I was in the mood for a darker themed book still involving Christmas that I could finish before the big day, and this one fit the bill perfectly. Fairly short, crisp, and intriguing. I wasn't aware that I was jumping into a series before I started. The characters were hard to keep track of, as there are many. I had to look back quite a bit. I think this one would be best enjoyed read following the three others before it. Because I was a little lost on the characters and their history, I found myself paying more attention to the case. It's a doozy! Bleak and intricate but easy to follow, dark enough to make me stop and think. My detective skills failed me with this one, and the ending left me surprised.
Recently promoted DI Bulmer and CI Calderwood have a brutal new case on their hands: an older partially disabled couple are found killed in their own home. They're found with Christmas cards... nailed to their heads.
After discovering that these aren't the first murders featuring this macabre calling card, they become convinced that they won't be the last, either. Solving this case will involve lots of digging into the past, but most don't want to talk.
While I wished for a clearer background on the characters, the strange case and crazy ending made this book for me. 3.5 rounded up to a 4 here.
I received a copy of this book from Net Galley and Endeavour Press, thank you! My review is honest and unbiased.
