My enthusiasm for Paul Doherty's series, "the Sorrowful Mysteries of Brother Athelstan," has been documented on this blog before. I reviewed the first of these books, The Nightingale Gallery, a couple of years back and returned to Doherty to review one of the more recent ones, Candle-Flame. Regular visitors will know that I really enjoy good "impossible crime" mysteries, and all the ones that I have read so far in the Brother Athelstan series have fit into that category. I know some readers prefer to read them in order, but I didn't find it essential to my enjoyment of the ones I've read.
Paul Doherty has written more than 80 books so far, in several series set in a variety of different locales and time periods and with a lot of different sleuths. If you'd like to learn more about him, the Wikipedia article has additional details and bibliographies. I'd also recommend very highly that you read some of the relevant posts made by two other mystery bloggers - in fact, they are the ones who first called my attention to Paul Doherty, and I'm indebted to them both. The blogger who calls himself The Puzzle Doctor blogs at In Search of the Classic Mystery Novel, where he frequently writes about Doherty's books. Over at the Beneath the Stains of Time blog, you'll find the blogger who uses the names TomCat and Last Century Detective is another Doherty reader. I commend them to you highly.
