SPECTRAL SITCOM

Ghosts, 8.50pm, BBC1

THE funniest comedy on television returns for a new, fourth series — and if you have somehow managed to miss out on the previous three, they are all available on BBC iPlayer. As we head back to the haunted house, Mike and Alison (Kiell SmithBynoe and Charlotte Ritchie, pictured) are feeling the strain as they prepare to welcome their first guests to the new B&B. Meanwhile, the Plaguers below the stairs make Romantic poet Thomas (Mathew Baynton) their unlikely idol, and Pat (Jim Howick) teaches Mary (Katy Wix) the joys and pitfalls of package holidays.
