I’m not an agent for one of the government alphabet agencies, but this woman’s knowledge and behavior feel realistic to me. Often in stories with these types of leads, the protagonist is a little too amazing, but that’s not the case here. Also, not all time travel stories flow so easily. I did notice the killer’s word slip and figure out some in the mystery of the murders, but so much of the mystery did keep me on edge. I plan to continue the series.
