A cold case with nothing new but the request to delve into it again.
A ten-plus year-old case that was perhaps allowed to languish due to less-than-diligent police work, apathy, and the fact that the best detective in the region was never on the original investigative team.
Even if you aren’t fully vested in Michael Lister’s writing, or John Jordan’s investigative prowess, know that you’re getting a well written whodunit, replete with multiple suspects, plenty of opportunity, too much motive, and… very few details and sketchy memories. A proper procedural by a highly skilled author. Lister has done it, yet again.
