Death of a Poison Pen
M. C. Beaton
This is the 20th book in Ms. Beaton's Hamish McBeth series. Hamish is the constable in a small Scottish Highland town and likes it. He resists promotion and solves murders. The BBC has adapted a number of these stories to a series which has increased the worldwide popularity.
These books are a bit more than cosy's, but they are usually straight forward and uncomplicated. Just the thing to read while recovering from surgery. The length of the books has increased since the series became available, but they are still not too long and quick reads. I recommend the series.
