Mapped Out Murders - The Crime and Persecution Series, #1

Sarah Groben's an LAPD Homicide Detective and a Pastor's wife. But she's got six murders she hopes to solve by Sunday. A fledgling group of transplants from 10-40 window countries are being killed because of their Christianity. A Muslim charity interested in better relations with Americans seems to be connected by the death of a former financial manager. Family members of the victims might also end up in the crosshairs if Sarah is right about a "Persecutor for Hire." Sarah's partner is down with the flu and her husband Don seems like a tailor-made substitute with his knowledge of Middle eastern languages and cultures.
But the case keeps getting more complicated by the minute, and Sarah and Don might not be able to crack it before the killing starts again.
