I wasn’t sure about the narrator’s voice, at first, but I think he did a great job of portraying Ben’s alternate time-line son. Exactly what caused the paradox, we’re not told, but it’s alluded to often, with the emphasis on this Grayson trying to avoid a paradox at almost any cost!
I loved this smart-talking quick-witted PI, who has definitely got a unique way to solve mysteries, although, even without his chronometer, he’s pretty good at working out who dunnit in linear time.
As a big fan of this time travelling family, I can’t wait for more Grayson Travers stories!
