Blood Link by Claire McNab

Is Carol playing into a killer's plan?

A series of random deaths suddenly fall into a pattern when reclusive, eccentric billionaire Thurmond Rule dies, leaving an immense estate, but no valid will. With no close relatives -- Rule's son and only heir vanished mysteriously years before -- the search begins to find more distant kin who may have a claim to the Rule billions. And there would be several more applicants vying for the money, except for the disturbing fact that many of them have recently died or been killed.

Detective Inspector Carol Ashton speculates that one of the remaining would-be heirs could be responsible for thinning the field so drastically, but is baffled that a killer would draw such obvious attention to themselves. As the authorities contemplate protecting anyone with a blood link to Thurmond Rule, Carol fears she may be unwittingly shielding a killer and playing into a deadly plan . . .

With another in the phenomenally successful Detective Carol Ashton Mystery series, Claire McNab again proves why she is the most popular writer of lesbian mysteries with this suspenseful story of cat and mouse.
