What to expect

Homicide detective partners Barbara Lassiter and Susan Martinez return in this third edition of the Lassiter/Martinez Case Files series.

Called in to investigate a mysterious death in a retirement center, Lassiter and Martinez find themselves entangled in a case that might very well involve multiple murders committed by a psychopathic killer. The deeper they get into their investigation, the more complex and dangerous the case becomes, threatening the lives of the detectives and their loved ones. Political and bureaucratic machinations within the detectives’ department and the involvement of organized crime only make their jobs more difficult.

Multiple award-winner and Amazon #1 bestselling author Joseph Badal offers up another suspenseful tale, with twists and turns that will put and keep the listener on a roller coaster ride of drama, action, and emotion from beginning to end.

Douglas Preston, #1 New York Times bestselling author

“Another outstanding entry in a terrific series. Detectives Susan Martinez and Barbara Lassiter are smart, tough, and compassionate protagonists worth rooting for. They are compelling police professionals, not super-human crime fighters. Joseph Badal’s plotting is deft, his pacing is perfect, and his writing crisp. Highly recommended.”

Natural Causes introduces one of the nastiest villains you’ll love to hate, one who offers a dangerous challenge to our two heroines…Compared to her, Mexican cartels are a bunch of bungling amateurs.”
