I really struggled with this book. I think Walker is still finding his style - and Bruno Prince of Detectives is by no means flawless - but golly this was dull.
I think the problem was Walker trying to interweave three lots of stories - including that of some early man troglodytes - in with a WWII and modern story. For me, it just didn't work. I couldn't sustain any interest in the troglodytes.
It may be me - I am glad others enjoyed it - but this one wasn't much fun.
I'm looking forward to the next Bruno, though.
(In case you've got a strange curiosity like mine, the tags Amazon suggested included "boring, highly recommended, crime, couscous, ex pat".)
