This summary is from the starred review at Booklist...
The amateur detective is Rex Graves, a Scottish barrister, fond of Sudoku puzzles and Latin quotations... Although set firmly in the present, with numerous references to the Iraq War, this tale reads like a classic country-house mystery. Rex and the others are snowed in at the Swanmere Manor hotel in East Sussex, England. Being the last to arrive (on two tennis rackets lashed to his feet à la snowshoes), Rex immediately hears of the unexpected demise of one of the other guests. Even though they are in touch with the outside world, the authorities instruct the hotel staff to keep the body in a cool room with the windows open.A guest who is a paramedic takes Rex aside and voices his suspicion that the death was not a heart attack, but poisoning. Rex takes it upon himself to unravel the mystery while waiting for the authorities to arrive.
I am of two minds about this book. On the positive side, it kept me entertained and my interest in the story did not lag. Unfortunately, I had several niggles that I could not ignore. There were problems with the logic throughout, and (most of) the characters were not convincing or very interesting. The denouement did not seem to make sense to me and the way it was handled was too frivolous and light. The attitude seemed to be "let's get this done with and move on to the farewells."
There were some characters I liked. Two of the guests, Anthony Smart, an antique dealer, and Patrick Vance, Smart's gay partner, were charming and the most fun. I also like Clifford, who "just creaks along doing odd jobs in the house and garden. He lives alone in the lodge by the gate." Thus I have some confidence that, in future books, the author can come up with both a more convincing story line and characters that interest me.
Other positives: It is short, and the excerpt from the second novel that is included at the end of my edition reads very well.
My quandary is that, not only do I have mixed feelings about the book, I find that reviews are divided. About half the reviewers find this a fun cozy read, set in contemporary times but written like a traditional Golden Age mystery. The other half have similar complaints to mine. Also, the author has published eight books in this series, and this says to me that there are people enjoying the series. So, while I cannot recommend the book based on my experience, I can suggest that you give it a try if you think it may appeal to you. I will list some links to reviews at the end.
The second book in the series is set at an exclusive nudist resort in the French West Indies (Murder in the Raw). That sounds interesting. The third book is set in Florida (Phi Beta Murder), where Rex Graves' son is attending college. In the fourth book, Murder on the Moor, Rex finally spends some time in Scotland.
