Brian and Roni are looking for another case to crack when Roni finds an age-progressed picture of a boy who looks alarmingly like Brian on a missing children website. Brian is sure it is only a coincidence—after all, he’s lived happily with his adoptive parents for as long as he can remember. But then again, his parents have never really told him about his adoption . . . Could there be more to his family history than he knows? As Roni and Brian piece together the clues, other people emerge from the shadows of the past and suddenly Brian isn’t just a detective on the case—he’s the key to a mystery that everyone is after. Can he and Roni uncover the truth before it’s too late? Featuring the strong plotting and offbeat humor that won the Bloodwater Mysteries a prestigious Edgar nomination, Doppelganger is full of twists and turns that will keep readers guessing until the very end.
