Hidden in Plain Sight, RMT644A

Most of us keep something hidden. The protagonists here have taken that approach a little too far. A police scientist hides his true vocation behind a new fiancée. A woman serves years for a killing she swears she didn't commit, while a former assassin buries his past in a Mexican kitchen. And a young widow wonders whether the sea really took her husband. The truth is buried, and someone will kill to keep it there. Trust nobody, and read with the lights on!
