The variety is good, including domestic murders and suspicious deaths, at first thought to be suicide but later found to probably not be. The book is well written and and keeps you engaged with good build-up and post-crime information. The variety of crimes and settings also helps.
All these crimes took place long before DNA evidence and mass camera surveillance were things, so maybe that would have caught some of the murderers out otherwise. Truthfully though, if you have no link to the victim and no one actually witnessed you committing the crime then it is a lot easier to get away with murder than you might imagine. Or fear.
