This week Annie stumbles across the oldest ghost she's ever met - Sykes.
Sykes is a World War II veteran trying to help Annie dodge death and all its agents. Here's a sneak peek of the pair in action as Sykes teaches Annie to embrace her ghostly powers and learn to read auras.
I've been reading the auras of the blog team all morning. Seems to be saying they want a raise and more days off... Nope, must be doing it wrong. Back to work blog team.
Do you like the look of Sykes? And do you think he will be good or bad for Annie? Leave us your comments below...
And don't miss episode four this Sunday 9pm on BBC Three.
