Whispers Under Ground Google Map by Ben Aaronovitch

So just like he has done so with the previous two books, Aaronovitch has created a Google Map marking different locations from the third Peter Grant book, Whispers Under Ground. You can check it out here. He has also said on his blog that he will be creating a Google Map for Broken Homes locations when the book is finally released in the US.

Broken Homes is out now here in the UK and due out in the US in February 2014.
