My only complaint is that I'm here waiting for a sequel. I didn't know this was going to be a series because of the time -travel I thought I was a one off--but when there was only half an hour left of the audiobook I realized I was looking at a likely cliff-hanger situation.
Happily, the murder mystery is solved it is just the overarching mystery of the central character that is left. The Sherlock Holmes, but in Scotland vibe was fabulous.
