I was browsing magazines online and "Another Litlle Christmas Murder" by Lorna Nicholl Morgan was recommended as a Christmas read. It's currently 99p on Amazon in Kindle format.
"A classic country house mystery republished for the first time in nearly seventy years. Perfect for fans of Murder at the Old Vicarage and Partners in Crime.
When Dilys Hughes finds herself snowbound in the middle of a bleak and lonely stretch of Yorkshire, she has no option but to accept help from passing motorist Inigo Brown, who is on his way to visit his uncle.
Arriving at his uncle's remote country house, Wintry Wold, the couple encounters a less than warm welcome from Inigo's new young aunt, Theresa. Why is she reluctant to let Inigo see his uncle, and is he really as ill as they are told?"
