James (Author) Anderson: The Affair of the Thirty-Nine Cufflinks [2009] paperback

And then there were eight - Understandably, Lord Burford had some misgivings about hosting another house party at Alderley, his beautiful country mansion. After all, the previous two could at best be described as disastrous. But with family members travelling down for a relative's funeral, the Earl really had no choice but to offer them accommodation. It didn't take long for things to start going wrong. One of the guests claimed she had knowledge that would ruin the others' reputations, but luckily nobody took her seriously enough to take offence. At least, that's what they thought up until her body was found.
