This isn't a flaw – Lake of Sorrows works perfectly well without the ancient mystery and I do think that it's realistic that the mystery of the Iron Age man is left unsolved. In Haunted Ground, Nora and Cormac had two mysteries to solve, one ancient, one modern-day, but Lake of Sorrows only features the modern-day murder mystery.

The only complaint I have is the lack of the double mystery. The mystery this time around was a lot more suspenseful with a real sense of danger, there are fewer information dumps, the character arcs tie up pretty damn well by the end of the book and the romance between Nora Gavin and archaeologist Cormac Maguire worked better this time around, mostly because they were an established couple this time. Hart's work still comprises of great characters who drive the story forward and who each become endearing in their own way. The strengths found in that novel remained constant and the weaknesses were improved on. In all honesty, I thought Lake of Sorrows was a better novel than. The only thing that differs, however, is that this body comes with a wristwatch, marking it as belonging to the modern era.

Lake of Sorrows is the second book in Erin Hart's series of crime/mystery novels featuring pathologist Nora Gavin, this time focusing on the discovery of a man's body in a bog that seems to be an Iron Age ritual killing, similar to a very recent find in the same bog.
