Series numeration from GoodReads.com.

An obesity treatment has been discovered, but a dispute breaks out about who owns the discovery. David Marchmont, a patent lawyer, is asked to handle the case, but crucial evidence is missing - evidence that might have a bearing on a death of a student in a clinical trial two years before. David has his own challenges: his daughter Chloe has a rare and serious genetic condition. His wife Rachel becomes friendly with a young researcher, Kate Flanagan, who is seeking a cure for Chloe's disorder; Kate, in turn, becomes concerned that her lab colleagues may be cutting corners on the obesity drug. As evidence mounts - or disappears - Kate, Rachel and David find themselves caught up in acute ethical challenges and personal danger.
