Both authors portray their characters, particularly their protagonists, as the most complete, 3-dimensional individuals I’ve read. Connelly’s Harry Bosch novels, set in LA, and Sandford’s Lucas Davenport “Prey” series, set in Minneapolis-St. Paul, feature two wealthy police detectives. Davenport is tied to a witty and equally interesting surgeon girlfriend he marries later in the series named Weather Karkinnen while Bosch remains a bachelor.
Sandford created Davenport as a no-holds-barred investigator who has no qualms about skirting the law and department procedures to solve cases. Connelly made Bosch not as free-wheeling as Davenport but no stranger to bending a few rules. Both investigators face off against some tough antagonists and frequently find themselves on the short end. They have to use some creative detective work to pull their proverbial butts out of the fire.
Both these authors write in third person POV and publish novels you can’t put down. Read one from each and see if you agree.
