This is the 10th book in the series. I have listened to the books out of order and each one stands alone. In this story, John Pickett, a Bow Street Runner (Early British policeman) discovers he has a previously unknown family member and returns to the place where he grew up.
One of the runners is present at a robbery turned murder where a young child is part of the gang. Under English law, this child will be executed, even if he did not commit the murder, John Pickett is called in to help the child even if it undermines the Bow Street investigation. A very riveting story!
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.
