Heather Lind has booked a ticket to Sleepy Hollow.

According to TV Line, the actress (Turn) will guest star on Sleepy Hollow Season 2 Episode 5 as Mary Wells, an ex-girlfriend of Ichabod’s from England.

A rather unstable ex-girlfriend, we should say, as the character initially comes across as pleasant and sweet... only for a far more ominous, jealous side to eventually be exposed.

Lind portrays Anna on the aforementioned AMC drama and will film her Fox stint prior to shooting Season 2.

Matt Barr and Sakina Jaffrey will also play key roles on Sleepy Hollow this fall, with the surprise hit having its episode order upped from 12 to 15.
