I have listened to the books in this series out of order and each one stands alone. John Pickett, a Bow Street Runner (Early British policeman) and is going through a bad time and wishes he was never born. He hits his head, blacks out and suddenly finds that no one knows who he is anymore. This is a great mystery series, and this book has a different twist than the others. This story also answers some questions about John Picket’s past. 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.
