As the nights draw in, it's the perfect time for some cosy crime - and our latest book choice will fit the bill.

The Murder At World's End has been described as Downton Abbey meet Knives Out, and is the debut adult novel from bestselling children's author Ross Montgomery.

Sara chats to Ross about his fascination with the Victorians, plotting a murder mystery and how he managed to get Sir Derek Jacobi to read his audiobook.

We also get a sneak preview of said audiobook, and Ross gives us a top book recommendation as well!

Here's the blurb for 'The Murder At World's End'

All eyes turn to Stephen Pike, Tithe Hall's newest under-butler. Fresh out of Borstal for a crime he didn't commit, he is the wrong man in the wrong place at the wrong time. His unlikely ally? Miss Decima Stockingham, the foul-mouthed, sharp as a tack, 80-year-old family matriarch. Fearless and unconventional, she relishes chaos and puzzles alike, and a murder is just the thrill she's been waiting for.

Together, this mismatched duo must navigate secret passages, buried grudges and rising terror to unmask the killer before it's too late...
