A Hovering of Vultures — Robert Barnard

Reclusive brother and sister authors Joshua and Susannah Sneddon seemed happy enough to grind out their dreary literary tomes in their cozy Yorkshire cottage -- until Joshua took a fatal ax to his unfortunate sibling before putting a bullet into his own skull.

A half-century has passed since the dramatic murder/suicide -- and a smarmy entrepreneur intends to open a Sneddon museum on the double death site. The impending event is attracting eager "Sneddonites" from around the world -- but Detective Constable Charlie Peace smells a rat. For there are sinister, long-buried secrets that must be disinterred before the groundbreaking...and more blood is most assuredly going to be spilled.
