Logan stars as Cora Felton, the eponymous Puzzle Lady, who is known up and down the land for her crossword puzzles.

So, when a blank puzzle is found on a dead body uncovered in a graveyard, the police turn to her to help them solve the mystery.

"But the eccentric Cora isn’t who she claims to be, and as she throws herself into a murder case that has the town’s residents baffled, she starts to gather allies and enemies in equal measure," reads the official synopsis.

Speaking about her character, Logan said: "She’s not great [at detective work] to start with, but by the end of the first episode she decides she’s actually quite good at the sleuthing, and she does eventually manage to help solve quite a few of these strange murders, so she gives herself a pat on the back… even though the police are fed up of her interference!

"I think they might be a bit jealous of the fact she tends to get it right. She starts off in a small way, but then gets right into it and sees crime solving as her forte."
