Connelly excels at creating intriguing plot lines that he fleshes out with realistic details, resulting in storylines that ring very true, which is essential for my enjoyment of any mystery novel. I guess Connelly's years as a crime reporter for the LA Times pays dividends in his ability to accurately portray crimes and the criminal mind.
His most popular series features detective Harry Bosch. Hieronymous (Harry) Bosch is a detective in the classic style, one who will stop at nothing to protect the vunerable. Someone who may break a few rules when necessary to impart his sense of justice and is a loner who has his own demons that torment him. The settings of Hollywood and Los Angeles are also key ingredients in this series, providing a backdrop full of greed, sleaze and shattered dreams.
If you like Detective Harry Bosch, you might also enjoy:

Strong characters and complex storylines define this series.
