Maitland 1913. Miss Elizabeth Quinn is something of an institution in Maitland Town. For longer than anyone can remember she and her brother, businessman Michael, have lived in the impressive two-storey stone house next to the church. When she is discovered cowering in the corner of the exhibition gallery at the Technical College the entire town knows something strange has come to pass.

Was it the prehistoric remains or perhaps the taxidermy exhibition that had reduced the whalebone-encased pillar of society to a quivering mess? Or is there something odd about a striking painting on loan from the National Gallery?

Mathematical savant Jane Piper is determined to find out. Deposited on the doorstep of the local orphanage as a baby, she owes her life and education to the Quinns’s philanthropic ventures and Elizabeth has no one else to turn to.

As the past and the present converge, Elizabeth’s grip on reality loosens. Can Jane, with her logical brain and penchant for puzzles, unravel Elizabeth’s story before it is too late?
