It looks as if someone (the author? someone else?) has gotten the rights back to at least the first few books in the Lord Edward Corinth & Verity Browne series by David Roberts, which were previously published by Carroll & Graf. And right now the first three titles, issued by a new publisher, have dropped to $0.99/£0.99 each at Kindle US/UK. The fourth is $2.99/£2.99, which is still not bad, and the fifth is on pre-sale at $0.99/£0.99.

Also note that there used to be an omnibus of the the first four titles in this series that would go on sale from time to time, so check carefully before you buy. And of course, if you already have the individual titles from the previous publisher, they won’t show up as purchased on the new individual webpages either – just in your library…
I read and enjoyed several of the early titles in this series (including these five) as paper books, picked up on business trips to the UK. But the later titles were mostly a little too expensive in e-book for me. Fingers crossed that they’ll come out at more reasonable prices now…
