Good police/detective story involving one old and one new mystery, and two different police units. A bit confusing and I had to replay some of the audiobook to clear up some confusion. . I had to set the narration speed at 75% because sometimes the story was read in a very fast pace. The story line was good and well thought out and the characters well developed, especially Tobias whose OCD tendencies make him very endearing. No other books on Amazon by this author so maybe this is his first book. I hope to see more of his work in the future.
