In between New York and New England we spent a couple of nights in Boston. One of my favourite authors is Tess Gerritsen, who sets her Rizzoli and Isles novels in the city. As a fan of the TV show as well I was quite excited about the prospect of finding the police department where it is filmed. Until Mr F did a quick internet search and found the show is actually filmed on set miles away from Boston. We had to content ourselves with following the freedom trail instead, which came with a handy painted line on the road to follow so no map reading necessary.
