Throughout this new addition to my Spenser series, Parker keeps our favorite detectives emotions in check. The plot opens as Susan Silverman, longtime girlfriend of Spenser, asks him to investigate the alleged sexual harassment charges against her ex-husband, Brad Sterling. Quickly this case morphs into a multi-murder case, and Spenser finds it difficult to help Sterling while considering him as a suspect. This brings obvious internal struggle for him, as well as some hard pressing and action-packed scenes between him and shady characters involved in money making scemes. Dialogue is quick, with a bite, as can be depended upon in Spenser novels. A devoted reader of Parker's, I noticed most of the story based on the relationship between Susan and Spenser, with that perhaps overcoming the actual mystery. However, Parker writes with enough sass that every new insight into their relationship was devoured. Light on action, but definitely a quick read, a solid Spenser read. A must read for Spenser fans, and anyone else outside the club will instantly fall in love after reading Sudden Mischief.
