A young employee of the Olde World Gallery is suspected of stealing jewellery and even those that know her well suspect the worst. The list of crimes of which she is the alleged perpetrator then grows to include arson, and even murder. John Mannering (aka 'The Baron') comes to her aid and believes she is obviously being framed, but the evidence grows and there doesn't appear to be any other rational explanation. Moreover, as Mannering draws closer to the truth, those others who are suspected start to die, and the intrigue deepens.
