From the author of the acclaimed Li Du novels comes Elsa Hart's new atmospheric mystery series.

London, 1703. In a time when the old approaches to science coexist with the new, one elite community attempts to understand the world by collecting its wonders. Sir Barnaby Mayne, the most formidable of these collectors, has devoted his life to filling his cabinets. While the curious-minded vie for invitations to study the rare stones, bones, books, and artifacts he has amassed, some visitors come with a darker purpose.

For Cecily Kay, it is a passion for plants that brings her to the Mayne house. The only puzzle she expects to encounter is how to locate the specimens she needs within Sir Barnaby's crowded cabinets. But when her host is stabbed to death, Cecily finds the confession of the supposed killer unconvincing. She pays attention to details--years of practice have taught her that the smallest particulars can distinguish a harmless herb from a deadly one--and in the case of Sir Barnaby's murder, there are too many inconsistencies for her to ignore.

To discover the truth, Cecily must enter the world of the collectors, a realm where intellect is distorted by obsession and greed. As her pursuit of answers brings her closer to a killer, she risks being given a final resting place amid the bones that wait, silent and still, in the cabinets of Barnaby Mayne.
