MAJOR SPOILER ahead. If you have not read the eBook or listened to the audio book go no further if you want to figure it out on your own.
Still with me then? I knew from the first chapter that Mary Russell survived the encounter with Samuel Hudson It was all wriiten in first person narrative.
I did not have all the answers though I knew most of the blood on the floor was Samuel's. First person narrative cannot be written by a ghost in a Sherlock Holmes/Mary Russell Mystery. What I want to know is when it was obvious to other readers or listeners.
