Though by no means professional detectives, my new favorite sleuths, Veronica Speedwell, and her partner in crime, Stoker (that's Lord Revelstoke Templeton-Vane), are back in another mystery. An unexpectedly royal familial source asks Veronica to look into the case of a high-society gent who is about to hang for the murder of his mistress. Lots of behind-the-scenes machinations, both helpful and threatening, provide direction and impediments as the lepidopterist and taxidermist use their powers of observation, their fighting skills, and their insatiable curiosity to prove whether this man should swing from the gallows or be rescued from the hangman's noose.
