New York Times bestselling author Tess Gerritsen knows how to expertly dissect a brilliantly suspenseful story, all the while keeping fascinated readers riveted to her side. By turns darkly enthralling and relentlessly surprising, The Keepsake showcases an author at the peak of her storytelling powers.

For untold years, the perfectly preserved mummy had lain forgotten in the dusty basement of Boston’s Crispin Museum. Now its sudden rediscovery by museum staff is both a major coup and an attention-grabbing mystery. Dubbed “Madam X,” the mummy–to all appearances, an ancient Egyptian artifact–seems a ghoulish godsend for the financially struggling institution. But medical examiner Maura Isles soon discovers a macabre message hidden within the corpse–horrifying proof that this “centuries-old” relic is instead a modern-day murder victim.

To Maura and Boston homicide detective Jane Rizzoli, the forensic evidence is unmistakable, its implications terrifying. And when the grisly remains of yet another woman are found in the hidden recesses of the museum, it becomes chillingly clear that a maniac is at large–and is now taunting them.
Archaeologist Josephine Pulcillo’s blood runs cold when the killer’s cryptic missives are discovered, and her darkest dread becomes real when the carefully preserved corpse of yet a third victim is left in her car like a gruesome offering–or perhaps a ghastly promise of what’s to come.

The twisted killer’s familiarity with post-mortem rituals suggests to Maura and Jane that he may have scientific expertise in common with Josephine. Only Josephine knows that her stalker shares a knowledge even more personally terrifying: details of a dark secret she had thought forever buried.

Now Maura must summon her own dusty knowledge of ancient death traditions to unravel his twisted endgame. And when Josephine vanishes, Maura and Jane have precious little time to derail the Archaeology Killer before he adds another chilling piece to his monstrous collection.
