Don Neven, a retired software engineer and immigration rights activist, is found bludgeoned to death at the Sunrise Acres golf club. Shortly before his death, Don entrusted his friend Irwin Robeson with a thumb drive containing crucial software code Don had created for a solar startup company Don was mentoring. Could there be a link between the code and Don’s death? Or is it more likely that Don’s activism, which has evoked hate mail and threats, has led to his violent demise? Don’s estranged brother Buddy Neven, the likely beneficiary of Don’s estate, has reason to wish Don dead. Molly had befriended Buddy and is convinced of his innocence, but Mike isn’t so sure.  How will the police team, headed by Detective Jose Villegas, sift through the complex motives to find the killer? And how will Molly and Mike get involved in the case, as they have in their two previous murder investigations?
