Gina Mazzio, RN, and fiancé Harry Lucke are on the brink of getting married when a childhood friend relocates from the Bronx to San Francisco. Within days, Gina’s nurse friend is relating difficult-to-believe horror stories about her new employer, a cardiologist whom she suspects is involved in illicit and deadly medical practices. Gina soon discovers the stories are true—the doctor is not only acting in an unethical manner, he may also be complicit in two or three hideous murders. That knowledge quickly makes her the new target of the doctor ... and a vicious hit man, who is determined to hunt her down and kill her.
