Stalking Susan by Julie Kramer

Minneapolis TV reporter Riley Spartz is looking for the next big story when a source tells her about two women named Susan who were murdered a year apart over a decade ago. Their killers were never found and Riley's source, retiring homicide detective Nick Garnett, figures she might be able to succeed where the cops failed, especially since he feels the cases are connected. Riley soon finds other Susans who were possibly murdered, but has several suspects and not a lot of concrete evidence to narrow the list down. In her personal life, Riley is recovering from losing her husband so early in their marriage. Riley is trying to juggle grabbing great ratings for her stories while mending her broken heart. Stalking Susan is more of a mystery than a thriller and, while not quirky like Evanovich's Stephanie Plum series, it does have the same feeling--female amateur detective but not really cozy.
