Cataloguing the Bones

It's a whale bone, said the donor. The accession number says 1893. The cut marks say three months ago. Curator Lena Marsh has spent her career authenticating objects; now she has to authenticate a murder that somebody hid inside a museum donation. Three estates, two missing people, and a family whose accidents keep adding up. When the evidence is complete, she presents it at the donors' dinner, in front of the family that funded the wing. A we-solve-murders mystery for readers who like their clues catalogued, their suspects wealthy, and their amateur sleuth the only person in the room who reads the small print.
