In his first case, The Bone Field, Przewalski chases a missing paleontologist across 80 million years of intrigue and death, from a Wyoming bone field of petrified skeletons to the bone rooms of the museum.


In his second case, Death Spoke, the murder of an expert on prehistoric cave art immerses Przewalski in a famous painted cavern in France, a World War II atrocity, an archaeological fraud, and a diabolical act of revenge. Przewalski excavates the deadly archaeological layers of the case finding lives torn by deceit, vendetta and redemption.


In the third book of the series, The Camel Driver, a world famous museum diorama, Arab Courier Attacked by Lions, is vandalized––the glass smashed, the belly of the taxidermied camel slit open, a bundle removed. Is the Berber’s skull, skeleton & skin mounted under his clothing?  Harry uncovers the macabre history of the camel driver: a lurid sexual trial in South Africa, a secret journal in the Paris Museum, and an archaeological bombshell worth killing for.
