Argylle

Sorry to say, this wasn't the greatest read. Audiobook narration (from the OG Lyra Belaqua funnily enough) was flat and uninspired, I don't think the content of the book helped either.

As to the mystery author, I think it's an American (based on the old “in London it rains all the time” cliche) male (based on IIRC the banter between the male characters)... Be interested to see what it turns out to be. Not a professional author IMHO. Turns out the film isn't all that anyway, shame as Vaughan has put out some entertaining stuff in the past.
