**New, has faint age discoloration on inside page (see picture) On any given day in London, all Charles Lenox, Victorian gentleman and armchair explorer, wants to do is relax in his private study with a cup of tea, a roaring fire and a good book. It's a nice life. But when his lifelong friend Lady Jane asks for his help, Lenox cannot resist another chance to unravel a mystery, even if it means trudging through the snow to her townhouse next door. One of Jane's former servants, Prudence Smith, is dead -- an apparent suicide. But Lenox suspects something far more sinister: murder by a rare and deadly poison. The house where the girl worked is full of suspects and, though Prudence dabbled with the hearts of more than a few men, Lenox is baffled by an elusive lack of motive in the girl's death. When another body turns up during the London season's most fashionable ball, Lenox must untangle a web of loyalties and animosities. Was it jealousy that killed Prudence? Or was it something else entirely different, something that Lenox alone can uncover before the killer strikes again?
