There are many reasons why a book might be unavailable.
Sometimes a book goes temporarily out of print - and sometimes no audio version has ever been recorded. Audible wants to give you the most complete selection we can and we'll keep adding series and filling in gaps as quickly as possible.
Excellent Appleby, excellently read. I don't really feel the need to review it, but I do feel the need for Audible to get the title right.
Genre-Bending Oddball Adventure
One of my favorite Innes books. Listened to it several times and I'm sure I will again. Great narrator.
One of my personal treasures. The art gallery, the anarchistic artist, above all Appleby's junk shop duel -- priceless wit with a reasonable plot.
Yes, due to the fine performance of the narrator, who has a seemingly infinitely flexible voice and brought every eccentric character vividly to life.
