Obstetrician Hannah Kline and her brand new fiance, LAPD Detective Daniel Ross, are about to begin house hunting when Daniel is put in charge of a high profile murder investigation.

Dr. Edwin Larramore was at the top of his game. A full professor of Astronomy at the prestigious Technological Institute, and a leader in the search for extrasolar planets, he has just been awarded the Nobel Prize for an extraordinary discovery. Who would want to kill him?

There turns out to be no shortage of suspects. The victim had an unhappy pregnant wife, an angry ex-wife (who is also his chief academic competitor), a jealous department chairman, and several under-appreciated and disgruntled graduate students. Daniel has his work cut out for him.

Hannah has been very helpful in several of Daniel's previous cases, but this time her hands are tied. Larramore's pregnant wife is her patient and medical ethics prevent her from telling all she knows. But when Hannah discovers a crucial clue, and her patient's pregnancy becomes high risk, she has to resolve her conflicting loyalties.
