Vital Signs (novel)

Vital Signs is a novel by Robin Cook. Like most of Cook's other work, it is a medical thriller. It's about a successful epidemiologist and married woman Marissa Blumenthal. When she discovers that she cannot conceive, her obsession with getting pregnant leads her to investigate the baby-making business.

Dr. Blumenthal finds out that she cannot conceive as her fallopian tubes are blocked due to a case of TB, which she feels is extremely rare in current times. She tries to conceive through a modern technique called in vitro fertilization from a very well known fertility clinic, but after four unsuccessful cycles she and her husband start to have differing opinions about continuing their quest for child. This starts to take a toll on their relationship, as Marissa is adamant to go on for the next cycle and her husband thinks that it would be another $10,000 down the drain. Marissa joins a counseling group for such in vitro couples, and meets up with her medical school friend Wendy, who also shares that same medical condition as her. Soon the two women discover that the specific condition is found in numerous women being treated in the clinic where they are getting treated. A suicide (suggested to be a murder) of fellow woman patient in the clinic also add to their curiosity. They break into the clinic and try to read their medical records, which are kept in a highly confidential status in the clinic.

They find out that a pathologist, Dr. Tristan Williams, from a clinic with similar name in Australia, has written a paper about a condition similar to theirs. On the spur of moment, they decide to go to Australia to visit the author. When they inquire about him at the facility, they get negative responses and are made to believe that they have made a wasted trip. When Wendy is killed in an unexpected accident involving shark, Marissa feel that her death is more than an unfortunate accident. After few fruitless efforts to find Dr. Williams, Marissa meets him in his current assignment. From him she learns about a practice where pairs of Chinese citizens who were smuggled into Australia work in the clinic regularly. Tristan tells Marissa that due to the paper he wrote, the FCA has taken retaliatory steps against him, like branding him with drugs and killing his wife two years ago. He has had to be constantly on the run, which made him send his only son to live with his in-laws to keep him safe. Marissa and Tristan team up together to get to the bottom of the mystery.
