This is the first book in the series. I have listened to the books out of order and each one stands alone. Finally, I get to see how it all started! John Pickett, a Bow Street Runner (Early British policeman) is called out to investigate the murder of Lord Fieldhurst. The prime suspect in the case is his wife and Pickett somehow believes her innocence even though the cards are stacked against her. This is a great mystery series, and you will want to read all the books! The narration in each book is absolutely fabulous and sounds like a full cast production. I was gifted a copy of this audiobook at my request in exchange for an honest review.
