Books like The Bone Yard by F. Paul Wilson

When a coastal dog retrieves a bone that turns out to be human, Isa Wilde’s idyllic village of Salten is thrust into terror as her childhood friends uncover a dark secret, unraveling their shared past.

Husband-and-wife team Sam and Remi Fargo are intrigued when an archaeologist friend requests their help excavating a top secret historical site. What they find will set them on a hunt for a prize greater than they could ever imagine. The clues point to the hidden tomb of Attila the Hun, the High King who was reportedly buried with a vast fortune of gold and jewels and plunder . . . a bounty that has never been found. As they follow the trail through Hungary, Italy, France, Russia, and Kazakhstan--a trail that they discover leads them not to one tomb, but five--the Fargos will find themselves pitted against a thieving group of amateur treasure hunters, a cunning Russian businessman, and a ruthless Hungarian who claims direct descent from Attila himself . . . and will stop at nothing to claim the tombs' riches as his own.

"I very much need to be dead." These are the chilling last words left by a man who had everything to live for but took his own life. In the void that remains stands his widow, FBI agent Jane Hawk, surrounded by questions destined to go unanswered unless she does what all the grief and fury inside her demand: Find the truth, no matter what. People of talent and accomplishment, people seemingly happy and sound of mind, have recently been committing suicide in surprising numbers. A disturbing pattern is beginning to emerge. Jane is determined to give up everything to find out why. And if that means going rogue and becoming America's Most Wanted, then so be it. Those arrayed against her are legion, and devoted to protecting something profoundly important-or terrifying-enough to exterminate any and all in their way. But Jane is as clever as these enemies are cold-blooded, as relentless as they are ruthless. And she is driven by a righteous rage they can never comprehend. Because it is born of love.
