the dead. Ichabod and Abbie need advanced forensic help and expertise to stop him and turn to Brennan and Booth to unlock 18th century secrets using 21st century science.
