Carpenter and Quincannon, Professional Detective Services is a fixture in San Francisco at the dawn of a new century. While the future is unclear, Sabina and John know one thing for certain; they will protect their clients from flimflammers, thieves, and murderers, and do whatever it takes to run these dregs of society into the arms of the law. Sometimes, that requires a subtle touch. Professor A. Vargas, self-styled medium extraordinaire, and his partner Annabelle, use guile and trickery to swindle bereaved men and women eager to contact the spirits of deceased loved ones. John and Sabina must not only unmask these charlatans, but also solve the riddle of an impossible murder in the midst of a séance. Other cases involve brute force and personal danger. Such as the theft of a burglarproof safe mysteriously emptied of gold bullion.
