Abstract:
When Jonathan Calvert acquires the gorgeous Castrovillari emerald necklace, he has it displayed at the Opera, that night, by young Nancy Courtenay. A few hours later, Calvert is found dead in a taxi. The autopsy shows that it is murder by poison.
Peter Lynnfield and Inspector Dorrington strive mightily to untangle a web of Italian treachery and murder. Can they succeed? There are so many suspects, and despite their efforts, the murderer, again and again, skillfully manages to slip away, until his reckless daring brings about his demise.
