Christmas is approaching but also death as at Planet Burger a man is stabbed. But with no why and how it makes the case difficult to investigate
Then DCI Colin Andersons' potentially disastrous Christmas is saved. As up in the highlands, at Glen Riske, a body is discovered in one of the holiday lets. Could it be murder.
I found the mystery part of the story, interesting and enjoyable. But for me there was too much extraneous, and boring details about the Anderson and Costellos' personal lives. So overall I liked the mystery, but didn't love the final story. Also the two main police characters are really not that likeable.
A NetGalley Book ( )

A family man's stabbing leaves Anderson and Costello and their teams baffled. The perpetrator left no clues. No motive emerges. No witnesses identified themselves. Two more bodies show up a week later at a cottage where the family intended to spend Christmas. Investigation uncovers dislike for these victims. The novel spends a little too much time discussing problems within the detectives' families and explored some things which needed omission to tighten the novel. Those who read previous series installments may appreciate some of the detectives' family problems more than I did. I did not feel I knew the detectives because I missed earlier installments. I may try the first couple of books in the series to see if I warm to the series. If so and I continue reading the series, I may revisit this installment to see if it improves with the background from earlier cases and without the distractions of reading in a time of COVID-19. I received an electronic copy from the publisher through NetGalley in exchange for an honest review. ( )
