I have recently been watching a programme called Grantchester on ITV and I must say it is great.
A Reverend who makes a new friend in a police inspector; together they set aside their differences to solve recent murders. The programme is set within the 1950's and is a breath of fresh air...I have recently purchased the book and I can't wait to start it soon!
I recommend viewing this television programme.

Please note: I live in the UK, I am unsure whether it is available for other countries.
