The Inspector Bonaparte (Bony) series by Arthur W. Upfield was one of the earliest mystery series that I read, after discovering mysteries via, of course, Agatha Christie
. I still have an almost complete set of DTB, and was eagerly waiting for this series to become available in ebook in the US. Since the series came out in the US though, sadly I've been waiting for either:
(1) titles to go on sale, since they are mostly priced at $6.99 ($5.66 at Kobo with VIP), and that is way too expensive to replace DTB, no matter how much I want to recover shelf space
, or
(2) me to travel to Canada or another country where they are PD, and then download those that are available from Faded Page and other PD websites, although not many are available.
In the meantime, though, one random title in this series has dropped to $4.49 at Kindle US...still not cheap enough for me to replace a DTB, but someone else may be interested in it...that's about 35% off, which is something. It's still showing at normal price at Kobo US, at least as of now.

As with many series from this time frame, the protagonist takes time from traditional mystery-solving to serve with his/her country's military. These are usually not my favorite titles in a series, but YMMV...
