Books like The Deadly Hours by Susanna Kearsley

Archaeologist Verity Grey ventures to Scotland’s Southern Borderlands in search of the vanished Ninth Roman Legion, only to confront haunting legends and buried secrets that challenge both history and her own convictions.

"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.

A contemporary Scottish writer uncovers a secret from 1708 involving a Jacobite invasion and a long‑lost tragedy, as a haunting ancestral memory threatens to unleash the buried truth for all to see.

When reclusive novelist Vida Winter’s health wanes, she tasks biographer Margaret Lea with revealing the truth of her life, though Margaret must sift through Winter’s penchant for exaggeration to arrive at facts.
