I haven’t read this historical mystery author (William Ryan), but the series looks interesting. And, per SYKM, three of the four books in the series have been finalists for various Dagger awards from the British Crime Writers Association – including the first one, The Holy Thief, which recently dropped to £0.99 at Kindle UK. Be careful, though, because The Holy Thief was on sale a while back, in a different edition, from Pan Books, and doesn’t show up as previously purchased on the web page for this newer e-edition. So check carefully before you buy!
