I read a lot of crime fiction, and over the last few years, I've been working my way around, visiting cities where the books are set.

Naturally, Oxford (Inspector Morse) is a city I'm very familiar with, but I've also notched up Edinburgh (Rebus) in February 2017, and tomorrow I'm off for a weekend in Brighton (Roy Grace).

That just leaves Aberdeen (Logan MacRae), Los Angeles (Harry Bosch, Numb3rs), and New York (Castle, Law And Order) to go!

OK, so I drifted from books into TV at the end there, but it's a hobby.
