Scent of Danger — Tim Arnold

Nick Phillips, cardiologist, loses his wife and unborn child in a tragic car accident. All his years of training are of no use as they die before his eyes in the emergency room. In grief he steps away from medicine, hiding from himself and the world, and searching for direction in his life.
Marcie Corrandini, the beautiful daughter of Europe's reigning Mafia Don, must find a heart surgeon for her ailing father, someone who doesn't realize who he is, will travel and do whatever is necessary to keep him alive.

She is being followed by Interpol, and they want to know what she is up to as she travels to Paris to do business for her father's legitimate enterprises and to research cardiologists.

When she contacts Nick's best friend, Jim Franks, still employed by the CIA, can't resist an opportunity to gain intimate knowledge of the Corrandini family. Interpol's agent, Hans Mueller, has been watching the Corrandini Family for years and will do anything to get this doctor placed on the Corrandini yacht in Monaco.

Events unfold forcing Marcie to run for her life alone. Once again Nick is left searching.
