With a spreading typhoid epidemic in New York City, Daniel arranges for Molly to leave the city for an investigation in the country. The Flynn’s son was kidnapped, and his mother hopes to make contact with him through spiritualists. She arrives at Senator Flynn’s house to prove that they are fakes, and becomes involved in solving the kidnapping. This was not as good as the rest of the series has been, with some plot twists stretching a bit to make the connections. But worth reading if you liked the previous stories. And the ending sets up an important plot-line for the next book.
