Stolen in Death (In Death, 62) by J. D. Robb

A violent death and a vault of stolen treasures has Eve Dallas struggling to solve crimes old and new in the next thriller in the #1 New York Times-bestselling series.

A blow to the head with a block of amethyst has left multibillionaire Nathan Barrister dead―while nearby, a vault, its door ajar, sits filled with priceless paintings, jewelry, and other treasures. Lieutenant Eve Dallas’s husband, Roarke―who misspent his youth in Ireland as a scrappy thief―recognizes at least two stolen pieces among the hoard. The crime scene suggests a burglar caught in the act. But only one item seems to be missing.

Then it’s revealed that the vault had actually belonged to the victim’s late father―and no one in the household knew it was there until a recent remodeling project exposed it. To protect the family name and business, they explain to Eve, they’d been looking for a way to return the ill-gotten gains anonymously and avoid the police. But now the police are all over their elegant house, and have a bigger, bloodier mystery to solve.

By all accounts, Nathan Barrister was a good man, a generous employer, a devoted husband and father. As for his father―he clearly had secrets. Now it’s up to Eve and her team to find out if those secrets got Nathan killed―and if it was a crime of passion or revenge.
