Is Marley's Ghosts coming back?

Marley's Ghosts has a very intriguing premise - Marley has a rare gift that comes with mixed blessings. She can talk to the dead, which sadly now includes both her husband Adam, her lover Michael as well as the local vicar. Dead awkward.

So begins a bizarre ménage-a-quatre, with Adam, Michael and the vicar all moving in, albeit in ghostly form, to Marley's haunt, sorry, home.

Naturally Marley isn't crazy about this new set up - but all looks rosy again when the ghosts convince her that they're just a figment of her overwrought imagination, and for a moment she really believes they've gone. But, no, these apparitions ain't evaporating - they're going nowhere.
