I would say that this had a simple plot line to follow but was looking for that. I wouldn't say that these are in-depth and complex characters to follow but understandably consistent with the various personality types attempting to solve this mystery. A glimpse into the dark side of NYC at this period of time. A steady build up to catching the killer and witnessing the origins of what was to become forensic police work and profiling as we know it now. An easy ride along with the various characters and their hidden pasts and how they link to the potentially worst sides of human nature. A murder mystery to definitely absorb yourself into.
