The Forty-Eight-Hour Gap: A Pelican Point Senior Sleuth Mystery (Book 3). Pelican Senior Sleuth Mystery Series, #3

Retired Treasury investigator Margot Sterling came back to Pelican Point expecting quiet. No active case. No yellow pad filling with notes. No reason to worry her daughter by admitting that retirement has never quite cured her of noticing what other people miss. Then Celeste Moreau arrives. Elegant, private, and precise, the new resident of Egret Tower claims to be a retired museum administrator from Montreal.
But Margot sees what others do not: the way Celeste studies every exit, the way she opens locks without looking, the way her entire life seems carefully built around not being found. When Celeste is discovered dead only days after moving in, the community is ready to call it a tragedy. Margot is not. Because Celeste Moreau may not have been Celeste Moreau at all. The trail leads back nearly forty years to Newport, Rhode Island, to a powerful family, a suspicious estate fire, a woman declared dead without proper identification, and a record that was quietly altered before anyone knew to question it.
As Margot follows the paper trail from Pelican Point to old archives, private journals, forgotten photographs, and a name someone has spent decades protecting, she realizes Celeste was not running from the past. She was bringing it with her. And someone at Pelican Point may have killed to keep that past buried. Smart, atmospheric, and quietly gripping, this Pelican Point mystery is perfect for readers who enjoy senior sleuths, coastal settings, cold cases, hidden identities, and mysteries where the smallest inconsistency can expose the deepest lie.
