Definitely not my cup of tea! This was about murder but it bore me to death with all the details about fluorescent printing and DNA tracing. 
 I realize I only enjoy crime novels where the reader got to know all the suspects and develop a personal connection with all of them, e.x Agatha Christie. This makes the novel more interesting as the reader got to use his knowledge to guess who is the killer, constantly piercing the clues together to arrive at the truth. Plus, these novels reveal the depth of human nature and the philosophy behind their killing, making the reader understood their motives and comprehend their nature. 
 Postmortem, on the other hand, is dull. The killer is not someone we know, a guy outside the scene, so there was no desire or suspense in wanting to discover him. The clues given us to us are indecipherable, because it is too technical and the reader has no choice but to nod along as the detective explain what happens. This put the reader in a passive role, like Watson in Sherlock Holmes, but Holmes was slightly more entertaining and his explanation is understandable. Similarly, my other favorite crime novels like Christie and Tana French or Gilliam Flynn, makes me stay up all night because I got to exercise my psychological profiling skill to suspect left and right: is it the psychotic mother, or the seemingly benign boyfriend? The guess game is fun! 
 Postmortem, on the other hand, is just your average serial killer going around killing people, like reading a newspaper report. 
 Also a few inconsistencies I like to point out: 
 1. Why Dr. Kay did not report to the police immediately when she heard a strange call in the night immediately after the death of the fourth victim? If I was her, I would know immediately that the killer has targeted me, and I would proceed to inform the police immediately, yet Dr. Kay just go to bed and sleep like nothing unusual happen. 
 2. When she was in the morgue, someone said the body of a victim (hit by a train, I think) went missing. Dr. Kay did not seem to react, but the paragraph skip immediately to something else entirely different, which again, make it seem like Dr. Kay does not really care about the incident. 
 3. When Dr. Kay's computer was known to be accessed by someone unknown, her immediate concern was about her career, and the paragraph went on and on about a meeting she has with the boss and how she felt humiliated about the affair and wanted to hide it from him. Yo, the killer is stalking you! He called your house, he had accessed to the morgue, and now your computer. Three red flags! I would immediately install the latest security system and surveillance camera on my door immediately. Dr. Kay, on the other hand, just chill. And guess what happen in the end? 
 SPOILER alert. 
 she was nearly killed by the serial killer! well, since she had no common sense that's why! He had stalked her from Day 1 and yet she ignore all the red flags! 
 At any rate, this novel isn't that bad. It was just boring to me. but if you enjoy standard crime novel about blood and women being rape/murdered then this is for you. I prefer my novel's killer to have more of a personal touch.
