The first sample is the one that starts with the music. Don't be shy - comment if you want -- I need to know for the second book 'Lead Weight.'
Sample #1 is on audiobooks and starts at the beginning of the story https://www.audiobooks.com/audiobook/chasing-mercury/306482
Sample # 2 is on audible/amazon and starts a few chapters in.
Which is most likely to make you want to read or hear there of the book -- starting randomly or starting at the beginning?
