The first two books in the John Decker series, and the John Decker prequel novella, Soul Catcher. 

In New York City, Homicide Detective John Decker arrives at a brutal crime scene. A man has been tortured and murdered in his own house, a sprawling mansion on the Upper East Side. But this is no ordinary home invasion. Nothing has been taken, and there appears to be no motive. Until beautiful Egyptologist Emma Wilson shows up with an enigmatic letter penned by the victim. 

The fossilized remains of a previously unclassified hominin species are discovered in the Altai Mountains, prompting teams of scientists from around the globe to converge upon this isolated region of Siberia in search of further evidence to corroborate the revolutionary theory that a third proto-human ancestor coexisted with Neanderthals and primitive Homo sapiens. What awaits them is anything but extinct.

On a desolate beach in far northern Scotland, the winter storms have been washing up all manner of things since time began. But buried in the centre of one smaller iceberg is a shard of ancient Viking pottery telling a partial tale of a hidden mysterious island beyond the ice and mist, that was home to a great treasure and even greater horrors. Thawing in the same block of ice was a rotting flap of skin that refused to be identified but had similar skin patterns to a creature not seen for 100 million years.
