This week, I’m giving away two mysteries whose authors’ names begin with R.

Although Marcie R Rendon is known for her Cash Blackbear series, Where They Last Saw Her is a standalone. It’s a thought-provoking book. Quill has lived on the Red Pine reservation in Minnesota her whole life. She knows what happens to women who look like her. Just a girl when Jimmy Sky jumped off the railway bridge and she ran for help, Quill realizes now that she’s never stopped running. As she trains for the Boston Marathon early one morning in the woods, she hears a scream. When she returns to search the area, all she finds are tire tracks and a single beaded earring. Things are different now for Quill than when she was a lonely girl. Her friends Punk and Gaylyn are two women who don’t know what it means to quit; her loving husband, Crow, and their two beautiful children challenge her to be better every day. So when she hears a second woman has been stolen, she is determined to do something about it—starting with investigating the group of men working the pipeline construction just north of their homes. As Quill closes in on the truth about the missing women, someone else disappears. In her quest to find justice for all of the women of the reservation, she is confronted with the hard truths of their home and the people who purport to serve them. When will she stop losing neighbors, friends, family? As Quill puts everything on the line to make a difference, the novel asks searing questions about bystander culture, the reverberations of even one act of crime, and the long-lasting trauma of being considered invisible.

Who can resist that face on David Rosenfelt’s thirtieth Andy Carpenter mystery, The More the Terrier? Reluctant lawyer Andy Carpenter is relieved to be headed back to Paterson, New Jersey, after a week-long family vacation in the Adirondacks. He’s ready to put the holly jolly season way behind him and settle in at home with his three dogs. But when they finally arrive, there is an extra dog eagerly awaiting them, as well as one anxious dog sitter. When the dog showed up on the doorstep a few days ago, the sitter knew Andy would know what to do. Indeed, Andy recognizes Murphy, who the Carpenters fostered before the dog went home with BJ Bremer and his mother. BJ wanted to learn all he could about caring for Murphy, which made Andy like him immediately. When Andy goes to take Murphy back to the Bremers, though, instead of the happy reunion he expects, he finds BJ’s mother in tears. It turns out Murphy ran off…after BJ was arrested for murder. Andy had hoped for a quiet Christmas vacation, but he likes Murphy’s family and his golden retriever, Tara, likes Murphy, so he can’t resist getting involved. The case isn’t as simple as Andy thought it would be, though, with BJ suspected of murdering one of his professors. With nothing to go on but Andy’s own conviction in BJ’s dog-loving character, proving his innocence would be a Christmas miracle.
