Set in Africa, this is a series that I've been very remiss in keeping up to date with.
From the Blurb:
Safari guide and private investigator Hudson Brand hunts people, not animals. He's on the trail of Linley Brown who's been named as the beneficiary of a life insurance policy.
Linley's friend, Kate, supposedly died in a fiery car accident in Zimbabwe, but Kate's sister wants to believe it is an elaborate fraud.
